Flexible Strap Fixturing with Rigid Locking Teeth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixturing systems for cables lack a secure mechanism to prevent accidental disengagement, as they rely on flexible loop-type and hook-type fasteners that do not provide sufficient locking force to maintain the attachment of cables in place.
Innovation Solution
A fixturing apparatus kit that includes a housing with an aperture and a flexible strap, where the strap is secured by a plurality of rigid locking teeth that prevent backward movement unless an unlocking key is used, ensuring the strap remains firmly in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible loop-type and hook-type fasteners are used to attach cables, then the attachment can be easily installed and removed, but the locking force is insufficient to prevent accidental disengagement
Solution Approach 1:
The fastening system is divided into separate components: a flexible strap for easy insertion, rigid locking teeth for secure engagement, and an unlocking key for controlled release. This segmentation allows each component to perform its specific function optimally while resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
An unlocking key is introduced as an intermediary tool to release the locking mechanism. This mediator enables controlled disengagement without requiring excessive force or complex maneuvers, maintaining both security during normal operation and ease of removal when needed.
2Reliability
If rigid locking teeth are added to prevent backward movement, then the security and locking force are improved, but the device complexity increases
Solution Approach 1:
The locking teeth are integrated directly into the housing structure, merging the locking mechanism with the main body of the device. This reduces the number of separate components and simplifies assembly while maintaining the security function against backward movement.
Solution Approach 2:
The flexible strap automatically engages with the locking teeth upon insertion, creating a self-locking mechanism that secures itself without requiring additional tools or complex operations. The design leverages the natural properties of the materials to achieve secure fastening.
3Reliability
If an unlocking key mechanism is implemented, then the control over strap removal is improved, but the ease of operation is reduced
Solution Approach 1:
The unlocking key is designed as a simple, inexpensive tool that can be easily manufactured and distributed. Its simplicity ensures that while it provides controlled access to the locking mechanism, it does not significantly complicate the removal process for end users.
