Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a base is designed to provide only charging function, then the device structure is simple, but the user understanding of brushing habits is limited

Engineering Contradiction:
Improveusage data communicationVSAvoidbase structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The base is designed to perform multiple functions: inductive charging through the charging component, wireless communication through the Bluetooth component, real-time data processing through the analyzing component, and visual feedback through the light component. This multi-functional design allows the base to serve as both a charging device and a comprehensive data communication hub, resolving the contradiction between providing complete usage information and maintaining simple device structure

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The base acts as an intermediary device between the toothbrush and the user. It receives usage data from the toothbrush via Bluetooth, processes the data in real-time through the analyzing component, and communicates the processed information back to the user through light signals. This intermediary role enables comprehensive usage monitoring without requiring complex processing in the toothbrush itself or direct complex interaction between the user and toothbrush data

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If real-time data processing is implemented, then user feedback is immediate, but energy consumption increases

Engineering Contradiction:
Improvereal-time usage feedbackVSAvoidbase energy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The analyzing component processes usage data in real-time as it is received from the toothbrush during brushing sessions. The light component provides visual feedback that corresponds to the processed data, creating a periodic feedback loop that occurs naturally during the brushing activity. This approach enables immediate user feedback without requiring continuous high-energy processing, as the processing is triggered by and synchronized with the periodic nature of brushing sessions

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The base utilizes the power outlet for energy supply, and the system automatically processes and communicates usage data without requiring additional user intervention. The Bluetooth component automatically establishes communication with the toothbrush, the analyzing component automatically processes the received data, and the light component automatically provides visual feedback. This self-service operation minimizes energy-wasting manual operations while maintaining real-time feedback capability

Inventive Principle:
Principle #25Self-service
