Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional cross belt sorting trolley structure is adopted, then the conveying function is achieved, but the overall structure becomes complex and heavy
Solution Approach 1:
The trolley is divided into modular components including an upper conveying unit with belt supporting plate and side plates, and a lower frame with walking wheel assemblies. This segmentation allows each component to be optimized independently, reducing overall complexity and weight while maintaining conveying functionality.
Solution Approach 2:
The side plates are integrated with both the belt supporting plate and the lower frame through vertical connecting plates, merging multiple structural functions into unified components. This reduces the number of separate parts and simplifies the overall structure while maintaining strength.
2Strength
If multiple components are used to achieve conveying function, then the structural strength is improved, but the number of components increases and manufacturing cost rises
Solution Approach 1:
The side plates serve multiple functions: supporting the belt, connecting to the lower frame, and providing mounting surfaces for rollers. This multi-functionality reduces the number of components needed while maintaining structural strength through integrated design.
Solution Approach 2:
The vertical connecting plates are pre-designed with mounting holes and connection features that enable straightforward assembly. This preliminary design of connection interfaces simplifies the assembly process and reduces the number of additional components needed for assembly.
3Manufacturing precision
If traditional connection methods are used between components, then the assembly is achieved, but the installation and debugging accuracy is low due to machining precision limitations
Solution Approach 1:
The vertical connecting plates act as intermediary components between the upper conveying unit and lower frame, providing precise alignment features and mounting holes that ensure accurate installation. This intermediary structure compensates for machining precision limitations in the main components.
Solution Approach 2:
The connection interfaces are designed with standardized mounting holes and alignment features that ensure consistent positioning regardless of minor variations in component manufacturing. This equipotential design ensures that assembly accuracy is maintained across different production batches.
4Stability of the object's composition
If complicated connection structures are used, then the structural stability is improved, but the running stability is affected and working noise increases
Solution Approach 1:
The organ-like cover is removed from the structure, eliminating the source of noise generated by its movement and abrasion. The structural stability is maintained through the modular connection of the upper conveying unit and lower frame using simple, stable connection interfaces.
Solution Approach 2:
The belt supporting plate and side plates form a flexible yet stable framework that adapts to operational forces without generating noise. This flexible structure maintains structural stability while avoiding the noise problems of rigid, complicated connection structures.

AI summary
A cross belt sorting trolley, comprising an upper conveying unit (100) and a lower frame (200). A folding plate (7) is horizontally mounted on the side of each side plate (5). A first bending connecting plate (8) or a second bending connecting plate (9) is vertically connected to the side of each side plate (5). The folding plate is an integral horizontal plate-like component. A plurality of uniform circular arc-shaped sections (103) are arranged on the outer side edge of the folding plate. The circular arc-shaped sections of the folding plates on both sides of the same sorting trolley engage with each other. A plurality of groups of folding plate fixing plates (6) are mounted on the side portion of the side plate. The folding plate fixing plates are provided with bending portions. The side portions of the folding plate fixing plates are fixedly connected to the side plates. Horizontal tops of the folding plate fixing plates are fixedly connected to the folding plate. The first bending connecting plate and the second bending connecting plate are respectively connected to side plates on one side. Respective modular structures of the upper conveying unit and the lower frame of the trolley are improved, and grouping opposing connection modules are also used in terms of the interconnection construction of the upper conveying unit and the lower frame, which improves the mounting stability and the accuracy of the assembly and disassembly of module structures of assemblies, simplifies the disassembly operation efficiency, and reduces the abrasion between components, and the operating noise.
