Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If quenching is performed to improve material strength and hardness, then material strength and hardness are improved, but uneven cooling causes deformation
Solution Approach 1:
The positioning component is segmented into multiple protrusions that contact different regions of the workpiece. These protrusions divide the workpiece into multiple contact points, ensuring uniform distribution of clamping force and heat dissipation across the entire workpiece surface, thereby preventing deformation during quenching while maintaining material strength.
Solution Approach 2:
The positioning component features protrusions with specific local structures that provide both clamping and heat dissipation functions at contact points. The heat dissipation channels are locally positioned within the protrusions to facilitate targeted cooling at critical areas, ensuring uniform temperature distribution and preventing localized deformation while maintaining overall workpiece strength.
2Shape
If high-temperature leveling operation is performed to improve flatness, then flatness is improved, but material strength and hardness are weakened
Solution Approach 1:
The positioning component with heat dissipation channels performs preliminary cooling action during the quenching process itself. By providing uniform heat dissipation through the protrusions at the critical cooling stage, the workpiece achieves uniform temperature distribution and maintains flatness without requiring subsequent high-temperature leveling operations, thus preserving material strength and hardness.
3Weight of moving object
If metal case is made thinner and lighter to comply with design trends, then weight is reduced, but material strength becomes insufficient
Solution Approach 1:
The quenching fixture enables precise control of cooling parameters through its heat dissipation channels and protrusion structure. By optimizing the cooling rate and temperature distribution during quenching, the metal case achieves maximum hardening and strength enhancement, allowing thinner designs to attain sufficient material strength through controlled phase transformation parameters.

AI summary
A quenching fixture adapted to clamp at least one workpiece is provided. The quenching fixture includes a first positioning component and a second positioning component. Both of the first positioning component and the second positioning component have a positioning surface, multiple protrusions protruding from the positioning surface and a heat dissipation channel disposed between the protrusions in a staggered manner. The positioning surface of the first positioning component faces the positioning surface of the second positioning component, and the protrusions of the first positioning component overlap the protrusions of the second positioning component. The workpiece is clamped between the protrusions of the first positioning component and the protrusions of the second positioning component.
