Vehicle Light-Adjusting System with Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle light-adjusting systems require occupants to perform complex operations or use limited contact methods, making it difficult to adjust light transmittance freely, especially when movement is restricted, and do not allow for flexible adjustment of light transmission regions.
Innovation Solution
A vehicle light-adjusting system with a light-adjusting member divided into multiple parts, an instruction detecting unit that can recognize gestures and voice commands, and a control unit that adjusts transmittance accordingly, allowing for non-contact and flexible selection of adjustment areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact-based operation methods are used for light adjustment, then the system can detect instructions reliably, but the ease of operation deteriorates when movement is restricted
Solution Approach 1:
The patent replaces mechanical contact-based operation with non-contact gesture recognition and voice command systems. The gesture recognition unit detects hand movements and gestures in the air without requiring physical contact with the device, while the voice recognition unit captures verbal instructions. This substitution eliminates the need for precise finger movements, making the system operable even when the user's hands are occupied or movement is restricted by seat belts.
2Adaptability or versatility
If the light-adjusting member is divided into multiple parts with individual transmittance control, then the adaptability improves for selective adjustment, but the device complexity increases
Solution Approach 1:
The light-adjusting member is divided into multiple independent parts (first light-adjusting part and second light-adjusting part) that can be controlled separately. Each part has its own transmittance control capability, allowing independent adjustment of different regions of the windshield. The control unit receives instructions and selectively adjusts only the specified part's transmittance, enabling flexible regional control without requiring complete system redesign.
3Device complexity
If only width adjustment from a fixed end is implemented, then the control method remains simple, but the adaptability for free position adjustment is limited
Solution Approach 1:
The system transitions from a static control method with a fixed reference end to a dynamic control method where either end of the light-adjusting member can be designated as the reference. The control unit determines the reference end based on the user's instruction direction - if the instruction specifies adjustment from the near end, the near end becomes the reference; if from the far end, the far end becomes the reference. This dynamic adaptability allows free position adjustment while maintaining relatively simple control logic.

AI summary
A vehicle light-adjusting system includes a light-adjusting member arranged in an incident portion into which an external light enters, a control unit that controls transmittance of the light-adjusting member, and an instruction detecting unit. The light-adjusting member is divided into a plurality of parts. The instruction detecting unit detects an instruction given by the occupant in a non-contact manner to the light-adjusting member by at least one of gesture and words. When the instruction detecting unit detects the instruction designating any one of the parts, the control unit adjusts an individual transmittance of the part corresponding to the instruction detected by the instruction detecting unit.
