Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic materials like rubber and polymer-based particles are used as infill, then proper foot traction and durability are achieved, but environmental pollution increases due to microplastic contamination
Solution Approach 1:
The invention changes the material parameter from synthetic polymer to natural organic material (olive pit fragments). The olive pit fragments are processed through tumbling to achieve proper surface characteristics for foot traction while maintaining the natural organic composition, thus eliminating microplastic pollution concerns.
Solution Approach 2:
The invention uses natural organic material (olive pit fragments) that can biodegrade naturally at the end of its service life, replacing persistent synthetic materials. This aligns with the principle of using materials that can be naturally decomposed and returned to the environment without harmful effects.
2Object-generated harmful factors
If organic materials are used as infill to reduce environmental impact, then biodegradation is reduced, but performance in varying weather conditions deteriorates
Solution Approach 1:
The olive pit fragments undergo preliminary thermal treatment and tumbling processing before being installed as infill. The thermal treatment enhances durability and resistance to weather conditions, while the tumbling process creates proper surface characteristics. This preliminary preparation ensures the organic material performs reliably in varying weather conditions.
Solution Approach 2:
The invention applies thermal treatment to change the physical and chemical parameters of the olive pit fragments, enhancing their durability, hardness, and resistance to biodegradation. This parameter change allows the organic material to maintain performance in varying weather conditions while remaining environmentally friendly.
3Object-generated harmful factors
If olive pit fragments are used as infill to provide environmental benefits, then microplastic pollution is reduced, but microbial infestation in moist conditions increases
Solution Approach 1:
The olive pit fragments undergo preliminary thermal treatment before installation to reduce moisture content and create an environment less favorable for microbial growth. This preliminary action addresses the potential issue of microbial infestation while maintaining the environmental benefits of using natural organic material.
Solution Approach 2:
The thermal treatment process changes the moisture content and physical parameters of the olive pit fragments, making them less susceptible to microbial infestation in moist and wet conditions. This parameter modification allows the organic infill to resist microbial attacks while maintaining its environmental advantages.
4Reliability
If olive pit fragments are tumbled to smooth edges and improve performance, then foot traction is enhanced, but manufacturing complexity increases
Solution Approach 1:
The tumbling process allows the olive pit fragments to self-smooth their edges through mutual abrasion during rotation. This self-service mechanism naturally creates the proper surface characteristics for foot traction without requiring additional machining or processing steps, thus limiting the increase in manufacturing complexity.
