Fixation Clip Web Tensioning for Line Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixation clips fail to securely hold lines, such as cables, under high pull-out forces, as the swivel arms can pivot out of the receptacle against the swivel direction, leading to loss of line fixation.
Innovation Solution
Incorporating a web with a joint that attaches to the swivel arm and frame, which stretches and tensions to prevent swivel arm movement out of the holding position, combined with protrusions and supporting tabs to enhance line retention and accommodate various line sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If swivel arms are used to enable easy assembly of the line, then ease of operation is improved, but reliability deteriorates because swivel arms can pivot out under high pull-out forces
Solution Approach 1:
A web element is introduced as an intermediary between the swivel arm and the frame. This web acts as a mediator that allows the swivel arm to pivot freely during assembly while preventing the arm from pivoting back outward under load, thus resolving the contradiction between ease of assembly and fixation reliability
Solution Approach 2:
The swivel arm mechanism is made dynamic by allowing it to pivot freely during the assembly phase, then transitioning to a locked state during the fixation phase. The web element enables this dynamic behavior by permitting movement in one direction (assembly) while restricting movement in the opposite direction (disassembly under load)
2Reliability
If the web is made rigid to prevent swivel arm movement, then reliability is improved, but ease of operation deteriorates because the swivel arm cannot pivot into the assembly position
Solution Approach 1:
The web is designed with dynamic characteristics that allow it to be flexible during the assembly phase (permitting swivel arm pivoting) and rigid during the fixation phase (preventing outward movement). This is achieved through the web's geometric configuration that allows folding during assembly but stretching/tensioning during fixation
3Device complexity
If the frame structure is simplified, then device complexity is reduced, but reliability deteriorates because additional components are needed to prevent swivel arm movement
Solution Approach 1:
The web element is merged with the existing frame and swivel arm structure rather than being a completely separate component. The web utilizes the existing geometric features of the frame and swivel arm, combining multiple functions (positioning, locking, and guiding) into a single integrated element that does not significantly increase overall device complexity
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 solution ensures reliable line fixation by preventing swivel arm movement out of the holding position, even under high pull-out forces, while allowing easy assembly and accommodating larger lines through adjustable design elements.
Implementation Method 1
During such movement the web is stretched or subjected to tension and thus reliably holds the swivel arm in the holding position
Implementation Method 2
when pivoting the swivel arm into the assembly position the web can easily be folded together, so that when pivoting the swivel arm into the assembly position the web provides no resistance and in addition can be folded in a space-saving manner
