Straddle Vehicle Controller with Lower Rotary Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straddle type vehicle operation devices face challenges in maintaining operability and discrimination of switches within an existing switch box, particularly in operating multiple functions like selecting and determining function menus without confusing them with other switches.
Innovation Solution
A controller with a rotary shaft positioned lower than the switch box's lower wall face and extending parallel to it, allowing for easy operation with one finger while maintaining the operability of multiple switches, and a supporting portion that accommodates electronic components, enabling compact configuration and efficient use of space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dial-type operation ring is attached to the inner side of the grip, then the rider can operate equipment, but the finger needs to stretch over the operation ring making controller operation difficult
Solution Approach 1:
The controller operation portion is extracted from the switch box and repositioned to the lower side of the grip, allowing it to be operated independently without interfering with other switches. This separation resolves the contradiction by removing the operation ring structure that caused stretching difficulties while maintaining equipment operation capability.
Solution Approach 2:
The controller operation portion is positioned in a different spatial dimension (lower side of the grip) rather than on the inner side of the grip. This dimensional change allows the rider to operate the controller without stretching the finger over the grip, eliminating the operational difficulty while preserving the ability to access equipment functions.
2Ease of operation
If a rotary controller is provided in the switch box, then function menu selection is facilitated, but the switch box is enlarged and freedom in arrangement is limited
Solution Approach 1:
The controller operation portion is extracted from the switch box and positioned separately on the lower side of the grip. This extraction maintains the rotary control functionality for easy function menu selection while preventing the switch box from being enlarged, as the controller occupies no additional space within the switch box itself.
Solution Approach 2:
The controller is relocated to a different spatial location (lower side of the grip) rather than being embedded in the switch box. This dimensional relocation preserves the compact switch box area while providing easy access to function menu selection through the rotary operation portion positioned in the new location.
3Ease of operation
If a switch protruding from the switch box is used, then discrimination from other switches is improved, but multiple functions like selection and determination cannot be operated with a single controller
Solution Approach 1:
The controller operation portion is designed with multi-functionality, incorporating both rotary operation for function menu selection and pressing operation for determination. This universal design allows a single controller to perform multiple functions (selection and determination) that were previously requiring separate switches, while the protruding structure maintains clear discrimination from other switches.
Solution Approach 2:
The selection and determination functions are merged into a single controller operation portion. The rotary motion enables function menu selection while the pressing motion enables determination, combining what were previously separate switch operations into one unified controller that protrudes from the switch box for easy discrimination.
4Ease of operation
If the controller operation portion is positioned on the lower side of the grip, then operability is maintained and discrimination is facilitated, but the controller structure becomes more complex
Solution Approach 1:
The controller is segmented into distinct functional components: the operation portion that protrudes for discrimination and operation, the rotary shaft for rotation detection, and the supporting portion for structural support. This segmentation allows each component to be optimized independently, maintaining ease of operation while managing structural complexity through modular design.
Solution Approach 2:
The controller structure employs nesting, where the operation portion is positioned on the lower side of the grip, the rotary shaft is arranged inside the operation portion, and the supporting portion provides structural foundation. This nested arrangement consolidates multiple components into a compact configuration, maintaining operability while reducing overall structural complexity compared to separate distributed components.

AI summary
An operation device of a straddle type vehicle has a controller used to operate at least two or more kinds of functions of equipment mounted on the straddle type vehicle. The controller includes a controller operation portion capable of rotary and other freely moving operations. A rotary shaft of the controller inside the controller operation portion is arranged lower than a lower wall face of a switch box.
