Elastic Fixation Clip for Trusswork Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trusswork structures face challenges when additional structures are affixed, as conventional clips concentrate forces in small areas, compromising structural integrity and creating unsightly protrusions.
Innovation Solution
A fixation clip made from elastic material with a central bore and guiding notch, allowing for elastic deformation to distribute forces homogeneously and integrate seamlessly into the trusswork structure, avoiding external protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional clips are used to attach additional structures to the trusswork structure, then the additional structures can be connected, but forces are concentrated in a small area of the knot, compromising structural integrity
Solution Approach 1:
The fixation clip is divided into multiple functional segments: a body portion that interfaces with the trusswork knot, a fixation element that engages additional structures, and elastic deformation zones that distribute forces. This segmentation allows each part to perform its specific function while collectively distributing loads across the entire trusswork structure rather than concentrating them at a single point.
Solution Approach 2:
The fixation clip incorporates localized elastic properties in specific regions (the body portion and engagement surfaces) while maintaining rigidity in other areas. This local quality variation enables the clip to deform elastically under load to distribute forces homogeneously across the trusswork bars, while still providing firm mechanical engagement with both the trusswork structure and additional structures.
2Ease of manufacture
If conventional clips are used to attach additional structures, then connection is achieved, but the clips stick out from the trusswork structure forming disturbing contours
Solution Approach 1:
The fixation clip is designed to nest within the existing trusswork structure geometry. The body portion fits into the knot space between bars, and the overall profile is contoured to follow the external surface of the trusswork. This nesting approach allows the fixation means to be integrated into the lattice structure without creating protruding contours that would disturb the aerodynamic or aesthetic appearance.
Solution Approach 2:
The fixation clip utilizes the third dimension by extending primarily in the direction perpendicular to the trusswork surface, with a compact profile that minimizes protrusion. The elastic deformation capability allows the clip to adapt its shape in multiple dimensions, conforming to the trusswork geometry while maintaining secure engagement, thus eliminating disturbing contours from multiple viewing angles.
3Strength
If rigid fixation means are used, then structural strength is maintained, but thermally or abrasively induced geometric changes in the lattice structure cannot be compensated
Solution Approach 1:
The fixation clip transitions from a static rigid connection to a dynamic adaptive connection. The elastic body portion can deform in response to changing geometric conditions caused by thermal expansion or abrasive wear of the trusswork bars. This dynamic capability allows the fixation means to maintain optimal engagement and force distribution even as the lattice structure undergoes dimensional changes during operation.
Solution Approach 2:
The fixation clip's elastic properties allow its physical parameters (shape, volume, engagement forces) to change in response to environmental conditions. As the trusswork structure experiences thermal variations or abrasion, the fixation clip's elastic deformation zones adjust its geometry and contact pressures, maintaining constant structural integrity and compensation capability throughout the operational lifecycle.
