Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If waste collection vehicles use traditional collection methods without weighing systems, then the vehicle structure remains simple and cost-effective, but accurate measurement of collected materials cannot be achieved
Solution Approach 1:
The weighing system is nested within the collection bin structure, with load cells integrated into the bin's support framework. The collection bin itself serves as the weighing platform, eliminating the need for separate weighing mechanisms and reducing overall system complexity while maintaining measurement accuracy.
Solution Approach 2:
The collection bin performs dual functions: it serves as both the container for collecting waste materials and as the weighing platform for measuring the weight of collected materials. This multi-functionality eliminates the need for separate weighing equipment, reducing system complexity while achieving accurate weight measurement.
2Measurement precision
If a weighing system is added to waste collection vehicles, then accurate weight measurements can be achieved, but the device complexity and cost increase
Solution Approach 1:
The load cells are integrated into the existing collection bin structure rather than being added as separate components. The bin's support legs or frame members incorporate the load cell elements, allowing the weighing functionality to be manufactured as part of the bin assembly process, thereby reducing manufacturing complexity.
3Measurement precision
If traditional collection bins are used without suspension mechanisms, then the bin structure remains simple, but accurate weight measurements during vehicle movement cannot be achieved
Solution Approach 1:
The suspension mechanism serves dual purposes: it provides mechanical support and shock absorption for the collection bin during vehicle operation, and simultaneously functions as the mounting structure for the weighing system. This eliminates the need for separate suspension and weighing support structures, reducing overall system complexity.
4Productivity
If weight measurements are not associated with container data, then data management remains simple, but efficient recycling tracking and charging by weight cannot be implemented
Solution Approach 1:
The system automatically captures weight measurements and associates them with container identification data (such as RFID tags or barcode scanners on containers). This automated feedback loop eliminates manual data entry, ensures accurate tracking of recyclables by weight, and enables efficient charging systems without requiring complex manual data management procedures.
