Leaf Spring Fastening Element for Quick Cable Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening elements for cables or lines are not designed for quick and easy assembly and disassembly, making it difficult to fix and reassign the position of cables in cable harnesses, especially when plugs are removed.
Innovation Solution
A fastening element with a receptacle featuring a support area, a holding element, and a locking element designed like a leaf spring, along with a release device that includes a release projection for easy release, allowing for quick detachment and reassignment of cables, and adjustable latching elements for secure fixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fastening elements are used, then cables can be fixed in position, but assembly and disassembly are time-consuming and difficult
Solution Approach 1:
The locking element is designed as a spring-loaded mechanism that can dynamically transition between locked and unlocked states. The spring force automatically engages the locking element with the holding element upon insertion, and the release device allows quick disengagement by overcoming the spring force, enabling rapid assembly and disassembly operations
Solution Approach 2:
The locking element automatically engages with the holding element through spring force when the cable is inserted, without requiring manual intervention for locking. The system self-locks upon insertion, eliminating the need for separate locking operations and reducing assembly time
2Reliability
If secure locking is provided, then cable position is reliably fixed, but release mechanism becomes complex
Solution Approach 1:
The release device acts as an intermediary mechanism that simplifies the release operation. Instead of directly manipulating the spring-loaded locking element, the release device translates a simple user action (pressing the release projection) into the necessary force to overcome spring force and disengage the locking element, maintaining reliability while reducing operational complexity
Solution Approach 2:
The fastening element is segmented into distinct functional components: the locking element for secure engagement, the holding element for cable retention, and the release device for easy disengagement. This segmentation allows each component to be optimized for its specific function, with the release device being a simple addition that doesn't complicate the overall structure
3Productivity
If quick release is enabled, then disassembly is fast, but locking reliability may be compromised
Solution Approach 1:
The spring-loaded locking element provides strong automatic engagement for reliable locking during normal operation. The same spring mechanism, when acted upon by the release device, enables quick disengagement. The dynamic nature of the spring force allows the system to provide both strong locking and quick release capabilities without compromising either function
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
Enables rapid assembly and disassembly of cables, ensuring accurate positioning and easy reassignment of plugs to slots, while providing reliable fixation and easy release mechanisms, suitable for applications like automotive and electronics.
Implementation Method 1
The locking element (18) is designed like a leaf spring and can interact with the holding element (16) in such a way that it is fixed in a position holding the cable or line (24)
Implementation Method 2
The release device enables the locking element to be easily released from the retaining element, so that the retaining element can be released easily and quickly. The locking element is designed like a leaf spring so that it can be easily released by deforming or pivoting the locking element.
