Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the power supply assembly is integrated with the functional assembly in the same direction, then the device structure is compact, but aerosols and condensates can flow and contact electronic components causing safety hazards
Solution Approach 1:
The patent changes the spatial arrangement from a linear same-direction layout to a perpendicular multi-dimensional layout. The power supply assembly is positioned in the second direction (perpendicular to the first direction of the functional assembly), creating spatial separation that prevents aerosol flow paths from reaching electronic components while maintaining device compactness through efficient 3D space utilization.
2Duration of action of stationary object
If the power supply assembly and functional assembly are detachably connected, then the service life of the power supply assembly is increased, but the device complexity increases due to additional connection mechanisms
Solution Approach 1:
The device is divided into separable functional assembly and power supply assembly modules. This segmentation allows the power supply assembly to be detached and replaced independently after use, extending its service life through multiple reuse cycles while the complexity is managed through standardized connection interfaces.
Solution Approach 2:
The connection between assemblies is achieved through magnetic attractive members that generate holding force, replacing complex mechanical fastening systems with a simpler magnetic field-based attachment mechanism that reduces structural complexity while maintaining secure connection.
3Strength
If attractive members are used to connect the power supply assembly and functional assembly, then the connection strength is increased, but the device complexity increases due to additional magnetic components
Solution Approach 1:
The attractive members (magnetic components) are integrated into the structural design of the assembly housings themselves, merging the connection function with the existing structural elements rather than adding separate complex magnetic attachment mechanisms, thereby increasing connection strength without proportionally increasing device complexity.
