Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermoplastic-based floorcovering products are used, then cost and wear resistance are improved, but biodegradability deteriorates
Solution Approach 1:
The patent creates a composite material system combining thermoplastic polymers (for wear resistance) with biodegradation-inducing additives (for biodegradability). This allows the flooring product to maintain the mechanical properties of thermoplastics while gaining the ability to biodegrade under anaerobic conditions, resolving the contradiction between durability and environmental compatibility.
Solution Approach 2:
The patent modifies the chemical parameters of thermoplastic materials by incorporating specific biodegradation-inducing additives that change the material's degradation characteristics. This allows the material to maintain stable properties during use but undergo controlled biodegradation under anaerobic conditions, balancing wear resistance with environmental biodegradability.
2Object-affected harmful factors
If inherently biodegradable polymers are used, then biodegradability is improved, but cost and wear properties deteriorate
Solution Approach 1:
Instead of using purely biodegradable polymers, the patent creates a composite where thermoplastic polymers (providing wear resistance) are combined with biodegradation-inducing additives. This hybrid approach maintains the superior mechanical and wear properties of thermoplastics while enabling biodegradability through the additive components.
Solution Approach 2:
The biodegradation-inducing additives act as intermediaries that bridge the gap between thermoplastic materials and biodegradability. These additives facilitate the biodegradation process under anaerobic conditions without compromising the base thermoplastic material's wear-resistant properties during normal use.
3Object-affected harmful factors
If biodegradable additives are incorporated, then biodegradability is improved, but product stability during use deteriorates
Solution Approach 1:
The biodegradation-inducing additives are incorporated at specific concentrations and locations within the thermoplastic matrix, creating local zones that remain stable during normal use but become active under anaerobic degradation conditions. This localized approach maintains overall product stability while enabling controlled biodegradability when needed.
Solution Approach 2:
The patent utilizes parameter changes in the additive's activity based on environmental conditions. The biodegradation-inducing additives remain inactive or stable during normal use conditions but become activated under anaerobic conditions, enabling controlled biodegradation only when the product is discarded and exposed to appropriate environmental conditions.
4Ease of manufacture
If thermoplastic materials are used, then manufacturing ease and cost are improved, but environmental impact deteriorates
Solution Approach 1:
The patent maintains the ease of manufacturing thermoplastic materials while adding biodegradation capability through incorporated additives. The composite formulation allows existing thermoplastic manufacturing processes to be used with minimal modification, maintaining manufacturing ease while eliminating long-term landfill waste through controlled biodegradation.

AI summary
Single-layered and multi-layered polymer-based flooring products are provided, which are formulated and constructed in such a manner as to render the products susceptible to biodegradation under controlled anaerobic conditions. More particularly, the polymer-based flooring products may contain a biodegradable additive that enhances the susceptibility of the thermoplastic polymer in the flooring product to anaerobic biodegradation. Thus, the resulting flooring products are environmentally-friendly and can naturally degrade in landfill conditions over time.
