Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sports training walls for racquet sports like tennis are often temporary, costly, and deteriorate quickly, failing to provide a durable and realistic training experience.
Innovation Solution
A free-standing sports training wall featuring a heat-strengthened glass panel attached to a frame, providing a smooth, transparent, and durable rebound surface with markings to simulate a tennis net, which is resistant to damage and maintains its effectiveness over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockwork walls, mesh walls, or metal sheet walls are used to form a planar rebound surface, then the training wall can be constructed, but the rebound surface deteriorates over time with reducing strength and smoothness
Solution Approach 1:
The patent applies heat-strengthening treatment to the glass panel, fundamentally changing its physical properties. This thermal treatment increases the glass's strength, hardness, and resistance to impact and weathering, directly resolving the durability and service life issues of conventional rebound surfaces.
Solution Approach 2:
The patent uses a glass panel as a composite material solution, combining the transparency and smoothness of glass with the strength enhancement from heat-strengthening. This creates a rebound surface that maintains its properties over time without the deterioration seen in blockwork, mesh, or metal sheet alternatives.
2Reliability
If a heat-strengthened glass panel is used for the rebound surface, then durability and smoothness are improved, but the cost and complexity of manufacture increase
Solution Approach 1:
The heat-strengthening process, while adding a manufacturing step, is a well-established industrial process that transforms ordinary glass into a durable material. The parameter change in thermal treatment creates a product with significantly improved reliability, justifying the additional manufacturing complexity.
3Illumination intensity
If a transparent rebound surface is used, then visual realism is improved, but the strength and impact resistance may be reduced
Solution Approach 1:
The heat-strengthening process fundamentally changes the physical parameters of the glass, increasing its strength and impact resistance by a factor of 3-5 times compared to ordinary glass. This allows the glass to maintain transparency while withstanding tennis ball impacts and environmental stresses.
Solution Approach 2:
The patent creates a composite solution by combining transparent glass with heat-strengthening treatment, achieving a material that possesses both optical transparency and mechanical strength suitable for sports training applications.
