Peripheral Cord Lock for Secure Cable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for securing peripheral cables to computers, such as screws, are complex, expensive, and unsuitable for small form factor cables like USB connectors, leading to disconnection issues, especially in portable devices.
Innovation Solution
A locking connector with a compliant grip and shell that securely interfaces with cable ends, using a screw or adhesive for attachment, and optionally a flange for additional stability, allowing for secure connection without adding bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to secure cable ends to computers, then connection stability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The locking connector is divided into distinct functional segments: a rigid shell providing structural support and mounting interfaces, a compliant grip providing secure cable engagement, and optional adhesive members for alternative attachment. This segmentation allows each component to be optimized independently while simplifying overall manufacturing.
Solution Approach 2:
The locking connector serves as an intermediary device between the cable end and the computer port. It provides the securing function that would otherwise require modification of the cable or computer, thereby simplifying the overall system while improving connection reliability.
2Reliability
If screws are used to secure cable ends, then connection stability is improved, but manufacturing cost increases
Solution Approach 1:
The locking connector is designed as an affordable, easily manufactured component that can be produced in high volumes using standard molding techniques for the shell and grip. This approach makes the securing function accessible for consumer electronics without requiring expensive specialized hardware.
Solution Approach 2:
The design allows for parameter variations in materials (rigid vs. compliant), attachment methods (screw, adhesive, or friction-fit), and geometry to optimize for different manufacturing capabilities and cost targets while maintaining the core securing function.
3Reliability
If locking mechanisms are added to small form factor cables, then connection stability is improved, but the cable becomes too bulky
Solution Approach 1:
The compliant grip is nested within the rigid shell, with the cable end inserted through the shell and gripped by the compliant material. This nested arrangement provides secure locking while maintaining a compact overall form factor suitable for small cables like USB connectors.
Solution Approach 2:
The compliant grip uses flexible, thin-walled material that can deform to grip the cable end securely without adding significant bulk. The flexibility allows the grip to conform to the cable geometry while providing adequate securing force in a minimal volume.

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 solution provides a secure, reliable, and adaptable means to connect various cable types to computers, resisting disconnection and accommodating different port configurations, while maintaining ease of use and reducing complexity and cost.
Implementation Method 1
one embodiment of the present invention employs an adhesive member or members for situations where the electronic device does not employ a threaded hole adjacent to the port
Implementation Method 2
The flange creates a surface that frictionally engages the surface surrounding the port that is configured to receive the connector end
Data Source
AI summary
A device is provided adapted to firmly connect a cable end to a computer or similar electronic device. The device selectively receives and secures a cable end by way of an interference fit. The device is then interconnected to the computer, for example, with adhesives or a screw so that unintended disconnection of the cable is prevented.
