Cable Holding Member Design for Crack Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cables with connectors for electronic devices are prone to cracking and breakage due to frequent bending and lack a secure locking mechanism, leading to connector disconnection when the device is dropped.
Innovation Solution
A cable design featuring a flexible holding member that surrounds the connector and electric wires, with a shape that decreases in width to distribute force evenly and includes a protrusion or spring elements for enhanced stability, along with a locking member on the cover case to secure the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional cable connector is frequently bent for connection and disconnection, then the connector can be easily operated, but the sheath develops cracks and the cable breaks
Solution Approach 1:
The holding member is divided into a rigid portion and a flexible portion, allowing the cable to bend at the flexible portion while the rigid portion maintains structural integrity and protects the connector during frequent connection and disconnection operations
Solution Approach 2:
The holding member with its flexible portion absorbs and cushions the stress from frequent bending and external forces before they can reach the sheath and connector, preventing crack development and maintaining reliability
2Ease of operation
If the connector protrudes from the electronic device for easy access, then the connector is easily operable, but it becomes vulnerable to leverage forces causing deformation
Solution Approach 1:
The holding member is designed to extend along the connector and provide support before external leverage forces are applied, preventing deformation by distributing the force along the holding member's length rather than concentrating it at the connector
3Ease of operation
If no locking mechanism is provided to allow easy connection, then the cable can be quickly connected, but the connector comes off when the device is dropped
Solution Approach 1:
The holding member applies a preliminary securing action to the connector, creating friction and mechanical engagement that prevents the connector from dislodging during accidental drops, while still allowing easy manual connection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cable provides a robust and secure connection that prevents deformation and disconnection, even under external forces, reducing the likelihood of cracking and breakage, and maintains connectivity during accidental drops.
Implementation Method 1
a spring element which is helically wound around the electric wires enclosed in the holding member
Implementation Method 2
a locking member that locks the electric wires is provided on an outer side of the cover case
