Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a big reservoir with high-pressure source and multiple pipes is used to change fuel, then fuel can be drained or refilled, but the device becomes complicated, large in size, and costly
Solution Approach 1:
The device is divided into separate functional modules: a barrel for fuel storage, a plunger mechanism for fuel transfer, and an adapting mechanism with interchangeable adapters for different fuel connectors. This segmentation allows each component to be simple and independent, avoiding the need for a complex integrated system with multiple pipes and high-pressure sources.
Solution Approach 2:
The adapting mechanism acts as an intermediary between the fuel can and various fuel pipe connectors. By using detachable adapters that can be selectively connected, the device can accommodate different connector types without requiring multiple dedicated connection systems, thus simplifying the overall structure.
2Reliability
If a big reservoir with multiple pipes is used, then fuel changing is possible, but the device is large and has limited storage and operation environments
Solution Approach 1:
The fuel changing device is segmented into compact modular components that can be stored separately or assembled as needed. The barrel, plunger, and adapting mechanism can be disassembled and stored in small spaces, making the device suitable for portable applications and limited storage environments.
Solution Approach 2:
The device incorporates movable and detachable components, including the plunger that can be inserted or removed from the barrel, and adapters that can be selectively attached to the adapting mechanism. This dynamic configuration allows the device to be compact when not in use and fully functional when assembled.
3Reliability
If a complicated device with multiple pipes is used, then fuel can be drained or refilled, but it is difficult to operate
Solution Approach 1:
The complex high-pressure source and multiple pipe systems are extracted and replaced with a simple plunger mechanism that transfers fuel through direct mechanical displacement. This extraction of unnecessary complexity leaves only the essential fuel transfer function, making the device easy to operate.
Solution Approach 2:
The adapting mechanism is designed to be self-adjusting through selective adapter connection. The user simply attaches the appropriate adapter to match the fuel connector type, and the system automatically configures itself for the correct connection, eliminating the need for complex manual setup or adjustment procedures.
4Reliability
If a conventional fuel changing device with multiple pipes is used, then fuel can be changed, but it costs a lot
Solution Approach 1:
The device uses simple, mass-producible components such as a basic cylindrical barrel, a straightforward plunger mechanism, and interchangeable adapters. These segmented components can be manufactured independently using standard machining processes, reducing tooling costs and assembly complexity compared to a custom-integrated multi-pipe system.
Solution Approach 2:
The adapting mechanism with interchangeable adapters provides universal compatibility with different fuel connector types. This multi-functionality eliminates the need to manufacture separate dedicated devices for each connector type, reducing overall manufacturing costs through component standardization and reuse.
