Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional juicing mechanism is used, then device complexity is low, but juicing efficiency is insufficient due to inadequate pressurization
Solution Approach 1:
The patent replaces the conventional mechanical pressurization system with a piezoelectric-based system. The piezoelectric element converts electrical energy directly into mechanical vibrations and pressure, eliminating the need for complex mechanical linkages and providing more effective pressurization of the juice between the screw housing and driving screw.
Solution Approach 2:
The patent introduces piezoelectric elements that can dynamically adjust pressure parameters through electrical control. By changing the electrical input to the piezoelectric element, the pressurization force can be precisely controlled and optimized for different juicing conditions, thereby improving juicing efficiency without increasing mechanical complexity.
2Productivity
If piezoelectric element is added to improve pressurization, then juicing efficiency improves, but device complexity increases
Solution Approach 1:
The piezoelectric element substitutes for complex mechanical pressurization mechanisms, using electro-mechanical conversion to achieve effective pressurization with simpler overall system architecture.
Solution Approach 2:
The piezoelectric element serves multiple functions: it generates mechanical vibrations for pressurization, creates ultrasonic waves for enhanced juice extraction, and can be controlled electrically for precise pressure regulation. This multi-functionality improves juicing efficiency while adding minimal complexity compared to multiple separate mechanical components.
