Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a current conveying system is used, then the structure is simple, but the conveying speed is slow and high-beat production cannot be achieved
Solution Approach 1:
The conveying system is divided into multiple independent layers, with each layer having its own trolley and driving assembly. This segmentation allows parallel operation of multiple trolleys on different layers, significantly increasing the overall conveying capacity and speed without requiring a single complex high-speed mechanism
Solution Approach 2:
The system transitions from a single-layer conveying structure to a multi-layer spatial structure. By adding the vertical dimension with multiple layers connected by lifting devices, the system achieves high-speed conveying and high-beat production through parallel processing on different levels, effectively increasing throughput without proportionally increasing horizontal space or complexity
2Manufacturing precision
If a current conveying system is used, then the structure is simple, but positioning accuracy is low and trolley deviation occurs
Solution Approach 1:
Positioning assemblies are introduced as intermediary devices between the trolley and the guide rails. These positioning assemblies include positioning wheels that contact the guide rails to constrain trolley movement, providing accurate positioning without requiring the entire conveying system to be highly complex
Solution Approach 2:
The system replaces reliance on purely mechanical precision of the guide rails with a hybrid approach combining mechanical guide rails and mechanical positioning assemblies. The positioning assemblies act as adjustable mechanical correctors that compensate for guide rail imperfections, achieving high positioning accuracy without requiring extremely precise mechanical manufacturing throughout the entire system
3Weight of moving object
If a current conveying system is used, then the structure is simple, but the system cannot convey heavy workpieces
Solution Approach 1:
Multiple trolleys on different layers are merged into a single integrated multi-layer conveying system. The lifting devices connect the layers, allowing the system to collectively handle heavy workpieces by distributing the load across multiple support points and utilizing the combined capacity of all layers
Solution Approach 2:
By adding the vertical dimension with multiple layers, the system increases its load-bearing capacity. Heavy workpieces can be conveyed on any layer, and the multi-layer structure allows parallel conveyance of multiple heavy workpieces simultaneously, effectively multiplying the system's total weight handling capability without proportionally increasing the complexity of individual components
