Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed mapping table is embedded in the visor controller at the factory, then product stability is ensured, but the visor cannot adapt to different user preferences and environmental conditions

Engineering Contradiction:

Improveproduct stabilityVSAvoidadaptation to user preferences and environmental conditions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the static mapping table into a dynamic one by enabling real-time adjustments based on user feedback and environmental conditions. The controller continuously learns from user manual adjustments and automatically updates the mapping relationship between illuminance and transmittance, allowing the system to adapt while maintaining operational stability through controlled modification rules.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements self-learning functionality where the visor automatically observes user manual adjustment behaviors and environmental data, then autonomously optimizes the mapping table without requiring explicit user programming. The controller accumulates adjustment patterns over time and automatically generates optimized transmittance settings, enabling the system to serve itself in adapting to user preferences.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If users are allowed to manually adjust transmittance settings, then user preferences can be accommodated, but users must repeatedly adjust the visor after each start-up

Engineering Contradiction:

Improveuser preference accommodationVSAvoidrepeated manual adjustment time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary learning during the initial usage period by monitoring user manual adjustments and environmental conditions. It accumulates sufficient adjustment data and pre-computes optimized mapping relationships before normal operation begins, so that when the learning phase completes, the visor has already prepared personalized settings that eliminate the need for repeated user adjustments.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements a feedback loop where user manual adjustments are continuously monitored and fed back to the controller. The controller analyzes these feedback signals, identifies user preferences and patterns, and automatically updates the mapping table accordingly. This closed-loop feedback mechanism allows the system to learn from user behavior and automatically adapt, eliminating the need for repeated adjustments.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the mapping table is optimized for high-latitude regions with strong light, then performance in those regions improves, but the original mapping relationship cannot be changed without affecting product stability

Engineering Contradiction:

Improveperformance in high-latitude regionsVSAvoidproduct stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent enables dynamic parameter changes in the mapping table by allowing the controller to modify the relationship between illuminance and transmittance based on detected environmental conditions and user preferences. The system adjusts key parameters such as transmittance thresholds and mapping curves while maintaining the overall structural integrity of the control logic, thus adapting to different regional conditions without compromising system stability.

Inventive Principle:

Principle #35Parameter changes

AI summary

The present invention discloses a method for automatically adjusting a visor transmittance mapping relationship based on a user habit, where a virtual brightness mapping table is preset, each adjustment instruction of a user is recorded, and a brightness control target under current ambient illuminance is calculated based on the instruction, and is used to automatically modify transmittance in a mapping control table. Users in different regions can constantly correct the transmittance in the mapping control table according to the ambient illuminance at the current moment during use, until calibration of the visor is in a steady state, which reduces a subsequent adjustment operation of the users, without affecting stability of a product.
