Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If resistance welding is used to attach traction elements to the chain link body, then the traction elements can be attached to the chain link body, but the production process becomes complex and energy-consuming, and safety risks arise due to the use of electric current
Solution Approach 1:
The patent replaces resistance welding (electrical process) with friction welding (mechanical process). The friction welding process uses mechanical friction between the traction element and chain link body to generate heat and create the weld, eliminating the need for electric current and complex electrical equipment, thereby simplifying the production process and reducing energy consumption.
Solution Approach 2:
The patent changes the welding parameters from electrical (resistance welding) to mechanical (friction welding). By changing the fundamental parameter of the welding process from electrical resistance to mechanical friction, the patent achieves a simpler, safer, and more energy-efficient production process while maintaining the attachment functionality.
2Reliability
If resistance welding is used to attach traction elements to the chain link body, then the traction elements can be attached to the chain link body, but safety risks arise due to the use of electric current
Solution Approach 1:
The patent replaces resistance welding (electrical process) with friction welding (mechanical process). The friction welding process uses mechanical friction between the traction element and chain link body to generate heat and create the weld, eliminating the need for electric current and complex electrical equipment, thereby simplifying the production process and reducing energy consumption.
3Adaptability or versatility
If traditional welding methods are used to attach traction elements, then the attachment can be made, but the heat input is not locally limited and the process is less flexible
Solution Approach 1:
The patent applies local quality by concentrating the heat generation and welding action at the precise contact point between the traction element and chain link body. The friction welding process generates heat only where the two surfaces are in contact and rubbing against each other, allowing localized welding without affecting surrounding areas, thus enabling flexible attachment at diverse points on the chain link body.
