Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If 16Mn steel is used for liner plate, then impact resistance is improved, but wear resistance deteriorates
Solution Approach 1:
The patent applies composite materials by combining 16Mn steel base material with hardfacing coatings (such as nickel-hard alloy, chromium carbide, or ceramic coatings). This composite structure allows the liner plate to simultaneously achieve the impact resistance of 16Mn steel and the wear resistance of the hardfacing coating layer, resolving the contradiction between these two properties.
2Reliability
If liner plate is frequently maintained or replaced, then wear resistance is improved, but productivity deteriorates
Solution Approach 1:
The patent applies preliminary action by performing hardfacing coating treatment on the liner plate before it is installed in the hoisting container. This pre-applied protective layer provides enhanced wear resistance from the outset, extending the service life of the liner plate and reducing the frequency of maintenance and replacement operations, thereby maintaining continuous productivity.
Solution Approach 2:
The patent applies parameter changes by modifying the surface properties of the liner plate through hardfacing coating, which changes the surface hardness, wear resistance, and friction characteristics. This parameter modification allows the liner plate to withstand prolonged exposure to abrasive materials without requiring frequent replacement, thus maintaining high productivity.
3Measurement precision
If detection device is added, then measurement precision is improved, but device complexity deteriorates
Solution Approach 1:
The patent applies the taking out principle by extracting and isolating the detection function into separate, modular sensor units (impact sensors, wear sensors, and friction sensors) that can be independently installed on the liner plate. This modular approach enables precise measurement of impact, wear, and friction parameters without requiring a complex integrated detection system, thus improving measurement precision while minimizing device complexity.

Function Achieved in This Case
The device effectively simulates actual impact and friction conditions, enabling real-time measurement of forces and wear rates, thus providing a theoretical basis for extending the service life of the liner plates and reducing maintenance needs.
Implementation Method 1
one side of the impact force sensor (42) is fixed onto the liner plate backboard (12), and the other side thereof is in contact with a left plate surface of a hoisting container (11)
Implementation Method 2
The tension-compression sensor (21) is used for measuring a friction force borne by the liner plate (41) when a material falls down to impact on the liner plate
Implementation Method 3
