Shift Carrier Path Switching for Simpler Position Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shift devices have complex configurations for changing the shift position of a shift member, which can be cumbersome and inefficient.
Innovation Solution
A shift device with plural movement paths and a changing mechanism that simplifies the configuration by allowing the moving portion to be relatively displaced to change the movement path, thereby altering the shift position of the shift member, and includes a regulation portion to bias the shift member towards its position.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple stop bolts are provided to change the crank segment, then the shift position can be changed, but the device complexity increases
Solution Approach 1:
The movement path is divided into multiple distinct paths (first movement path, second movement path, etc.), each corresponding to a different shift position. The moving portion transitions between these segmented paths to achieve position changes, replacing the need for multiple stop bolts with a cleaner segmented path structure.
Solution Approach 2:
The invention extracts and eliminates the stop bolt component from the system. Instead of using stop bolts to define and change the crank segment position, the movement paths themselves are designed to inherently guide the moving portion to the correct positions, removing the need for separate stopping mechanisms.
2Adaptability or versatility
If a complex changing mechanism is used to change the movement path, then the shift position can be changed, but the ease of manufacture decreases
Solution Approach 1:
The moving portion is designed to dynamically transition between different movement paths based on the shift operation. The paths are structured to naturally guide the moving portion through its range of motion, eliminating the need for complex active changing mechanisms and simplifying manufacturing.

AI summary
In a shift device, a changing mechanism displaces a carrier to thereby change a rotation stratum in which the carrier is disposed and change rotation paths with which detent pins of the carrier are engaged. For this reason, to change the rotation paths with which the detent pins are engaged, the changing mechanism needs only to displace the carrier, and so the configuration of the changing mechanism can be simplified.
