Rotary Switching Device Axial Mirror Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary switching devices are difficult to operate when viewed from the axial direction, especially when selection elements are irregularly arranged, making it impossible for operators to recognize which selection elements can be switched at specific positions.
Innovation Solution
A rotary switching device with a cylindrical first member featuring a mirror surface that reflects information displayed on its outer circumferential surface, allowing visual recognition from the axial direction, and an indicating part to identify selected elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If selection elements are arranged irregularly or can be switched to other selection elements, then the device can provide more flexible switching options, but the operator can no longer recognize which selection element can be selected at which position
Solution Approach 1:
A mirror surface part is introduced as an intermediary element that reflects light from the circumferential surface to the axial direction. This mirror surface acts as a mediator between the irregularly arranged selection elements and the operator's view, enabling the operator to see which selection element is currently selectable by reflecting its position and identification information into the axial viewing direction.
Solution Approach 2:
The patent transforms the viewing dimension from purely circumferential to axial by using the mirror surface to redirect light. Instead of requiring the operator to view the device from the side (circumferential direction), the mirror surface projects the selection element information into the axial dimension, allowing recognition from the front view while maintaining irregular arrangement flexibility.
2Ease of operation
If selection elements are regularly arranged, then the operator can select a desired selection element by sequentially performing a rotation operation, but the device cannot accommodate irregular arrangements or dynamic switching options
Solution Approach 1:
The mirror surface part serves as a real-time indicator that shows which selection element will be selected upon rotation. This intermediary feedback mechanism allows the operator to perform sequential rotation operations with clear visual guidance, while the system can simultaneously support irregular arrangements and dynamic switching options without compromising ease of operation.
3Loss of information
If information is displayed on the circumferential surface, then the operator can recognize selection elements when viewing from the circumferential side, but the operator cannot visually recognize information when viewing from the axial direction
Solution Approach 1:
The patent solves the visibility problem by using the mirror surface to project circumferential surface information into the axial viewing dimension. The mirror surface reflects light carrying selection element identification and position information from the circumferential direction to the axial direction, enabling operators to view and operate the device from the axial side with full visual recognition capability.
4Illumination intensity
If the device is operated from the axial direction, then the operator has a clear view of the device front, but the operator cannot recognize selection elements that are displayed on the circumferential surface
Solution Approach 1:
The mirror surface part acts as an optical intermediary that captures light reflected from the circumferential surface (where selection element information is displayed) and redirects it toward the axial viewing direction. This creates a virtual image of the selection elements visible to operators viewing from the axial direction, maintaining visual recognition clarity while enabling axial operation.
