Vehicle Shift Device Bidirectional Movement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shift devices for vehicles can only rotate the operation element in one direction, limiting the ability to change the shift position in both directions effectively.
Innovation Solution
A shift device with a moving mechanism that includes a moving member with first and second moving portions, allowing the shift body to be moved in both directions, and an urging member with releasing portions to manage the load and interference, enabling rotation in both directions without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single moving portion is used to rotate the operation element, then the structure is simple, but the operation element can only rotate in one direction
Solution Approach 1:
The moving member is divided into a first moving portion and a second moving portion that are disposed apart from each other. The first moving portion rotates the operation element in a first direction, while the second moving portion rotates it in a second direction. This segmentation allows bidirectional rotation capability while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the moving member is positioned to enable bidirectional movement, then both directions of shift body movement are enabled, but interference between components may occur
Solution Approach 1:
A releasing portion is provided on the moving member that performs preliminary action by releasing the urging force from the urging member before the shift body moves in a predetermined direction. This prevents interference between the shift body and the moving portions during bidirectional movement, as the releasing portion disengages the urging member in advance before directional movement occurs.
3Reliability
If the urging member continuously urges the shift body, then the shift body returns to initial position reliably, but interference occurs during bidirectional movement
Solution Approach 1:
The urging member's action is made dynamic through the releasing portion mechanism. The releasing portion selectively releases the urging force from the urging member based on the movement direction. When the shift body needs to move in a specific direction, the releasing portion disengages the urging member, allowing movement without interference. When return to initial position is needed, the urging member's force is restored. This dynamic control maintains reliability while preventing interference.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the shift body to be moved in both directions efficiently, reducing load application and interference, and allows for early-stage movement in each direction, enhancing the shift device's operational range and reliability.
Implementation Method 1
an urging member that urges the shift body; a first releasing portion that is provided at the moving member, and that, in a case in which the first moving portion moves the shift body in the first direction, releases urging of the shift body by the urging member

AI summary
A shift device for a vehicle includes: a shift body that is moved in a predetermined range in a first direction and in a second direction that is a direction opposite from the first direction, and whose shift position is changed; and a moving mechanism that has a moving member at which a first moving portion and a second moving portion are provided, the first moving portion moving the shift body in the first direction, and the second moving portion moving the shift body in the second direction, due to movement of the moving member.
