Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection devices for relative position between movable elements are often complex, unsightly, and increase the cost of the structure due to the need for attachment to the elements being monitored.
Innovation Solution
A detection device integrated into one of the elements, where the relative position is detected by an electrical circuit that opens and closes based on the position of the elements, utilizing conductive parts within the circuit to transmit information without external attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detection device is attached to the elements being monitored, then the relative position can be detected, but the structure becomes more complex, unsightly, and expensive
Solution Approach 1:
The patent merges the detection device with one of the elements being monitored (either the movable element or the fixed element) by integrating conductive parts directly into the element's structure. This eliminates the need for separate attachment components, thereby reducing structural complexity while maintaining detection capability. The conductive parts become part of the element itself rather than external attachments.
Solution Approach 2:
The element being monitored serves dual functions: it performs its primary mechanical function (e.g., moving, supporting) and simultaneously serves as part of the detection circuit through its conductive parts. This multi-functionality reduces the need for separate detection components, simplifying the overall structure while enabling position detection.
2Reliability
If a detection device is attached to the elements being monitored, then the relative position can be detected, but the appearance becomes unsightly
Solution Approach 1:
By integrating the conductive detection parts directly into the element's structure rather than attaching separate detection devices, the patent eliminates visible external components. The detection functionality becomes invisible or indistinguishable from the element itself, preserving aesthetic appearance while maintaining detection capability.
3Reliability
If a detection device is attached to the elements being monitored, then the relative position can be detected, but the cost increases
Solution Approach 1:
The patent combines the detection functionality with the existing elements, eliminating the need for separate detection device components and their associated manufacturing and assembly costs. The conductive parts are integrated into the element's structure, reducing material costs and simplifying manufacturing processes.
Solution Approach 2:
The element serves multiple functions (mechanical function + detection function), which reduces the total number of components needed in the system. This consolidation reduces manufacturing costs by eliminating the need to produce and assemble separate detection devices.
