Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fixing and positioning ton bags during recycling processes face challenges due to their weight and compact space, leading to difficulty in locating and fixing the bags, which can result in damage and inefficiency.
Innovation Solution
A fixing assembly comprising a connecting sleeve, a spike piece, and an elastic piece that spirally winds around the spike piece, allowing for elastic deformation to form a convex structure that securely fixes the ton bag, and can quickly switch between fixed and unfixed positions by rotating the spike piece relative to the connecting sleeve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ton bag is simply fixed at four corners or edges, then the fixing operation is simple, but the positioning accuracy is poor and the ton bag is difficult to locate
Solution Approach 1:
The fixing assembly is divided into multiple functional components: a connecting sleeve for mounting, a spike piece for penetration and rotation, and an elastic piece for providing elastic pressing force. This segmentation allows each component to perform its specific function efficiently, resolving the contradiction between simple operation and accurate positioning.
Solution Approach 2:
The spike piece is designed to be rotatable relative to the connecting sleeve, transforming the fixing mechanism from a static simple pin to a dynamic system. By rotating the spike piece, the elastic piece deforms to form a spiral convex structure that provides both easy operation and precise positioning, achieving both requirements simultaneously.
2Reliability
If the ton bag is firmly fixed to prevent falling, then the reliability of fixing is improved, but the device complexity increases due to compact space and heavy weight
Solution Approach 1:
The elastic piece automatically generates elastic deformation when the spike piece rotates, forming the spiral convex structure without requiring additional actuators or complex mechanisms. This self-service mechanism provides reliable fixing while keeping the device structure simple, resolving the contradiction between reliability and device complexity.
3Reliability
If the spike piece rotates in the direction opposite to spiral winding, then the elastic pressing effect is enhanced for better fixing, but the elastic piece undergoes greater deformation
Solution Approach 1:
The elastic piece is designed with specific material parameters and geometric parameters that allow it to undergo controlled elastic deformation. By optimizing these parameters, the elastic piece can withstand the deformation required to form the spiral convex structure while maintaining sufficient strength, resolving the contradiction between pressing effect and piece strength.
