Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cutting blade is made rigid and thick to improve cutting efficiency and durability, then the blade deforms under load causing irregular wear and metal residues in processed meat
Solution Approach 1:
The patent applies the dynamics principle by making the cutting blade adjustable in rigidity. The blade can be modified from a rigid state to a more flexible state through mechanical adjustments (such as heating elements or mechanical tensioners) allowing it to adapt its stiffness based on operating conditions. This resolves the contradiction by enabling the blade to be rigid when needed for cutting efficiency but flexible enough to prevent deformation and wear under load.
Solution Approach 2:
The patent employs parameter changes by altering the physical state or mechanical properties of the blade material. Through controlled heating, mechanical adjustment, or phase changes, the blade's rigidity parameter can be dynamically modified during operation. This allows optimization of both cutting performance and wear resistance by adjusting the rigidity parameter according to specific operational requirements.
2Stability of the object's composition
If the cutting blade is made rigid and thick to maintain stability during meat processing, then significant thermal stress and pressure stress are applied to the processed meat
Solution Approach 1:
The patent applies dynamics by making the blade's mechanical properties adjustable rather than fixed. The blade can transition between rigid and flexible states, allowing it to maintain stability during cutting while reducing excessive stress transmission to the meat. This dynamic adjustment capability resolves the contradiction between stability and harmful stress effects.
Solution Approach 2:
The patent changes the rigidity parameter of the blade to optimize the balance between stability and stress reduction. By controlling parameters such as temperature, mechanical tension, or material phase, the blade can achieve the appropriate stiffness level that provides stability during cutting while minimizing thermal and pressure stress on the processed meat.
3Productivity
If the cutting blade operates with high rigidity to ensure cutting efficiency, then the blade experiences significant wear and metal fragments contaminate the processed meat
Solution Approach 1:
The patent applies the dynamics principle by enabling the blade to adjust its rigidity during operation. The blade can operate in a rigid state for efficient cutting when needed, but transition to a more flexible state to reduce wear under continuous operation. This dynamic adaptation resolves the contradiction between cutting efficiency and blade material loss.
Solution Approach 2:
The patent employs parameter changes to control the blade's mechanical properties during operation. By adjusting parameters such as temperature, mechanical stress, or material phase, the blade's rigidity can be optimized to balance cutting efficiency with wear resistance, thereby reducing metal fragment contamination in processed meat while maintaining productivity.
