Saddle-Type Vehicle Handle Switch Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycles without an advancing-backing function are unable to utilize handle switches efficiently due to the need for a dedicated backing mode setting switch, leading to increased switch numbers and decreased layout efficiency.
Innovation Solution
A saddle-type vehicle with a handle switch featuring a backing-enabled mode setting input part and a control system that disables transmission shift operations, allowing the vehicle to advance or back using existing shift switches, eliminating the need for a dedicated switch and enhancing layout efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated backing mode setting switch is provided, then backing function can be achieved, but the number of switches increases and layout efficiency decreases
Solution Approach 1:
The shift switches are designed to serve dual purposes: in normal mode they control transmission shifting, and in backing-enabled mode they control advancing and backing operations. The control system detects the mode and reassigns the function of the shift switches accordingly, eliminating the need for dedicated backing switches while maintaining full functionality.
2Adaptability or versatility
If a dedicated backing mode setting switch is provided, then backing function can be achieved, but switch layout efficiency is lowered
Solution Approach 1:
The existing shift switches on the handlebar are made multi-functional by implementing mode-based function switching. When backing-enabled mode is detected, the same physical switches that normally control gear shifting are repurposed to control advancing and backing, maintaining intuitive operation without requiring additional switches or complex layout changes.
3Device complexity
If shift switches are used for both transmission shifting and advancing-backing control, then common use is achieved, but operation confusion may occur
Solution Approach 1:
The function of the shift switches dynamically changes based on the detected operating mode. The control system monitors the mode state and automatically reassigns the switch functions: in normal mode the switches control transmission gear changes, while in backing-enabled mode they control advancing and backing. This dynamic reassignment prevents operation confusion by ensuring the switches always perform their intended function without requiring the user to mentally switch contexts.

AI summary
A saddle-type vehicle that allows common use of a handle switch with a vehicle having no advancing-backing function and can suppress increase in the number of switches and the lowering of the layout efficiency of the switches. A saddle-type vehicle has a reverse mode setting input part that sets a reverse mode in which backing driving of the saddle-type vehicle is permitted and a control system that disables shift operation of a transmission by a shift-down switch and a shift-up switch and causes the saddle-type vehicle to advance through operation of the shift-down switch and to back through operation of the shift-up switch when the reverse mode is set.
