Electric Striker Unit Dual Connector Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric striker units face challenges in installation, particularly in limited spaces, due to conventional screw-type connectors that complicate electrical cable connection, limiting flexibility and ease of use.
Innovation Solution
The electric striker unit features two distinct types of electrical connectors arranged on different housing walls, allowing for easier access and connection, even in narrow spaces, with a detection system to ensure safe functionality by disconnecting unused connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-type connectors are used for electrical connection, then reliable electrical contact is achieved, but installation complexity increases and ease of operation deteriorates in limited spaces
Solution Approach 1:
The electrical connection system is segmented into multiple connector types (screw-type and tool-free) positioned at different locations, allowing selection of the most appropriate connector for each installation scenario, thus resolving the contradiction between reliability and ease of operation
Solution Approach 2:
A detection system acts as an intermediary between the connectors and the control unit, automatically identifying which connector is connected and enabling the control unit to adjust its operation accordingly, ensuring reliable functionality regardless of which connector type is used
2Adaptability or versatility
If multiple electrical connectors are provided on different housing walls, then adaptability to different installation situations is improved, but device complexity increases
Solution Approach 1:
The electric striker unit is designed with multiple electrical connectors of different types on different housing walls, each capable of performing the same electrical connection function but suited for different installation scenarios, thereby achieving universality and resolving the contradiction between adaptability and complexity
Solution Approach 2:
The detection system provides feedback to the control unit about which connector is connected, enabling the system to automatically adapt its operation, thus managing the complexity through intelligent control rather than mechanical complexity
3Area of stationary object
If limited space is available around the striker unit, then installation space constraint is worsened, but the ability to connect electrical cables deteriorates
Solution Approach 1:
Electrical connectors are positioned on different housing walls (different spatial dimensions), allowing cable access from multiple directions, thus resolving the contradiction between limited installation space and cable connection ease by utilizing three-dimensional space efficiently
