Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If multiple vehicle electrical appliances are connected to the vehicle battery, then the appliances can be powered, but the connecting wires become complex and the space occupation increases
Solution Approach 1:
The system is segmented into a mobile power supply unit and separate appliance modules. Each appliance can be independently connected to the mobile power supply, eliminating the need for complex wiring to the vehicle battery. The mobile power supply acts as an independent power source that can serve multiple appliances simultaneously without requiring intricate wiring arrangements.
Solution Approach 2:
The mobile power supply serves as an intermediary between the vehicle battery and the electrical appliances. Instead of directly connecting multiple appliances to the vehicle battery (which creates wiring complexity), the mobile power supply receives power from the vehicle battery and then distributes it to multiple appliances, simplifying the overall wiring structure.
2Use of energy by moving object
If multiple vehicle electrical appliances are connected to the vehicle battery, then the appliances can operate, but the space occupation increases and storage becomes inconvenient
Solution Approach 1:
The system divides the electrical appliance system into separate modular units (mobile power supply and appliance modules). This segmentation allows each component to be compact and independently sized, reducing the total volume required compared to a single integrated system or multiple separate hardwired appliances.
Solution Approach 2:
The system transitions from a fixed, hardwired configuration to a dynamic, detachable modular configuration. The mobile power supply and appliance modules can be connected and disconnected as needed, allowing the system to adapt its physical presence in space. When not in use, the modules can be separated and stored independently, reducing space occupation.
3Adaptability or versatility
If traditional vehicle electrical appliances are designed, then they can provide various functions, but the size and weight are large making storage difficult
Solution Approach 1:
The appliance system is segmented into a mobile power supply unit and separate functional modules (inflation pump, dust collector, lighting lamp, air purifier, vehicle washer, mobile phone supporter). Each module contains only the specific functional components needed for its purpose, eliminating redundant weight. The modular design allows users to only carry and connect the specific appliance modules they need for each task, rather than transporting a single large multi-functional unit.
Solution Approach 2:
The mobile power supply serves as a universal base unit that can power multiple different types of appliance modules. This multi-functionality is achieved through standardized connecting parts that allow different modules to interface with the same power supply, reducing the need for multiple specialized power supply units and thereby reducing overall weight.
4Adaptability or versatility
If multiple separate electrical appliances are designed, then each can perform its specific function, but the production cost increases
Solution Approach 1:
The system is segmented into a common mobile power supply unit and separate appliance modules. This segmentation allows for standardized manufacturing of the power supply unit, which can be produced in larger quantities and thus benefit from economies of scale. The appliance modules can be manufactured separately and then assembled with the power supply unit, simplifying the manufacturing process and reducing tooling costs compared to producing multiple complete integrated appliances.
Solution Approach 2:
The mobile power supply unit merges common components (power battery pack, circuit control board, mounting part with snap structure and electrical interfaces) that are shared across all appliance modules. This merging of common elements into a single reusable unit reduces the total component count and production cost compared to having separate complete appliances for each function.
