Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cables in electronic equipment are prone to movement relative to securing clamps during severe impacts, leading to loose connectors and unreliable signal transmission due to inadequate axial security.
Innovation Solution
A cable securing clamp with a clamp body and snap member, featuring a first through hole for the cable and a second through hole with a tooth structure for interference fit, ensuring three-dimensional securement of the cable, preventing axial and radial movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional clamp with upper and lower casings is used to secure the cable radially, then the cable is secured in the radial direction, but the cable is prone to move along the axial direction during severe impacts
Solution Approach 1:
The invention transitions from two-dimensional radial securing (using only upper and lower casings) to three-dimensional securing by adding axial constraint through a snap member. The snap member extends along the axial direction and includes a limiting portion that contacts the cable to prevent axial movement, thereby completing the three-dimensional confinement of the cable within the clamp.
Solution Approach 2:
The clamp body is divided into functionally distinct segments: the upper and lower casings that provide radial securing, and the separately installed snap member that provides axial constraint. This segmentation allows each component to be optimized for its specific function and enables modular assembly and maintenance.
2Device complexity
If the cable is allowed to move axially, then the clamp structure remains simple, but the connector becomes loose and signal transmission reliability is influenced
Solution Approach 1:
The solution adds axial constraint functionality to the otherwise simple radial clamp structure by introducing a snap member that extends in the axial direction. This additional dimensional constraint prevents cable movement along the axial axis while maintaining relative simplicity through the snap-fit installation method of the snap member.
3Reliability
If a snap member with tooth structure is added to secure the cable axially, then the cable is secured in both radial and axial directions, but the clamp structure becomes more complex
Solution Approach 1:
The snap member is designed with a pivotally connected first end that allows it to be dynamically inserted and secured into the clamp body. The snap member can be flexibly installed by pivoting it into the clamp body and then locked in place through interference fit, providing a dynamic installation process that simplifies assembly despite the added structural complexity.
Solution Approach 2:
The snap member is nested within the clamp body structure, with its second end extending into the clamp body and being received by the clamp body's internal features. This nesting arrangement integrates the snap member into the existing clamp structure without requiring separate mounting fixtures or additional external components.
