Rotary Motion Structure with Elastic Member for Automatic Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary motion structures lack a mechanism for automatic ejection and positioning, making them inconvenient for applications such as board or circuit board placement without specialized designs.
Innovation Solution
A rotary motion structure comprising a limiting member and a rotating member with an elastic member, where the rotating member is rotatably provided on the limiting member, and includes a shaft portion, limiting portions, and an elastic member that allows for automatic positioning and ejection by compressing and expanding to fix or release the rotating member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no special design is provided for board or circuit board placement, then the device structure remains simple, but the convenience of placement is poor
Solution Approach 1:
The rotary member is pre-equipped with positioning protrusions and the limiting member has corresponding positioning recesses, so that when the rotary member rotates to the correct position, the positioning features automatically engage to guide and secure the board or circuit board placement without requiring additional alignment operations
Solution Approach 2:
The elastic member automatically pushes the rotary member to rotate and the positioning features self-lock when engaged, enabling the placement mechanism to perform its function automatically once activated, eliminating the need for complex control systems or manual intervention
2Extent of automation
If the elastic member is added to enable automatic positioning and ejection, then the automation function is improved, but the device complexity increases
Solution Approach 1:
The rotary member serves multiple functions: it acts as both the rotating actuator and the positioning element, while the elastic member simultaneously provides both the driving force for rotation and the ejection force, reducing the need for separate components for each function
Solution Approach 2:
The positioning protrusions and recesses are integrated directly into the rotary member and limiting member structures respectively, merging the positioning function with the existing rotational mechanism rather than adding separate positioning systems

AI summary
A rotary motion structure comprises a limiting member and a rotating member. The limiting member defines a mounting portion; and the rotating member is rotatably provided on the limiting member and includes a shaft portion, which is provided through the mounting portion. Accordingly, the rotary motion structure described above is preferably applied to form a handle device having a positioning function, in which the rotating member is rotated relative to the limiting member so that the rotating member can have the positioning efficacy of automatic positioning, frictional positioning, temporary positioning, or fixed positioning.
