Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing displacement detection systems for industrial equipment, such as vehicles, are complex, prone to external damage, and suffer from reduced accuracy due to external forces and environmental exposure, leading to increased costs and potential degradation.
Innovation Solution
A displacement detection device comprising a coil spring, a rotating member, and a detection device integrated with a bearing, which allows for the detection of the coil spring's rotation without the need for a link mechanism, reducing the number of components and exposure to external elements, while maintaining accuracy through a simple and lightweight configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a link mechanism is used to detect displacement, then the detection function is achieved, but the device complexity increases and the detection device is exposed to external elements causing damage and reduced accuracy
Solution Approach 1:
The detection device is integrated directly with the coil spring structure, merging the detection function into the existing component. This eliminates the need for separate link mechanisms and reduces the number of exposed parts, thereby improving reliability while reducing device complexity
Solution Approach 2:
The detection device is extracted from the external environment by integrating it within the coil spring assembly, removing it from exposure to external elements that cause damage and accuracy degradation
2Reliability
If additional fixing mechanisms are added to protect the detection device, then durability is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The fixing function is merged into the coil spring assembly structure itself, which naturally protects the integrated detection device without requiring additional external fixing mechanisms, thereby maintaining durability while reducing manufacturing complexity and cost
