Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the motor bracket is designed as a solid structure to provide support and mounting functionality, then structural strength and stability are improved, but air flow obstruction increases and ventilation area decreases
Solution Approach 1:
The motor bracket is designed with air holes penetrating through its structure, transforming it from a solid opaque block to a porous-like structure that allows air passage. This resolves the contradiction by maintaining the bracket's mechanical strength while creating pathways for air flow, effectively increasing the ventilation area without compromising structural integrity.
Solution Approach 2:
The motor bracket structure is segmented by introducing air holes that divide the solid structure into regions separated by thin walls. This segmentation allows the bracket to maintain its overall structural strength while creating multiple air flow channels, thereby increasing the effective ventilation area.
2Device complexity
If the motor bracket is positioned close to the vent for compact design, then device complexity is reduced, but air flow resistance increases
Solution Approach 1:
By making the motor bracket porous with air holes, the patent allows the bracket to be positioned close to the vent without creating excessive air flow resistance. The air holes enable air to pass through the bracket itself, reducing the harmful resistance effect while maintaining the compact design.
3Productivity
If the motor bracket is designed with air holes to increase ventilation area, then heat exchange efficiency is improved, but structural strength may be compromised
Solution Approach 1:
The air holes are strategically positioned and sized to create local openings that do not compromise the overall structural strength of the motor bracket. The local quality of the bracket is modified only where necessary for air passage, while the rest of the structure maintains its strength to support the motor and withstand operational loads.
