Grip Heater Wiring Structure Using Engaging Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wiring structure of grip heaters does not accommodate an accelerator position sensor, leading to potential interference and failure to house the feeder cable, which can result in size and weight inefficiencies.
Innovation Solution
A wiring structure that includes an engaging section between the grip pulley and accelerator position sensor, allowing the feeder cable to be wound on the outer circumference of this section, with a guide-out section and locking mechanism to prevent interference and enable housing within a case, while maintaining a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the feeder cable is routed to be wound around an accelerator pulley, then the cable routing is achieved, but the routing space interferes with the engaging section and the cable cannot be housed in the case
Solution Approach 1:
The patent changes the winding location from the accelerator pulley to the engaging section, which is positioned in a different spatial dimension. The engaging section is located at the outer circumference of the accelerator position sensor, allowing the cable to be routed along the grip rotation direction without interfering with the accelerator pulley area. This dimensional relocation resolves the space interference problem while maintaining cable routing functionality.
2Reliability
If an engaging section is added to engage the grip pulley with the accelerator position sensor, then the sensor function is achieved, but the device complexity increases
Solution Approach 1:
The engaging section serves multiple functions simultaneously: it engages the grip pulley with the accelerator position sensor to transmit rotational information, and it provides a winding surface for the feeder cable. By combining these functions into a single structural element, the patent avoids increasing overall device complexity while achieving reliable sensor engagement and proper cable routing.
3Volume of moving object
If the feeder cable is wound on the outer circumference of the engaging section, then the cable can be housed in the case, but the engaging section occupies additional space
Solution Approach 1:
The patent implements a nested arrangement where the feeder cable is wound around the outer circumference of the engaging section, effectively nesting the cable within the spatial envelope of the engaging section. This allows the cable to be contained within the case without requiring additional external routing space, as the cable path is integrated into the existing engaging section geometry.
