Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If closed loop conveyors with cam guides and sliding guides are used to push and transfer products, then the products can be transferred into cartons or boxes, but the structure becomes complex and requires numerous mechanical components that need adjustment for size changes
Solution Approach 1:
The patent replaces the complex mechanical system of closed loop conveyors, cam guides, and sliding guides with a linear driving unit that uses a stator and permanent magnets to directly move the pusher element along a linear path. This substitution eliminates numerous mechanical components and their associated adjustments, achieving both simplified structure and adaptability to size changes through direct electromagnetic actuation.
Solution Approach 2:
The invention extracts and removes the unnecessary intermediate mechanical components (cam guides, sliding guides, closed loop conveyor structure) from the traditional pushing apparatus. By taking out these complex elements and retaining only the essential linear motion function through a simplified direct-drive mechanism, the patent achieves structural simplification while maintaining adaptability.
2Productivity
If closed loop conveyors with multiple mechanical components are used, then product transfer can be achieved, but the transfer velocity cannot reach high speeds due to mechanical complexity
Solution Approach 1:
The patent replaces the mechanical transmission system with a direct electromagnetic driving system using a linear motor with stator and permanent magnets. This substitution eliminates mechanical friction, inertia, and component limitations that restrict speed, enabling high-velocity product transfer while reducing overall system complexity.
3Ease of manufacture
If numerous mechanical components are used in the pushing apparatus, then the pushing function can be achieved, but the structure requires adjustment and maintenance for size changes
Solution Approach 1:
The invention removes the numerous mechanical components that require adjustment and maintenance. By extracting these unnecessary elements and using a simplified linear driving unit with electromagnetic actuation, the patent achieves ease of manufacture and adjustment while minimizing the total number of components.
Solution Approach 2:
The linear driving unit with stator and permanent magnets serves multiple functions simultaneously: it provides the pushing force, controls the motion along the linear path, and can be easily repositioned or reconfigured for different product sizes. This multi-functionality eliminates the need for separate adjustment mechanisms for each component.
