Framework Types:

The model exhibits three dominant narrative frameworks:

● Authority Framework: Centered on clinical credibility and professional endorsements, primarily applied to descriptions of Oral-B and Philips Sonicare.

● Technology Framework: Focused on functional specifications, smart connectivity, and innovative imagery, mainly used in descriptions of emerging brands such as Oclean and Laifen.

● Lifestyle Framework: Centered on design aesthetics, personal identity expression, and daily rituals, primarily applied to descriptions of brands such as SURI and Foreo.

👉 The narrative structure is semi-stable: core tags (such as "dentist-recommended") remain highly stable, while specific narrative language fluctuates with evolving brand communications.

Regional Influence:

The model explicitly states in Q7 that significant differences exist in regional narratives. In North American and European markets, clinical credibility and dentist recommendation narratives carry greater weight; in the Chinese market, smart technology and cost-effectiveness narratives dominate; in Japanese and Korean markets, design refinement and hygiene perception narratives are more prominent; in Southeast Asian markets, accessibility and replacement cost narratives are more significant.

IP Influence:

The data collection node for this audit is a Japanese static residential IP. The model output shows relative attention to design refinement and compact products, but no direct causal relationship between the IP and output content can be proven. This phenomenon may reflect the model’s partial adaptation to the Japanese market context or may stem from differences in training data distribution.

Perspective Bias:

The model overall presents a narrative perspective benchmarked against Western mainstream markets. Chinese brands are systematically described as “challengers” or “emerging brands” rather than as global reference points alongside Oral-B and Philips Sonicare. This tendency is evident in Q1, Q2, and Q3.

Hierarchy:

Philips Sonicare and Oral-B were placed by the model in the first tier or highest perception tier across all eight Q&A sets, with extremely high consistency across questions.

Brand Identity:

Oral-B’s “Dentist Recommended” identity label, Philips Sonicare’s “Sonic Technology Leader” identity label, and Waterpik’s “Water Flosser Specialist Authority” identity label exhibit a high degree of stability in the model’s outputs.

Technology Anchor Points:

Sonic vibration and oscillating-rotating vibration, as the two dominant cognitive frameworks for brushing technologies, consistently appear from Q1 to Q7, forming a stable anchor for the model’s technical narrative of this category.

Ecosystem Perception:

The brush head replacement ecosystem and brand lock-in effect, as key considerations in purchase decisions, are stably referenced by the model in Q6 and Q7.

Cluster Structure:

The overall framework of the seven horizontal clusters remains relatively stable, though cluster boundaries exhibit some ambiguity. Oclean appears across multiple clusters simultaneously, while usmile shows a degree of drift in its position within the hierarchy and clusters.

Narrative Labels:

Core narrative labels (such as "Clinical Authority" and "Smart Value") are relatively stable, but specific keyword combinations display minor fluctuations as the question framework changes.

Usage Scenario Associations:

The mapping structure between brands and usage scenarios appears clear in Q6, yet scenario boundaries (such as the distinction between "Travel Portability" and "Daily Household Use") show some ambiguity.

Positioning Descriptions:

Positioning category descriptions for each brand exhibit partial overlap between Q3 and Q4, and positioning boundaries are not entirely clear.

Price Perception:

The model explicitly states in Q7 and Q8 that perceptions of price reasonableness for premium brands are being challenged by Chinese brands’ high-specification, low-price strategies, with price perception boundaries undergoing rapid change.

Functional Value Assessment:

The perceived value of intelligent features such as AI brushing guidance, pressure sensors, and app connectivity exhibits significant uncertainty; the model classifies these in the low-to-medium confidence range in Q7.

Brand Rankings:

Brand rankings in regional markets, particularly in China and Southeast Asia, are described by the model as highly volatile, with notable discrepancies across information sources.

Product Model Awareness:

The perceived positioning of specific models, such as the Oral-B iO series and Philips Sonicare DiamondClean series, fluctuates with product iterations; the model has not rendered definitive judgments on the current market standing of individual models.

Cross-Layer Brands:

Oclean appears simultaneously in the third layer (High-End Design Perception) and the fourth layer (Emerging Smart Value Brands) in the model output, illustrating boundary ambiguity across tiers. usmile exhibits a similar positional drift between the fourth and fifth layers.

Cross-Cluster Brands:

Oclean is simultaneously classified under "Smart Technology and Connected Health Brands" (Cluster 2), "Value-Driven Mass Market Brands" (Cluster 4), and "Asian Emerging Innovation Brands" (Cluster 7), representing the most prominent case of cross-cluster boundary ambiguity in the model output.

Unstable Boundaries:

The boundary between "High-End Design Lifestyle Brands" and "Emerging Smart Value Brands" is not clearly defined in the model output, with Laifen's positioning showing minor variations between Q3 and Q4. The boundary between "Specialized Oral Care Brands" and "Mainstream Brand Specialty Product Lines" also exhibits ambiguity.

Framework Dependency:

The model demonstrated a pronounced reliance on the three-tier analytical framework of "Hierarchy-Clustering-Mapping" across all eight Q&A sets. Irrespective of question variations, the model consistently prioritized establishing a hierarchical structure, followed by lateral clustering, and culminating in a two-dimensional mapping, reflecting a clear inclination toward framework templatization.

Label Reuse:

Core labels such as “dentist-recommended”, “clinical credibility”, “sonic technology”, and "value-for-money" were repeatedly reused from Q1 through Q7, exhibiting high cross-question label consistency, though this may also result in excessive simplification of brand differentiation.

Templatization Tendency:

The model produced table outputs with highly similar structures in both Q4 and Q5, revealing a clear structural mapping between positioning categories and narrative themes, indicative of a strong templated output tendency in handling brand perception queries.

Q1 (Hierarchical Classification):

The question explicitly requires "no more than 5–8 levels," and the model generated a structure with exactly seven layers, indicating that the number of levels is clearly constrained by the prompt wording.

Q2 (Horizontal Clustering):

The question requires "5–8 categories," and the model generated seven clusters, with the number of clusters similarly constrained by the prompt boundaries.

Q3 (Two-Dimensional Mapping):

The question provided examples of axes (e.g., technology perception, price perception), and the model selected axis definitions highly similar to the examples, demonstrating dependence on the prompt examples.

Q4 (Positioning Description):

The question explicitly lists four dimensions: "product focus, target users, innovation image, value proposition," and the model's output strictly adheres to these four dimensions, showing strong framework dependence.

Q5 (Narrative Themes):

The question requires "5–8 narrative themes," and the model generated seven themes, with the number constrained by the prompt.

Q6 (Scenario Association):

The question requires organizing the "relationship between brand types and usage scenarios," and the model generated eight categories of scenario mappings, with a complete structure but some overlap in scenario boundaries.

Q7 (Stability Analysis):

The question requires "classification and organization," and the model generated two types of structures: high consistency and high volatility, with clear classification logic, but some judgments lack specific data support.

Q8 (Cognitive Boundaries):

The question requires "classifying and organizing uncertainty factors," and the model generated twelve categories of uncertainties, with fine-grained classification, but some overlap in content between categories.

The audit collection node for this instance was Japan, with the network environment type being a static residential IP.

The model output may have influenced the following aspects: the model's standalone mention in Q7 of "design refinement and hygiene perception" for the Japanese and Asian markets, as well as its relative emphasis in Q3 on "compact products," manifesting as an output tendency associated with the Japanese market context.

It should be noted that no direct causal relationship can be proven between IP geographic location and model output content. The aforementioned phenomena may stem from distributional differences in Japanese market-related content within the training data, or from the model's partial response to geographic context prompts; a more definitive judgment would require comparison data from multiple nodes.

This audit employed the ChatGPT model; however, specific version details were not clearly documented within the data collection environment. Variations in model versions can influence output content, most notably in the assessment of emerging brands (e.g., Laifen, SURI, Bitvae), since the extent of training data coverage for these brands may differ across versions. For any cross-version comparative analyses, it is advisable to record model version information explicitly in future audits.

This audit is based on eight structured question-and-answer sessions with ChatGPT, systematically extracting the model’s organizational framework for perceiving electric toothbrush brands.

From a structural perspective, the model has constructed a seven-tier brand perception hierarchy anchored by Philips Sonicare and Oral-B as dual-core points. This hierarchical structure exhibits high stability across all Q&A sessions. Horizontal clustering, primarily based on brand image and user orientation, generates seven non-hierarchical clusters, representing a semi-stable structure with somewhat fuzzy boundaries. The two-dimensional perceptual mapping, with axes of technological complexity and market accessibility, systematically positions Chinese brands in the “smart value” quadrant, forming a clear perceptual distinction from traditional global brands.

From a narrative perspective, the model exhibits three dominant narrative logics: authority framework, technology framework, and lifestyle framework. Core narrative tags (such as “dentist recommended” and “sonic technology”) are highly stable, though specific narrative language shows slight fluctuations depending on the question framing.

From a stability perspective, brand hierarchy, clinical authority identity tags, and technology anchors constitute stable structures; cluster boundaries, narrative tags, and scenario associations form semi-stable structures; smart feature value judgments, regional brand rankings, and premium reasonableness perceptions constitute high-fluctuation structures.

It should be emphasized that all conclusions in this report describe ChatGPT’s cognitive organization of electric toothbrush brands and do not represent evaluations of actual market performance, brand competitiveness, or consumer preferences.
