Sliding Module Locking Mechanism for Portable Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding modules in portable electronic devices face issues with the push rod disengaging from the upper groove when sliding to close, leading to unstable sliding and increased force requirements, and protruding thresholds can hinder smooth operation.
Innovation Solution
A sliding module with a locking member that selectively blocks the push rod on the support member, allowing it to remain engaged with the upper groove during sliding, and a reduced protrusion design for smoother operation, incorporating a locking member on the push rod and support member to stabilize the sliding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a threshold protrudes between the upper groove and lower groove to guide the sliding housing, then the push rod can be guided during sliding, but the sliding housing cannot slide smoothly and may not slide at all depending on the protruding state
Solution Approach 1:
The support member is divided into an upper groove portion and a lower groove portion with a reduced protrusion threshold between them. This segmentation allows the push rod to be guided through the upper groove while the reduced threshold minimizes interference during sliding transitions, resolving the contradiction between guiding function and sliding smoothness
Solution Approach 2:
The protrusion width of the threshold is changed from a conventional larger dimension to a specifically reduced dimension. This parameter change allows the threshold to provide necessary guiding function while minimizing its interference with the sliding housing, enabling both reliable guidance and smooth operation
2Power
If the first engaging portion rotates on the upper groove during closing, then the push rod can provide elastic force, but the first engaging portion may slide from the upper groove due to push force
Solution Approach 1:
A locking member is introduced as an intermediary element between the first engaging portion and the upper groove. This locking member prevents the first engaging portion from sliding off the upper groove while allowing it to rotate and provide elastic force, thus resolving the contradiction between power provision and engaging stability
Solution Approach 2:
The locking member is positioned in advance to prevent potential disengagement of the first engaging portion from the upper groove before it can occur. This preliminary protective action ensures that the engaging portion remains stable while performing its power-providing rotation

Function Achieved in This Case
Enables stable and smooth bi-directional sliding of the housing by preventing disengagement of the push rod and reducing the protrusion width, enhancing the operational efficiency of the sliding mechanism in portable electronic devices.

AI summary
A sliding module includes a main housing; a sliding housing on the main housing, a push rod interposed between the main housing and the sliding housing to provide an elastic force to slide the sliding housing, a support member mounted on the main housing and rotatably or slidably coupled with the push rod, and a locking member disposed on the push rod and the support member. The locking member blocks the push rod to limit the sliding of the push rod on the support member and allows the push rod to slide when the push rod rotates on the support member according to the sliding of the sliding housing.
