Bicycle Switch Designation Apparatus for Ergonomic Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle shift control devices have fixed upshift and downshift switch arrangements, which do not accommodate individual rider preferences for switch orientation, requiring complex rewiring or mounting upside down to change the arrangement.
Innovation Solution
A switch designation apparatus that allows users to selectively designate the upshift and downshift operations of bicycle control devices using a switch designation unit, enabling the reconfiguration of switch functions without rewiring or upside-down mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the switch arrangement is fixed in conventional shift control devices, then the device structure is simple and manufacturing is easy, but the adaptability to different rider preferences is poor
Solution Approach 1:
The patent applies dynamics by making the switch control functions programmable and changeable through software rather than fixed hardware. The control unit can dynamically reassign which switch performs upshift or downshift functions, allowing the same physical device to adapt to different rider preferences without structural changes.
Solution Approach 2:
The patent changes the operational parameters of the switches through software configuration. By modifying the control unit's programming, the functional assignment of switches can be altered without changing their physical positions or electrical wiring, enabling different riders to customize their preferred switch orientations.
2Ease of operation
If the switch arrangement is reversed to accommodate rider preference, then the ergonomics are improved, but the device requires complex rewiring or mounting upside down
Solution Approach 1:
The patent replaces the mechanical approach of physically repositioning or rewiring switches with an electronic/software solution. The control unit's programmable nature allows functional reassignment through software configuration rather than mechanical modification, eliminating the need for complex rewiring or upside-down mounting.
Solution Approach 2:
The control unit is designed with universal functionality to handle multiple switch configurations. A single control unit can serve different riders with different preferences by programmatically assigning different functions to the same physical switches, making the device multi-functional without requiring multiple specialized units.
3Adaptability or versatility
If the switch arrangement is fixed with upshift above downshift, then the manufacturing process is simple, but it does not accommodate riders who prefer downshift above upshift
Solution Approach 1:
The patent implements preliminary action by providing a user interface that allows riders to pre-configure their preferred switch arrangements before riding. The control unit stores multiple switch configuration profiles, and riders can select their preferred configuration in advance, eliminating the need for time-consuming rewiring or physical repositioning when changing preferences.

AI summary
A switch designation apparatus for a bicycle control unit comprises a first switch structured to be mounted to a bicycle for providing signals to move a moving bicycle control device, a second switch structured to be mounted to the bicycle for providing signals to move the moving bicycle control device, and a switch designation unit that allows a user to selectively designate movements of the bicycle control device signaled by at least one of the first switch and the second switch.
