Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removable cover systems for trailers and trailers are not designed to accommodate the deformation of side walls due to loading and unloading, leading to mechanical stresses, plastic deformation, and jamming issues.
Innovation Solution
A removable cover system with partially hollow hoops equipped with sliders and a spring tensioning device, allowing for adjustment to wall deformations through sliding, rotational freedom, and spring tension, preventing jamming and stress accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a removable cover system uses rigid hoops and cables for covering trailers, then the cover can be effectively moved and secured, but the system cannot accommodate wall deformations during loading and unloading, leading to high mechanical stresses and potential jamming
Solution Approach 1:
The patent applies the dynamics principle by making the hoops partially hollow and enabling them to slide along the guide rails. This dynamic configuration allows the hoops to adjust their position and accommodate wall deformations during loading and unloading operations, resolving the contradiction between operational reliability and adaptability to deformation.
Solution Approach 2:
The patent changes the structural parameter of the hoops from completely rigid to partially hollow, and modifies the connection system to include sliding mechanisms. These parameter changes enable the cover system to adapt to varying wall positions while maintaining reliable operation throughout the loading and unloading cycle.
2Strength
If the hoops are made rigid to maintain structural integrity, then the cover system provides stable support, but it cannot accommodate the displacement of upper edges of side walls exceeding 15 cm, causing plastic deformation and slider jamming
Solution Approach 1:
The hoops are designed as partially hollow structures that can slide along guide rails, transforming from a static rigid structure to a dynamic adaptive structure. This allows the hoops to maintain structural strength while accommodating wall displacements up to 15 cm without causing plastic deformation or slider jamming.
Solution Approach 2:
The connection between hoops and the cover system is segmented into multiple movable components including sliders and sliding mechanisms. This segmentation allows each component to move independently to accommodate wall deformations while maintaining overall structural integrity through the coordinated action of these segmented elements.
3Ease of manufacture
If the cover system is designed for rigid parallelepiped trailers, then the initial installation is simple, but it fails to account for deformations occurring during actual loading and unloading operations
Solution Approach 1:
The patent introduces dynamic sliding mechanisms and partially hollow hoops that automatically adjust to wall deformations during loading and unloading. While the initial installation remains relatively simple, the system's dynamic components ensure reliable performance under actual loading conditions by accommodating wall displacements without requiring complex adjustments or interventions.
