Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If load receiving platforms are arranged at equal pitch on an endless rotating body, then the structure is simple and stable, but the transportation efficiency decreases because articles cannot be loaded simultaneously into multiple platforms
Solution Approach 1:
The system divides the transportation function into multiple independent transportation units, each with its own load receiving platform that can be controlled separately. This segmentation allows different platforms to operate at different positions and speeds, enabling simultaneous loading into multiple platforms while maintaining overall system simplicity through modular design
Solution Approach 2:
The invention transitions from a static equal-pitch platform arrangement to a dynamic system where platforms can adjust their positions and spacing. The controller enables variable pitch between platforms, allowing them to move to optimal loading positions dynamically. This dynamic adjustment capability resolves the contradiction by maintaining structural simplicity while achieving high transportation efficiency through flexible platform positioning
2Quantity of substance
If multiple load receiving platforms are positioned closely to increase capacity, then transportation capacity increases, but mechanical interference occurs between adjacent platforms
Solution Approach 1:
The system uses dynamic position control to adjust the spacing between platforms based on operational requirements. When high capacity is needed, platforms can be positioned closely; when mechanical interference risk exists, the controller adjusts platform positions to maintain safe spacing. This dynamic adjustment allows the system to achieve high transportation capacity while preventing mechanical interference through real-time position management
3Productivity
If a linear motor system is used to drive platforms independently, then control flexibility and transportation efficiency improve, but the device complexity and cost increase
Solution Approach 1:
The invention replaces traditional mechanical drive systems with electromagnetic linear motors. This substitution eliminates the need for complex mechanical transmissions, gears, and linkages while providing direct electromagnetic propulsion. The linear motors enable independent control of each platform with high precision, achieving superior transportation efficiency while reducing mechanical complexity through the use of electromagnetic fields instead of mechanical components
Solution Approach 2:
The linear motor system serves multiple functions simultaneously: it provides propulsion, position control, and speed regulation for each platform. This multi-functionality reduces the need for separate mechanical systems for each function, thereby reducing overall device complexity while maintaining high transportation efficiency through integrated electromagnetic control

AI summary
A lifting and lowering transportation device is capable of transporting articles between different delivery positions using transportation units, each including a lifting and lowering platform, a linear motor, and a chain. The lifting and lowering platform can pass through the delivery positions by moving along the circumferential track that is common to the transportation units. The linear motor generates the driving force to move the lifting and lowering platform along the circumferential track. The chain is loop-shaped and can circulate along the circulation track corresponding to the circumference path, and the linear motor moves the lifting and lowering platform by circulating the chain by the driving force generated by the linear motor. The circulation of the chain in each transportation unit is controlled independently of the other transportation units.
