Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for cables are costly and complex, requiring multiple parts and assembly steps, which affect the laying rate and accuracy of cable routes due to introduced stresses and additional manufacturing steps.
Innovation Solution
A fastening device comprising two clips with retaining ribs that engage around cables in a force-fitting manner, combined with a guide element and retaining element for secure mounting, allowing for easy and reliable cable fixation with defined orientation, and featuring a design that allows relative movement along the curvature of the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid fixing means are used to fix cables, then the cables can be secured in position, but the fixing means require multiple parts and assembly steps which increase complexity and cost
Solution Approach 1:
The patent combines multiple fixing functions into a single integrated clip structure. The clip includes an interlocking closure mechanism that integrates the cable retention function and the mounting function into one piece, eliminating the need for separate fixing components and reducing assembly steps while maintaining reliable cable fixation.
Solution Approach 2:
The clip is designed as a multi-functional component that simultaneously performs cable securing, positioning, and mounting to the main structure. The interlocking closure mechanism provides both cable retention and structural attachment capabilities in a single element, reducing overall system complexity.
2Adaptability or versatility
If separate fixing means are used for each cable type and situation, then specific cable requirements can be met, but the variety of parts increases manufacturing complexity and expense
Solution Approach 1:
The clip design incorporates adjustable and adaptable features that allow a single fixing means to accommodate different cable types and mounting situations. The interlocking closure mechanism can adapt to various cable diameters and configurations, eliminating the need for multiple specialized fixing components.
Solution Approach 2:
The clip structure allows for parameter adjustments in terms of cable accommodation through its flexible yet secure interlocking mechanism. The design can adapt to different cable sizes and configurations by utilizing the same basic structure with variable engagement parameters, rather than requiring different fixed designs for each cable type.
3Manufacturing precision
If axial orientation of fixing means is performed during assembly to follow the route accurately, then route accuracy is improved, but assembly expenditure and time increase significantly
Solution Approach 1:
The clip is pre-designed with built-in orientation guidance features and a self-aligning interlocking closure mechanism that automatically orients itself correctly during installation. This preliminary design consideration eliminates the need for time-consuming axial orientation adjustments during assembly, while still achieving accurate cable routing.
Solution Approach 2:
The fixing means incorporates self-aligning and self-orienting characteristics through its interlocking closure design. The mechanism automatically positions itself in the correct orientation during installation without requiring manual adjustment or complex alignment procedures, thereby maintaining route accuracy while reducing assembly time.
4Reliability
If bearing points are fitted in separate manufacturing processes like injection-molding or shrink-fitting, then cable fixation reliability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The bearing points and fixation features are integrated into a single clip structure that can be manufactured as one piece. This merging of functions eliminates the need for separate bearing point installation processes such as injection-molding or shrink-fitting, while maintaining reliable cable fixation through the unified interlocking closure mechanism.
