Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interior lighting devices with tactile control interfaces face challenges in compactness, manufacturing cost, and precision due to mounting requirements and exposure to vehicle vibrations, which compromise sensor accuracy, especially for curved profiles.
Innovation Solution
The tactile control interface is directly mounted on the mounting support via sensor means, which also detect deformations, allowing for improved compactness and reduced manufacturing costs while enhancing contact detection precision through capacitive or resistive sensors and a controller that processes deformation data to control light sources based on contact area and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the plate is mounted via mounting means on a mounting support, then the device achieves structural stability, but the compactness of the device is reduced and manufacturing cost increases
Solution Approach 1:
The patent combines the mounting function and sensing function into a single integrated sensor means. The sensor means serves dual purposes: mounting the touch interface plate on the mounting support and detecting contact deformations. This eliminates the need for separate mounting means, thereby improving compactness while maintaining structural stability.
Solution Approach 2:
The sensor means is designed to perform multiple functions simultaneously: it acts as both a mounting mechanism and a contact detection device. By making the sensor means universal, the patent reduces the number of components needed, improving compactness without sacrificing the structural stability required for reliable operation.
2Ease of manufacture
If the plate is mounted via separate mounting means, then the assembly is easier to manufacture, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the mounting function and sensing function into a single integrated sensor means. This reduces the total number of components that need to be manufactured and assembled, thereby simplifying the manufacturing process while maintaining ease of assembly through the integrated design.
Solution Approach 2:
The sensor means is designed to perform multiple functions simultaneously: mounting and contact detection. This multi-functionality reduces the number of separate manufacturing steps and assembly operations required, simplifying the overall manufacturing process while maintaining ease of assembly.
3Adaptability or versatility
If the plate is subjected to vehicle vibrations and jolts, then the device operates in realistic vehicle conditions, but the precision of contact detection is compromised
Solution Approach 1:
The sensor means acts as an intermediary between the touch interface plate and the mounting support. It detects deformations of the plate while being mounted on the support, allowing the system to distinguish between deformations caused by contact and those caused by vehicle vibrations. This intermediary role enables precise contact detection even in realistic vehicle conditions.
Solution Approach 2:
The sensor means provides feedback on the deformation state of the touch interface plate. By continuously monitoring deformations and comparing them against threshold values or patterns, the system can distinguish between contact-induced deformations and those caused by vehicle vibrations, maintaining high precision in contact detection under realistic operating conditions.
