Flexible Pressure Lever for Compact Cable Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking devices for electrical lines have a high overall height due to clamps, making them unsuitable for installations with limited space, and they often fail to accommodate lines of different diameters effectively.
Innovation Solution
The marking device features a flexible pressure lever with a pressure piece and obtuse-angled receptacle prisms, allowing for a reduced overall height and adaptability to various line diameters, with a film hinge for latching and a recess for elastic deformation, ensuring secure locking without high forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamps are used to form the cable holder, then the marking device can securely hold electrical lines, but the overall height becomes relatively large, requiring more installation space
Solution Approach 1:
The pressure lever is designed as a flexible, elastically deformable component that can dynamically adapt to different line diameters and installation conditions. This flexibility allows the marking device to achieve secure holding without requiring a large overall height, as the pressure lever can deform to accommodate various configurations rather than requiring a fixed, height-consuming clamp structure
Solution Approach 2:
The pressure lever is made from a flexible material that can elastically deform during the clamping process. This flexible design replaces the rigid clamp structure, enabling the marking device to achieve reliable line holding while maintaining a compact overall height that fits in cramped installation spaces
2Adaptability or versatility
If the pressure lever is made flexible to accommodate different line diameters, then adaptability improves, but the pressure force may be insufficient for secure clamping
Solution Approach 1:
The pressure lever is designed with a curved or bent geometry that provides mechanical advantage. When the pressure lever is pressed against the electrical line, its curved shape allows it to exert sufficient pressure force while remaining flexible enough to adapt to different line diameters. The curvature enables the lever to store and release elastic energy, maintaining consistent clamping force across various installation conditions
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 design achieves a lower overall height and secure attachment to electrical lines of different diameters, reducing installation space requirements and ensuring stable fixation without requiring excessive force.
Implementation Method 1
the pressure lever is fixed by means of a hinge in the form of a film hinge on a transverse edge of the support plate
Implementation Method 2
the pressure lever is provided with a recess in areas adjoining the pressure piece, at least on one long side, so that the width compared to the end areas is reduced. So that the pressure lever is sufficiently deformable for the elastic deformation with regard to the different diameters of the electrical lines
