Resilient Edge for Drainage Channel Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drainage channels for athletic fields often have hard edges that can injure athletes upon impact, as they lack a soft and deformable material to absorb external forces effectively.
Innovation Solution
The integration of a resilient edge with an elongated body made of elastically deformable material, such as polyvinylchloride or vinyl rubber, into the drainage channel, which features a hollowed portion and an attachment structure to secure it to the channel, providing a softer contact area and reduced resistance to external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hard material is used for the drainage channel body, then the structural strength and durability are improved, but the safety of athletes is worsened due to potential injury from hard edges
Solution Approach 1:
The drainage channel incorporates a resilient edge portion made of elastomeric material at the location where athletes may contact it, while the main body of the channel remains made of hard material for structural strength. This local quality change allows the channel to maintain overall strength while providing a safe, deformable contact surface at the critical edge location.
Solution Approach 2:
The drainage channel uses a composite construction combining a hard material body (such as concrete or rigid plastic) with an elastomeric resilient edge material. This composite approach allows the channel to simultaneously achieve the structural integrity of hard materials and the safety characteristics of soft, deformable materials at the contact surface.
2Object-affected harmful factors
If a resilient edge is added to the drainage channel, then the safety and comfort for athletes are improved, but the device complexity increases
Solution Approach 1:
The resilient edge portion is merged with the drainage channel body to form an integrated structure. The resilient edge can be attached to or formed as part of the channel body, combining the safety function with the existing channel structure rather than adding a completely separate component.
Solution Approach 2:
The resilient edge is implemented as a flexible elastomeric portion that can be molded or attached to the channel body. This flexible shell approach provides the safety function through a relatively simple geometric form rather than a complex mechanical structure.
3Object-affected harmful factors
If the resilient edge is made highly deformable, then the impact absorption capability is improved, but the structural stability is worsened
Solution Approach 1:
The elastomeric resilient material is applied specifically at the edge portion where impact occurs, while the main body of the channel maintains its rigid structure. This localized application of deformability allows the edge to absorb impact forces without compromising the overall structural stability of the drainage channel.
Solution Approach 2:
The drainage channel is segmented into distinct functional zones: a rigid main body for structural stability and a separately defined resilient edge portion for impact absorption. This segmentation allows each portion to be optimized for its specific function while maintaining overall system stability.

Function Achieved in This Case
The resilient edge effectively absorbs impact forces, reducing the risk of injury to athletes by providing a flexible and deformable surface that can deflect inwardly, while remaining securely attached to the drainage channel.
Implementation Method 1
an elongated body formed of an elastically deformable material; a wall of the resilient edge is capable of deforming inwardly towards the opening
