Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the ball is made of plastic to meet game requirements, then the ball can be manufactured with holes and smooth surface, but the ball becomes prone to cracking and breaking due to repeated impacts
Solution Approach 1:
The patent applies composite materials by integrating a plastic shell with a internal structural support system. The shell maintains the required smooth surface and hole configurations for gameplay, while the internal support structure (comprising struts and hubs) provides reinforcement to resist cracking and breaking from repeated impacts.
2Adaptability or versatility
If the ball is used outdoors in cold temperatures, then the ball can be played in various environments, but the plastic becomes brittle and shatters upon high-speed impact
Solution Approach 1:
The patent uses composite materials to combine the plastic shell (which maintains outdoor adaptability) with an internal support structure made of materials that provide impact resistance even at low temperatures. This composite approach allows the ball to maintain its plastic characteristics while gaining enhanced durability in cold conditions.
Solution Approach 2:
The internal support structure acts as a pre-positioned reinforcement that cushions against impact forces before they can cause the plastic shell to shatter. This beforehand cushioning effect protects the brittle plastic from high-speed impacts during outdoor play in cold temperatures.
3Duration of action of stationary object
If the ball is used for extended periods, then the ball can provide long-term value, but the plastic ages and becomes increasingly vulnerable to environmental stress factors
Solution Approach 1:
The patent employs composite materials where the internal support structure compensates for the aging of the plastic shell. As the plastic ages and becomes more vulnerable to environmental stress, the reinforcement structure maintains the ball's integrity and extends its functional life.
Solution Approach 2:
The internal support structure provides ongoing protection against environmental stress factors throughout the ball's service life. This beforehand cushioning effect counteracts the increasing vulnerability of aged plastic, maintaining reliability over extended periods.
4Productivity
If the ball is discarded after cracking, then the ball can be replaced, but this creates plastic waste and environmental harm
Solution Approach 1:
The patent uses composite materials to create a ball with enhanced durability that can withstand repeated impacts without cracking. This extends the ball's functional life, reducing the frequency of replacement and consequently reducing plastic waste.
Solution Approach 2:
The patent reverses the disposable approach by creating a durable, long-lasting ball that eliminates the need for frequent replacement. Instead of discarding the ball after cracking, the reinforced design allows it to continue serving its purpose for extended periods, reducing waste.

AI summary
Through the use of an internal support system integrated with the interior shell of a hollow ball, the concentration of impact stress to the ball's shell during game play is reduced through better dispersion and resistance of applied force, while also reinforcing the ball's shell at its weakest points, which are the holes, thus making it more resilient and thereby less susceptible to breakage. Enhanced fortification against impact stress applied during gameplay serves to increase the usable life of the ball.
