Connector Surrounding Wall Protrusion for Outward Force Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors experience deformation and loss of fitting functionality due to outward forces during attachment and detachment, leading to reduced strength and impaired signal transmission.
Innovation Solution
The connector design incorporates a surrounding wall with protrusion or extension portions that contact the board, providing enhanced strength against outward forces by allowing the board to react to these forces, thereby suppressing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the surrounding wall is made thin to reduce size, then the connector size is reduced, but the surrounding wall deforms under outward force during attachment and detachment
Solution Approach 1:
The protrusion portion extends the surrounding wall from the first direction (attachment direction) into the second direction (lateral direction), creating a multi-dimensional support structure. This lateral extension allows the surrounding wall to receive reaction force from the board, preventing deformation without increasing the overall connector footprint in the first direction.
Solution Approach 2:
The protrusion portion is strategically positioned at specific locations on the surrounding wall to provide localized reinforcement. Rather than uniformly thickening the entire surrounding wall, the protrusion portions are placed only where needed to receive reaction force from the board, maintaining overall compactness while providing targeted strength enhancement.
2Quantity of substance
If the surrounding wall is made thin to reduce material usage, then material cost is reduced, but the surrounding wall deforms under outward force
Solution Approach 1:
The protrusion portions provide localized reinforcement only at critical positions where reaction force is needed, rather than uniformly increasing material throughout the entire surrounding wall. This selective reinforcement minimizes additional material usage while effectively preventing deformation at the most vulnerable points.
Solution Approach 2:
The surrounding wall is segmented into multiple functional portions: the main wall body for electromagnetic shielding and the protrusion portions for mechanical support. This segmentation allows each portion to be optimized independently - the main wall remains thin for material efficiency while the protrusion portions provide necessary structural support.
3Strength
If the surrounding wall is reinforced to prevent deformation, then strength is improved, but the connector size increases
Solution Approach 1:
The protrusion portions extend the surrounding wall into the second direction (lateral direction) rather than increasing thickness in the first direction (attachment direction). This dimensional change allows strength enhancement without increasing the overall connector footprint, as the protrusion portions utilize the lateral space above the board.
Solution Approach 2:
The protrusion portions are designed to dynamically interact with the board during attachment and detachment, receiving reaction force only when needed (during prying movements). When not in use, the protrusion portions remain compact, avoiding permanent size increase. The structure adapts its functional configuration based on operational requirements.
