Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for cable carriers require increased assembly effort and precise tolerance matching between cable carriers and support devices, with limited adaptability to different side rail geometries, especially in terms of height and width.
Innovation Solution
A fastening clip with a bending section that can be bent over the upper end of the cable carrier's side wall during assembly, allowing adaptation to various side wall geometries, featuring a support section that engages with the carrying device and a bending section that is designed to transmit tensile forces while being plastically deformed for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening systems with C-shaped or U-shaped brackets are used, then the cable carrier can be attached to the support structure, but the assembly effort increases and precise tolerances are required
Solution Approach 1:
The fastening clip is divided into functionally distinct sections: a support section for engaging the support device and a bending section for securing to the cable carrier side rail. This segmentation allows each part to perform its specific function optimally, with the support section providing stable mounting and the bending section enabling simple plastic deformation for attachment.
Solution Approach 2:
The fastening clip utilizes plastic deformation of the bending section to change its shape permanently during assembly, transforming it from a straight configuration to a bent configuration that secures the cable carrier. This parameter change eliminates the need for elastic restoration forces and complex adjustment mechanisms.
2Reliability
If traditional fastening elements are used, then attachment is achieved, but adaptability to different side rail geometries is limited
Solution Approach 1:
The bending section is designed to accommodate different side rail geometries by varying the bend angle and position during assembly. The plastic deformation allows the same fastening clip design to adapt to different heights and widths of cable carrier side rails without requiring multiple specialized components.
Solution Approach 2:
The fastening clip is designed as a universal component that can attach to various cable carrier geometries through the adaptable bending section. The support section provides consistent engagement with the support device while the bending section adjusts to different side rail configurations, making the same clip design applicable across multiple applications.
3Reliability
If precise tolerance matching is required between cable carriers and support devices, then secure attachment is achieved, but the device complexity increases
Solution Approach 1:
The plastic deformation of the bending section absorbs dimensional variations and tolerance deviations between the support device and cable carrier side rail. By allowing permanent shape change during assembly, the system accommodates a wider range of dimensions without requiring precise pre-matching of components.
Solution Approach 2:
The fastening function is extracted from a rigid, precision-matched connection and transferred to a plastic deformation process. This separates the support function (handled by the support section with standard tolerances) from the securing function (handled by the bending section through plastic deformation), reducing overall tolerance requirements.
