Pivotable Cable Holder for Rail Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable fastening devices are inflexible and require complex adjustments when cable routes change, especially in curved sections or varying tunnel heights, necessitating rigid substructures that are difficult to adapt.
Innovation Solution
A device featuring a pivotable intermediate piece with a cable clamp part and rail part, allowing for adjustable fastening via cable clamp bolts and rail bolts, enabling horizontal and vertical adjustments through eccentric pivot axes and slotted holes for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid substructures are used for cable fastening, then structural stability is improved, but adaptability to cable route changes deteriorates
Solution Approach 1:
The intermediate piece is designed with a pivot joint that allows it to rotate between a transport position (parallel to mounting rail) and a working position (perpendicular to mounting rail). This dynamic capability enables the rigid structure to adapt to different cable routing scenarios while maintaining structural stability during each operational state.
Solution Approach 2:
The fastening device is divided into distinct functional segments: the mounting rail, the pivotable intermediate piece, and the cable clamp. This segmentation allows the intermediate piece to independently rotate and adjust, providing adaptability without compromising the stability of the overall structure.
2Adaptability or versatility
If adjustment elements are added to adapt substructure to cable route changes, then adaptability is improved, but device complexity increases
Solution Approach 1:
Instead of adding multiple complex adjustment mechanisms, the invention uses a single pivot joint that provides rotational adjustment capability. This simple dynamic element allows the intermediate piece to orient itself appropriately for different cable routes without increasing overall device complexity.
Solution Approach 2:
Rather than attempting to bend or flex the rigid mounting rail to accommodate cable route changes, the invention inverts the approach by keeping the rail fixed and rotating the intermediate piece to achieve the necessary adaptation.
3Reliability
If multiple fastening points are used to secure the intermediate piece, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The pivot joint incorporates a detachable connection mechanism that allows the intermediate piece to be easily released and repositioned. When fastened, multiple connection points ensure reliability; when adjusted, the detachable nature enables easy operation by allowing the intermediate piece to be temporarily disengaged and re-engaged at different positions.
