Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the water reservoir is installed at an offset position to accommodate the steam generating unit, then the steam generating unit can be installed inside the brush main body, but the storage capacity of the water reservoir is limited and the weight is not uniformly distributed
Solution Approach 1:
The water reservoir transitions from a two-dimensional planar layout to a three-dimensional structure that utilizes vertical space. By forming the bottom wall with multiple levels having different heights, the reservoir creates a multi-level storage structure that increases capacity without expanding the horizontal footprint, thus accommodating the steam generating unit while maximizing water storage.
2Temperature
If the water reservoir is installed at an offset position, then the steam generating unit can be installed inside the brush main body, but the weight is not uniformly distributed to both sides
Solution Approach 1:
The bottom wall of the water reservoir is designed with asymmetric multi-level heights, where different portions have different elevations. This asymmetric structure allows the heavier water reservoir to be positioned in a way that balances the overall weight distribution of the brush main body, counteracting the offset placement of the steam generating unit and achieving uniform weight distribution.
3Ease of manufacture
If the floor of the water reservoir is formed as a single surface having a constant height, then the structure is simple, but water cannot be discharged through the discharge port when the brush main body is inclined
Solution Approach 1:
The bottom wall of the water reservoir is designed with multiple levels having different heights, creating a dynamic water flow path. When the brush main body is inclined, gravity causes water to naturally flow from higher levels to lower levels and discharge through the discharge port. This dynamic structure ensures water discharge functionality under various operating conditions while maintaining relatively simple manufacturing.
4Ease of manufacture
If the floor of the water reservoir is seated on the docking protrusion, then the discharge port structure is formed, but the storage capacity of the water reservoir cannot be increased
Solution Approach 1:
The water reservoir bottom wall is designed with multi-level heights, transforming the storage structure from a single-plane configuration to a multi-level three-dimensional structure. This allows the reservoir to utilize vertical space more effectively, increasing water storage capacity while maintaining the discharge port structure formed by the docking protrusion.
