Solution Overview
Problem
Existing electrical connections, particularly those using Zero-Insertion-Force (ZIF) connectors, suffer from low reliability and ease of disconnection, leading to unintentional interruption of electrical contact.
Innovation Solution
A cable receiving device with a stiffening element and a resilient retaining element that provides a form-fitting connection, allowing for secure locking of the cable end without the need for a traditional connector, ensuring reliable and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Zero-Insertion-Force connectors are used for cable connections, then ease of connection is improved, but connection reliability deteriorates due to low release force causing unintentional disconnection
Solution Approach 1:
The resilient retaining element provides a dynamic locking mechanism that automatically engages when the cable is inserted and requires deliberate action to release. The element deformable in the insertion direction creates a one-way locking action that maintains secure connection while allowing easy insertion, resolving the contradiction between ease of connection and connection reliability.
2Reliability
If a traditional connector is used on the cable end, then connection reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention extracts the connector from the cable end and places it only in the receiving device. The cable end remains simple with just conductors and insulation, while the receiving device contains the resilient retaining element and insertion direction control. This extraction reduces cable complexity and manufacturing cost while maintaining connection reliability through the receiving device's locking mechanism.
Solution Approach 2:
The receiving device serves multiple functions: it provides the locking mechanism through the resilient retaining element, guides insertion through the defined insertion direction, and establishes electrical contact. By consolidating these functions in the receiving device rather than requiring a complex connector on the cable, the overall system complexity is reduced while maintaining reliability.
3Ease of manufacture
If the cable end structure is simplified without a connector, then manufacturing cost is reduced, but connection security deteriorates
Solution Approach 1:
The resilient retaining element acts as an intermediary between the simple cable end and the receiving device. It provides the necessary locking and securing functions without requiring a complex connector on the cable. The element deforms during insertion to create a secure mechanical interlock, ensuring connection security while keeping the cable end structure simple and inexpensive to manufacture.
