Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional abrasive binders are used, then manufacturing cost is minimized, but binding strength and toughness are insufficient
Solution Approach 1:
The patent modifies the chemical composition parameters of the binder by incorporating polythiol crosslinking agents and specific curing agents into the resin system. This changes the molecular structure and crosslinking density of the binder, thereby improving binding strength and toughness while maintaining manufacturing feasibility through standard curing processes.
Solution Approach 2:
The patent creates a composite binder system by combining multiple components including polythiol crosslinking agents, curing agents, and resin matrices. This composite approach synergistically improves binding strength and toughness beyond what single-component binders can achieve, while the components remain manufacturable using conventional processes.
2Reliability
If conventional abrasive binders are used, then flexibility is adequate, but random scratch formation increases
Solution Approach 1:
The patent adjusts the crosslinking density and molecular structure parameters of the binder through polythiol crosslinking. This creates a more stable and uniform binder composition that firmly holds abrasive particles, preventing their movement and the subsequent formation of random scratches on the workpiece surface.
3Duration of action of moving object
If binder toughness is improved, then abrading lifetime increases, but manufacturing complexity increases
Solution Approach 1:
The patent introduces polythiol crosslinking agents as intermediary substances that facilitate the formation of a tough, durable binder matrix. These crosslinking agents act as mediators between the resin components and the curing agents, creating a robust network structure that extends abrading lifetime while keeping the formulation process manageable through standard curing procedures.
