Multi-layer Gaming Object with Air-impermeable Bladder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gaming objects, such as soccer and rugby balls, face issues with durability, air retention, and uniform cushioning, especially on rough surfaces, due to materials like PVC and PU, which decompose with weather changes and require time-consuming stitching processes, limiting their performance and shelf life.
Innovation Solution
A multi-layer gaming object with an air impermeable inflatable bladder wrapped in a reinforcing fabric layer and covered with a layered casing, featuring a rubber blended foaming sheet and polyester fabric, providing enhanced strength, resilience, and air retention, while eliminating the need for stitching through a stich-less manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional materials like PVC or PU are used for the outer casing, then the gaming object can be manufactured with basic durability, but the durability and shelf life deteriorate on rough grounds and with weather changes
Solution Approach 1:
The patent uses a composite material structure with an inner bladder made of air-impermeable material (such as rubber or synthetic rubber) and an outer casing made of durable material (such as leather or synthetic leather). This composite structure combines the air-retention properties of the inner bladder with the durability and weather resistance of the outer casing, resolving the contradiction between basic durability and long shelf life under various conditions.
2Strength
If leather panels are used with intermediate windings, then the gaming object achieves basic cushioning, but the cushion effect becomes non-uniform
Solution Approach 1:
The patent applies local quality by ensuring that the intermediate windings are uniformly distributed and wrapped around the bladder in a consistent manner. The windings are applied with uniform tension and spacing, creating consistent cushioning properties across different regions of the gaming object. This uniform application of the intermediate layer ensures that the cushioning effect is homogeneous throughout, resolving the non-uniformity issue.
3Strength
If stitching processes are used to attach the outer casing, then the gaming object achieves structural integrity, but the manufacturing time and complexity increase
Solution Approach 1:
The patent extracts the stitching process from the manufacturing method by using alternative attachment methods such as adhesive bonding or thermal welding to join the outer casing to the intermediate windings and bladder. This elimination of the stitching step removes the need for skilled labor and significantly reduces manufacturing time while maintaining structural integrity through the bonded joints, thereby resolving the contradiction between structural integrity and manufacturing efficiency.
4Strength
If the outer casing is stretched tightly over the pressurized bladder, then high resiliency and rebound are achieved, but air permeability increases
Solution Approach 1:
The patent employs a composite material system where the inner bladder is made of highly elastic, air-impermeable material that maintains air retention even when stretched. The outer casing is made of a different material that provides the necessary tension for resiliency. The intermediate windings layer acts as a barrier that prevents air leakage while allowing the outer casing to be stretched tightly. This multi-material composite structure resolves the contradiction between achieving high resiliency through tight stretching and maintaining air retention.
