Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydraulics, pneumatics, and electronics are used for controlled netting output, then netting output control is achieved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex hydraulic, pneumatic, and electronic systems with a simple mechanical inhibiting element. This element uses basic mechanical principles (friction, normal force) to control netting output, eliminating the need for sophisticated control systems while maintaining operational effectiveness.
Solution Approach 2:
The inhibiting element is designed as a simple, inexpensive mechanical component that can be easily replaced if needed. Its straightforward design reduces both initial cost and maintenance requirements compared to expensive electronic or hydraulic systems.
2Ease of operation
If hydraulics, pneumatics, and electronics are used for controlled netting output, then netting output control is achieved, but cost increases
Solution Approach 1:
The patent substitutes expensive hydraulic, pneumatic, and electronic components with a simple mechanical inhibiting element. This dramatically reduces manufacturing costs while preserving the essential function of controlled netting output.
Solution Approach 2:
The inhibiting element is designed as a low-cost mechanical component that achieves the control function without requiring expensive materials or complex manufacturing processes.
3Device complexity
If uncontrolled netting output is prevented by mechanical means, then purely mechanical handling is achieved, but netting output control mechanism must be designed
Solution Approach 1:
The patent uses a simple mechanical inhibiting element that leverages basic physical principles (friction, normal force) to control netting output. This approach requires minimal design complexity while achieving reliable mechanical handling.
Solution Approach 2:
The inhibiting element automatically controls netting output through its mechanical design without requiring external control systems. The element's position and physical properties self-regulate the netting flow based on gravitational and frictional forces.
