Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing static mechanical repelling devices for winged animals on surfaces like gutters and cornices are unstable due to mismatched angles between repelling elements, allowing animals to potentially move or cross the barrier.
Innovation Solution
The repelling device features a support base with reliefs in its slots to stabilize the first repelling element by increasing its contact height, ensuring equal angles between all repelling elements and providing a dense barrier with modular design for adaptability and secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base sections of repelling elements are arranged mutually transversally and overlapping in the housing seat, then the barrier effect is improved, but the distance between base sections becomes unequal causing instability
Solution Approach 1:
The patent applies local quality by providing different distance relationships between base sections: the first base section is at a first distance from the upper surface while the second base section is at a second distance greater than the first. This localized differentiation in positioning resolves the instability caused by equal distances while maintaining the overlapping transversal arrangement for barrier effectiveness.
Solution Approach 2:
The patent changes the parameter of distance between base sections and the upper surface of the support base. By setting the first distance less than the second distance, the patent optimizes the positioning parameters of repelling elements to achieve both stable fixation and effective barrier function, resolving the contradiction between reliability and stability.
2Ease of manufacture
If repelling elements are fixed with unequal distances from base sections to upper surface, then fixation is achieved, but angular mismatch occurs causing oscillation
Solution Approach 1:
The patent applies local quality by creating different spatial relationships for different repelling elements. The first repelling element has its base section at a first distance from the upper surface, while the second repelling element has its base section at a second distance greater than the first. This localized differentiation ensures equal tip angles and prevents oscillation while maintaining ease of fixation through the housing seat design.
Solution Approach 2:
The patent optimizes the positioning parameters by setting specific distance relationships between base sections and the upper surface. By controlling these distance parameters differently for different repelling elements, the patent achieves both secure fixation and angular consistency, eliminating the oscillation problem.
3Ease of operation
If through slots are used to fix repelling elements, then removable association is achieved, but insufficient contact height causes instability
Solution Approach 1:
The patent extends the through slots in the vertical dimension by adding reliefs that protrude from the lower surface toward the upper surface. This dimensional extension increases the contact height between the slots and the base sections of repelling elements, providing enhanced stability while maintaining the removable association feature through the same slot structure.
Solution Approach 2:
The patent creates a composite structural feature by combining the through slot with the relief structure. The relief acts as an extension of the slot, creating a composite fixation structure that provides both removable association and increased contact height for stability, resolving the contradiction between ease of operation and stability.
