Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological signal detection technologies face issues with heat dissipation and maintainability due to radars being built into seats, leading to poor performance and difficulty in repair or replacement.
Innovation Solution
The biological signal detection apparatus is integrated into the buckle of a seat belt, utilizing an antenna circuitry for electromagnetic wave emission and reception, and a module circuitry for signal detection, enhancing heat dissipation and maintainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the radar is built into the seat back, then it does not give a sense of foreign matter to the seated person, but it has poor heat dissipation property
Solution Approach 1:
The radar is extracted from the seat back and relocated to the seat belt buckle. This separation removes the radar from the enclosed seat back structure, allowing for better heat dissipation while maintaining unobtrusive operation. The radar in the buckle can dissipate heat to the surrounding air without being trapped in the seat back's confined space.
2Reliability
If the radar is built into the seat back, then it provides stable detection, but it is not easily detachable during repair or replacement
Solution Approach 1:
The radar detection system is segmented into separate functional components distributed between the seat belt buckle and the control unit. The radar itself is housed in the removable buckle, while signal processing occurs in the control unit. This segmentation allows the radar to be easily detached and replaced by simply removing the buckle, while maintaining stable detection through the distributed architecture.
3Duration of action of stationary object
If the radar is built into the seat back, then it provides continuous detection, but it has poor maintainability
Solution Approach 1:
The seat belt buckle serves as an intermediary carrier for the radar, allowing it to be easily removed and replaced. The buckle acts as a mediator between the radar and the vehicle's electrical system, enabling maintenance personnel to quickly swap the radar unit by simply detaching the buckle without complex disassembly, thus maintaining both continuous detection capability and ease of repair.
