Solution Overview
Problem
Existing windproof nets for material piles and traffic lines are fixed structures, making them unsuitable for outdoor snow sports competition fields where they need to be folded and unfolded, and they are not adaptable for large-span applications.
Innovation Solution
A foldable windproof unit with a flexible net supported by a load-bearing rope and driven by a traction rope through a winding mechanism, allowing for easy unfolding and folding, and a large-span windproof net structure composed of these units with towers and pulley assemblies for stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed steel supports and rigid/flexible windproof nets are used, then windproof effectiveness is improved, but the structure cannot be folded and steel consumption increases
Solution Approach 1:
The patent replaces rigid steel supports with flexible load-bearing ropes that can be easily deployed and folded. The windproof net itself is made flexible to work in conjunction with the rope support system, enabling the entire structure to be collapsible while maintaining windproof functionality during use.
Solution Approach 2:
The patent extracts the supporting function from rigid steel supports and transfers it to flexible load-bearing ropes. This extraction allows the removal of excessive steel materials while maintaining structural integrity and windproof effectiveness through the rope-net system.
2Stability of the object's composition
If fixed steel supports are used, then structural stability is improved, but device complexity and cost increase
Solution Approach 1:
The patent substitutes the traditional mechanical steel support system with a rope-based tension system. This replacement simplifies the overall structure by eliminating complex steel frameworks while maintaining stability through the tensioned rope-net configuration.
3Adaptability or versatility
If manual insertion of connecting rods is used, then foldability is achieved, but operation complexity increases for large fields
Solution Approach 1:
The patent employs floating piles that automatically penetrate and stabilize in the ground without manual intervention. The windproof net structure self-deploys and self-stabilizes through the floating pile mechanism, eliminating the need for manual connecting rod insertion and making the system easy to operate even in large fields.
4Adaptability or versatility
If movable stand columns are used to drive unfolding, then adaptability is improved, but stability of movable components becomes a concern
Solution Approach 1:
The patent uses floating piles that dynamically adapt to ground conditions while providing stable support. The floating nature allows the piles to self-adjust and firm up in the ground, providing reliable stability without requiring complex movable stand column mechanisms.
