Wall-Mount Connector Rib Structure for Tolerance-Free Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors experience looseness and dimensional inaccuracies due to high dimensional tolerance in the opening of the case, leading to instability and potential scratching, necessitating a solution for stable attachment without looseness, size reduction, simplified structure, reduced components, and lower costs.
Innovation Solution
The connector features a housing with elastic members and terminals, including ribs on the side walls that contact the inner surface of the opening, providing a secure fit and locking mechanism to prevent looseness, while maintaining a simplified structure and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional connector is used with a case opening having high dimensional tolerance, then the connector can be easily installed, but the connector experiences looseness and instability
Solution Approach 1:
The elastic members are designed with specific material properties and geometric parameters (thickness, length, rib configurations) that enable them to adapt to dimensional variations in the opening while maintaining stable attachment. The elastic modulus and cross-sectional dimensions are optimized to provide appropriate flexibility and locking force.
Solution Approach 2:
The elastic members provide dynamic adaptation to the opening dimensions through their deformable nature. They can elastically deform during insertion to accommodate tolerance variations, then maintain a stable locked state, transitioning from a flexible insertion phase to a rigid attached state.
2Reliability
If elastic members with ribs are added to the connector, then attachment stability is improved, but device complexity increases
Solution Approach 1:
The elastic members integrate multiple functions into a single component: they provide attachment force through their elastic properties, positioning through their geometric shape, and locking through the ribs that engage with the opening inner surface. This merging eliminates the need for separate locking mechanisms or adjustment components.
Solution Approach 2:
The elastic members are positioned at multiple locations (front, rear, left, right sides) of the connector housing, creating segmented attachment points that distribute the locking force and provide stable attachment through coordinated action of multiple identical simple structures.
3Reliability
If multiple elastic members are used to prevent looseness, then attachment reliability is improved, but manufacturing cost increases
Solution Approach 1:
The attachment system uses multiple identical elastic members positioned at different locations (front, rear, left, right sides) of the connector. Each member has the same simple structure with ribs, allowing for standardized mass production and reducing per-unit cost through economies of scale.
Solution Approach 2:
All elastic members are designed with identical geometry, material properties, and rib configurations. This homogeneity simplifies the manufacturing process by requiring only one tooling set and one quality control specification, reducing overall manufacturing complexity and cost despite using multiple members.
