C-Shaped Cable Holding Device with Movable Wing for Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for tubes or cables in automotive brackets rely on elasticity for attachment, which is insufficient to prevent slippage due to vibrations or mounting imprecision.
Innovation Solution
A plastic holding device with a C-shaped seat and movable wing that locks the cable or tube in place through a snap mechanism, utilizing elastic deformation to secure the attachment portion within the bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an elastic attachment portion is used to hold a tube or cable in a bracket, then the device is simple to manufacture and install, but the tube or cable can slip out due to vibrations or mounting imprecision
Solution Approach 1:
The holding device is divided into two functional parts: a C-shaped seat for initial elastic engagement and a movable wing for locking. This segmentation allows the device to combine simple elastic insertion with secure locking, resolving the contradiction between ease of manufacture and reliability.
Solution Approach 2:
The C-shaped seat performs preliminary elastic engagement to guide and initially secure the attachment portion. This preliminary action prepares the system for the subsequent locking action of the wing, ensuring both simple installation and reliable prevention of slippage.
2Reliability
If a locking mechanism is added to prevent slippage, then reliability is improved, but device complexity increases
Solution Approach 1:
The wing is designed as a movable component that can be easily positioned to engage with the attachment portion. This dynamic element provides the locking function needed for reliability while maintaining simplicity through its straightforward movement and engagement mechanism.
Solution Approach 2:
The holding device utilizes elastic deformation of the C-shaped seat and flexible engagement surfaces to achieve secure holding. This approach provides reliable locking through elastic forces rather than complex mechanical joints, reducing overall device complexity.
3Ease of operation
If a through passage seat is used for radial insertion, then ease of operation is improved, but the attachment portion can deform excessively during insertion
Solution Approach 1:
The insertion path is segmented into two stages: first through the open C-shaped seat which allows easy radial insertion, then through the narrowing defined by the wing which controls final positioning. This segmentation enables both ease of operation and control of deformation.
Solution Approach 2:
The C-shaped seat performs preliminary engagement to guide the attachment portion into correct alignment before final securing. This preliminary guidance prevents excessive deformation during insertion while maintaining ease of radial access.
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 device effectively prevents the cable or tube from slipping out of the bracket, ensuring reliable attachment and easy installation, while being simple to manufacture and fit.
Implementation Method 1
Said attachment portion elastically deforms while it enters the bracket and then goes back to its original shape after having completely engaged the seat

AI summary
A holding device to hold a tube or cable in engagement with a bracket is provided with a structure having a seat, which is a through seat along an axis and is defined by a substantially C-shaped edge so as to have a radial opening; the structure further has a slit, which extends along a radial direction up to said seat so as to allow the bracket, in use, to be inserted into the slit and engage the seat; the holding device is further provided with a wing, which is movable between an open position, in which the seat can be accessed through the opening and a closed configuration, in which the opening is closed by the wing.
