Engineering Contradiction Analysis
1Object-generated harmful factors
If only naturally derived components are used to produce a buffer material, then environmental load is reduced, but significant deformation such as buckling easily occurs due to relatively small external force
Solution Approach 1:
The patent combines multiple naturally derived binding materials (starch, natural wax, and protein-based binder) to create a composite binding system that achieves both environmental sustainability and mechanical strength. This merging of different natural binders resolves the contradiction by providing enhanced buckling resistance while maintaining natural composition.
Solution Approach 2:
The invention uses a composite material approach by formulating a binding material that contains multiple components (starch 5-30 parts, natural wax 2-15 parts, protein-based binder 5-20 parts per 100 parts cellulose fibers). This composite natural binder system provides the mechanical strength needed to prevent buckling while remaining environmentally friendly.
2Strength
If thermoplastic resin is used to bind used paper pulp fibers, then binding strength is improved, but reduction in environmental load is insufficient and recyclability is difficult
Solution Approach 1:
The patent changes the chemical composition parameters by replacing synthetic thermoplastic resins with naturally derived binding materials. The specific formulation (starch 5-30 parts, natural wax 2-15 parts, protein-based binder 5-20 parts per 100 parts cellulose fibers) provides sufficient binding strength while maintaining natural composition for reduced environmental load and improved recyclability.
Solution Approach 2:
The invention enables easy recycling by using naturally derived binding materials that can be broken down and recovered. The cellulose fiber-based composition with natural binders allows the buffer material to be discarded and recovered more sustainably compared to thermoplastic resin-bound materials.
3Strength
If binding material content is increased to improve strength, then buckling resistance is improved, but water repellency and durability in humid environment deteriorate
Solution Approach 1:
The patent applies local quality by assigning different functional roles to different binding material components. Starch provides binding and strength, natural wax provides water repellency and durability, and protein-based binder enhances overall cohesion. This functional differentiation allows the binding material system to achieve both buckling resistance and water resistance simultaneously.
Solution Approach 2:
The composite binding material system with specific component ratios (starch 5-30 parts, natural wax 2-15 parts, protein-based binder 5-20 parts per 100 parts cellulose fibers) creates a synergistic effect where each component contributes its unique properties, achieving both mechanical strength and water resistance.
