Rectangular Fir Tree Mount for Anti-Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting solutions for bundled elongate articles, such as wires and cables, fail to provide a secure and anti-rotational grip on supporting surfaces, often leading to issues like noise and electronic failure due to vibration and abrasion, and require multiple fasteners or complex configurations for stability.
Innovation Solution
A rectangular fir tree mount assembly with flexible springs and branches that securely attach to a supporting surface, providing tension and resistance, and can be integrated with a wire connector or other attachment mechanisms to stabilize bundled items with a single mounting hole, ensuring anti-rotation and reduced insertion force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting solutions are used to secure bundled items, then the items can be attached to a support surface, but the mounting does not provide sufficient resistance and tightness against the support surface, leading to inadequate support under vibration and jostling
Solution Approach 1:
The mounting element is divided into multiple functional segments: a mounting shaft for insertion, multiple resilient arms with gripping elements for securing, and a rotation-resistant mechanism. This segmentation allows each component to perform its specific function optimally, providing both securing reliability and grip strength simultaneously.
Solution Approach 2:
The resilient arms are designed to be flexible and dynamic, allowing them to deflect during insertion and then spring back to engage the backside of the support surface. This dynamic behavior enables the mounting to adapt to variations in panel thickness while maintaining strong gripping force and reliability.
2Stability of the object's composition
If traditional mounting solutions are used, then attachment is possible, but they do not provide anti-rotation capability or require multiple mounting shafts to prevent rotation
Solution Approach 1:
The resilient arms are arranged in an asymmetric pattern around the mounting shaft, with arms positioned at different angles and lengths. This asymmetric configuration provides inherent anti-rotation capability, as the distribution of gripping forces creates a stabilizing moment that prevents rotational movement while maintaining structural simplicity.
Solution Approach 2:
The anti-rotation function is merged into the same mounting element that provides securing capability. The resilient arms serve dual purposes: gripping the bundled items and providing rotation resistance through their strategic positioning and engagement with the support surface, eliminating the need for separate anti-rotation components.
3Reliability
If stronger mounting studs are used to improve grip, then securing reliability increases, but the mounting requires longer insertion length and is not easily inserted into the support surface
Solution Approach 1:
The resilient arms are designed to be flexible during insertion, allowing them to deflect and pass through the aperture in the support surface without requiring excessive insertion force. Once inserted, the arms spring back to their original position, engaging the backside of the support surface to provide strong gripping force. This dynamic behavior enables easy insertion while maintaining high mounting reliability.
Solution Approach 2:
The mounting element utilizes elastic deformation as a key parameter change mechanism. During insertion, the resilient arms are compressed or bent beyond their neutral position, storing elastic energy. Upon engagement with the support surface, the arms return to their neutral or extended position, converting stored elastic energy into gripping force, thereby achieving both easy insertion and strong retention.
4Ease of manufacture
If wire connectors are left dangling to allow flexibility, then installation is simple, but the wire connector is free to move about causing noise or electronic circuitry failure due to wire abrasion or wire fatigue
Solution Approach 1:
The mounting element is designed as a universal solution that can secure wire connectors, cable bundles, hoses, or other elongate articles. By providing a stable mounting point that prevents movement while maintaining installation simplicity, it addresses the reliability issue of dangling connectors without compromising ease of installation across various applications.

Implementation Method 1
The invention may also include a pair of flexible springs which engage the supporting surface to provide tension and resistance when the mounting stud is inserted into the supporting surface
Implementation Method 2
The branches flex to pass through an aperture in the supporting surface, then spring back to engage the backside of the supporting surface to retain the rectangular fir tree mount in the rectangular aperture
