Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor systems lack effective support structures in the loading zone that can absorb and manage the impact of materials being loaded, leading to potential damage and inefficiencies.
Innovation Solution
An impact cradle with a frame and pad assembly, featuring removable resilient pads supported by retainer clips and arcuate supports, designed to partially support the conveyor belt and absorb the impact of materials being loaded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conveyor systems use simple support structures in the loading zone, then the device complexity is low, but the impact of materials causes damage to the conveyor belt and reduces reliability
Solution Approach 1:
The patent applies beforehand cushioning by installing resilient pads on the impact cradle before materials are loaded. These pads are specifically positioned to cushion the impact of materials before they contact the conveyor belt, preventing damage in advance. The pads absorb impact forces through their resilient properties, protecting the conveyor belt from repeated striking during normal operation.
Solution Approach 2:
The impact cradle with resilient pads serves as an intermediary element between the dropped materials and the conveyor belt. Instead of materials directly impacting the belt, they first contact the pads on the cradle, which then transfer the load more gradually to the belt. This intermediary structure distributes and softens the impact forces, reducing damage while maintaining structural integrity.
2Productivity
If conventional conveyor systems lack impact absorption structures, then the device complexity is low, but the operational efficiency decreases due to material damage and belt wear
Solution Approach 1:
The impact cradle structure is segmented into distinct functional components: the cradle frame, multiple resilient pads positioned at different locations, and mounting mechanisms. This segmentation allows each component to be optimized for its specific function - the frame provides structural support while individual pads handle impact absorption. The segmented design also enables easier maintenance and replacement of worn pads without replacing the entire structure.
3Strength
If conventional conveyor systems use rigid support structures in the loading zone, then the structural strength is high, but the impact forces are not absorbed, causing damage to the conveyor belt
Solution Approach 1:
The patent applies parameter changes by transitioning from rigid support structures to resilient pads with specific material properties. The pads are made from elastomeric or polymeric materials with controlled durometer values (hardness), thickness, and density parameters. These parameter changes allow the structure to maintain sufficient strength for support while simultaneously providing impact absorption through material elasticity and energy dissipation characteristics.
