Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fan product is integrated with the lighting function of a lamp, then the lighting and blowing functions are combined, but the packaging size becomes oversized occupying a lot of space in storage and transportation
Solution Approach 1:
The main body frame is divided into multiple split frames that can be detached from each other. The fan component is separated into a rotating piece and multiple fan blades that can be detached. This segmentation allows the components to be disassembled and packaged in a compact manner, reducing the packaging volume while maintaining the integrated lighting and blowing functions when assembled.
Solution Approach 2:
The lamp brackets are designed with foldable structures that can be dynamically adjusted between extended and folded positions. This dynamic design allows the lamp brackets to be folded into a compact configuration during packaging, significantly reducing the overall packaging size while maintaining full functionality when in the extended position.
2Volume of moving object
If the packaging size is reduced through disassembly and folding, then storage and transportation costs are lowered, but the device complexity increases due to multiple detachable connections
Solution Approach 1:
Multiple connection functions are merged into integrated connecting structures. The connecting pieces incorporate both connection and limitation functions in a single component design. For example, the connecting pieces have protrusions that fit into corresponding grooves on adjacent split frames, combining the connection action with the limitation action in one structural element, thereby reducing the number of separate components needed.
Solution Approach 2:
The connecting structures are designed with localized features tailored to specific connection points. Each connecting piece has protrusions and grooves positioned at specific locations on the split frames to achieve both connection and limitation functions. This localized design approach allows for simple, targeted connection mechanisms rather than complex universal joints, reducing overall device complexity.
3Volume of moving object
If the fan blades are detachably connected to the rotating piece, then the packaging compactness is improved, but the manufacturing precision requirements increase for the connection interfaces
Solution Approach 1:
The fan component is segmented into a rotating piece and multiple fan blades with detachable connections. This segmentation allows for standardized connection interfaces that can be manufactured with controlled precision, and the modular design permits assembly and disassembly without requiring extremely tight tolerances across the entire assembly, thereby reducing the overall manufacturing precision requirements while maintaining packaging compactness.
Solution Approach 2:
The connection design incorporates multi-dimensional features including protrusions that fit into grooves, mounting holes for locking pieces, and limiting grooves with protrusion limiting structures. This multi-dimensional connection approach provides multiple degrees of freedom and constraint points, allowing for easier assembly and reduced sensitivity to manufacturing precision in any single dimension, thereby lowering the overall precision requirements.
