Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long driving can lead to neck, back, and shoulder pain due to stressful driving posture and sitting positions, with existing technologies not effectively addressing the need for a convenient and effective stretching exercise solution for vehicle passengers.
Innovation Solution
A control device that uses light as a visual aid to guide passengers through stretching exercises by sequentially illuminating predefined locations, determining the correctness of stretching movements, and providing immediate feedback through visual, haptic, or audio cues, integrated with vehicle systems like LED lights, cameras, and sensors to ensure proper execution of the exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a stretching exercise system is implemented in a vehicle, then passenger comfort and health are improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical exercise equipment with a lighting-based guidance system. Instead of using mechanical devices to physically assist stretching, the system uses light sources to visually guide passengers through exercises, significantly reducing mechanical complexity while maintaining health benefits
Solution Approach 2:
The patent introduces light as an intermediary between the control device and the passenger. The light sources serve as a mediator to communicate exercise instructions and provide visual feedback, eliminating the need for direct mechanical interaction while still guiding the stretching exercise effectively
2Measurement precision
If visual feedback is provided to guide stretching movements, then exercise precision is improved, but device complexity increases
Solution Approach 1:
The patent uses different light colors to indicate exercise execution status. Green light indicates correct execution, yellow indicates partial execution, and red indicates incorrect execution. This color-coded feedback system provides precise guidance while keeping the control logic relatively simple and intuitive
Solution Approach 2:
The patent implements a feedback mechanism where the control device receives data from sensors about passenger position and controls light sources to provide real-time visual feedback. This closed-loop system continuously monitors and guides stretching movements, improving precision through iterative visual cues
