Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors with conductive elastic members and frames face issues with unexpected deformation and potential breakage due to strain, leading to increased thickness and reduced effectiveness in connecting with connection targets like circuit boards.
Innovation Solution
A connector design featuring an inner frame that holds the conductive elastic member for vertical connection and an outer frame that allows the inner frame to move perpendicular to the vertical direction, with engagement portions to regulate movement, reducing the overall thickness and preventing deformation-induced breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If an outer frame with a structure for holding the inner frame is added, then the connector can establish electric connection with low load, but the thickness of the entire connector becomes large
Solution Approach 1:
The inner frame is nested within the outer frame, with the inner frame positioned inside the outer frame's internal space. This nesting arrangement allows both frames to coexist without significantly increasing the overall thickness, while the outer frame provides the necessary structure to hold the inner frame and enable low-load electric connection
2Reliability
If the inner frame is made movable in the perpendicular direction, then the conductive elastic member is protected from breakage, but the structure complexity increases
Solution Approach 1:
The inner frame is designed to be movable relative to the outer frame in the perpendicular direction (lateral movement), allowing it to dynamically adjust its position to absorb strain and deformation. This dynamic capability protects the conductive elastic member from breakage without requiring complex additional components, as the movement itself provides the protective function
3Stability of the object's composition
If engagement portions are added to regulate movement, then the inner frame movement is controlled, but the manufacturing complexity increases
Solution Approach 1:
The engagement portions are integrated directly into the inner frame and outer frame structures themselves, combining the movement regulation function with the existing frame components. The inner frame includes engagement portions that interact with corresponding features on the outer frame, providing movement control without requiring separate regulatory components, thus avoiding increased manufacturing complexity
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
The design effectively reduces the connector's thickness while ensuring stable connections by allowing the inner frame to move in the perpendicular direction, absorbing stress and preventing the conductive elastic member from breaking, thus maintaining connectivity with connection targets.
Implementation Method 1
the conductive elastic member may be deformed unexpectedly by strain of the frame
Implementation Method 2
the inner frame is movable along a movable direction perpendicular to the vertical direction

AI summary
A connector has a conductive elastic member, an inner frame configured to hold the conductive elastic member so that the conductive elastic member is connectable with connection targets in a vertical direction, and an outer frame configured to hold the inner frame so that the inner frame is movable along a movable direction perpendicular to the vertical direction. An inner frame engagement portion is provided on an outside surface of the inner frame. An outer frame engagement portion is provided on an inside surface of the outer frame. The inner frame engagement portion and the outer frame engagement portion are engaged with each other so as to regulate a relative movement of the inner frame in the vertical direction and to permit a relative movement of the inner frame in the movable direction.
