Bus Module Lever Structure for High-Density Connector Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bus modules require high plugging and unplugging forces due to high-density connectors and occupy excessive space, making assembly and disassembly laborious and costly, while maintaining the original blocking piece complicates customization and increases costs.
Innovation Solution
A bus module design featuring a lever structure with a hinge end, operating end, and second bending portion that assists in plugging and unplugging, along with a compact housing configuration that retains the original blocking piece, reducing the overall size and plugging force, and incorporating a lever structure to facilitate easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high-density connectors are used, then connection density is improved, but plugging and unplugging force increases
Solution Approach 1:
A lever structure is introduced as an intermediary mechanical element between the operator and the connector. The lever structure includes a first lever arm hinged to the housing and a second lever arm connected to the first, creating a mechanical advantage system that reduces the force required to plug and unplug high-density connectors while maintaining connection density
2Stability of the object's composition
If an L-shaped blocking piece is used, then structural stability is improved, but housing space increases
Solution Approach 1:
The blocking piece is redesigned from a two-dimensional L-shaped structure to a three-dimensional structure that utilizes vertical space within the housing. By extending the blocking piece in the vertical dimension and positioning it to work with the lever structure, the same structural stability is achieved while reducing the horizontal footprint and overall housing volume
3Ease of operation
If lever structure is added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The lever structure is segmented into distinct functional components: a first lever arm hinged to the housing, a second lever arm connected to the first, and associated biasing elements. This segmentation allows each component to be optimized independently while maintaining overall simplicity, making the assembly easier to operate without proportionally increasing complexity
