Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional fan structure is used, then the fan can provide cooling function, but it takes up a lot of space and is not easy to store
Solution Approach 1:
The fan is divided into separable components including the fan body, support base with leg tubes, and mounting base. These segments can be detached and reconfigured for compact storage or stable deployment, resolving the contradiction between functional completeness and storage compactness
Solution Approach 2:
The support base incorporates deformable leg tubes that can change shape between extended (for stability during use) and retracted (for compact storage) states. This dynamic transformation allows the fan to adapt its volume according to operational requirements
2Reliability
If a conventional fan structure is used, then the fan can operate, but it is not easy to support and fix during use
Solution Approach 1:
The support function is separated into the mounting base and leg tubes that can be independently adjusted and fixed. This segmentation allows the support structure to be optimized for stability while maintaining ease of setup through modular assembly
Solution Approach 2:
The leg tubes can change their shape and configuration parameters to provide optimal support stability. By adjusting the extension and positioning of leg tubes, the fan achieves reliable support on various surfaces while keeping the setup process simple
3Adaptability or versatility
If a fixed-direction fan is used, then the structure is simple, but the blowing range is limited
Solution Approach 1:
The fan incorporates an oscillation mechanism that dynamically changes the blowing direction. The oscillation motor enables the fan head to rotate back and forth, expanding the effective cooling range without requiring multiple fixed fans, thus achieving adaptability with moderate complexity increase
Solution Approach 2:
The oscillation mechanism allows a single fan unit to serve multiple directional zones, making it universally applicable for larger spaces. This multi-functionality achieves extended blowing range while keeping the overall device structure relatively compact and manageable
