Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If ventilation holes are provided in the head part, then air conditioning of the interior space is improved, but terminal shoots can grow through the holes and impair the device function
Solution Approach 1:
The ventilation opening is segmented into multiple smaller sub-openings by the blocking structure. This segmentation allows air to pass through multiple small paths while preventing terminal shoots from growing through, as the individual sub-opening dimensions are smaller than the shoot diameter.
Solution Approach 2:
The blocking structure acts as an intermediary element between the ventilation requirement and the shoot growth prevention requirement. It mediates by providing pathways small enough to block shoots but large enough to allow air flow, thus resolving the contradiction between ventilation and reliability.
2Reliability
If the head part is completely closed to prevent shoot growth, then device reliability is improved, but ventilation of the interior space deteriorates
Solution Approach 1:
The blocking structure introduces local quality variations in the head part wall. Instead of being uniformly closed or open, specific regions contain sub-openings with dimensions optimized for their dual function of allowing air flow while blocking shoot growth, thus resolving the contradiction between reliability and ventilation.
3Reliability
If blocking structures are added to ventilation openings, then terminal shoot growth through openings is prevented, but device complexity increases
Solution Approach 1:
The blocking structure is merged with the head part as a single integrated component. This combining of the blocking function with the existing ventilation opening structure avoids adding separate complex subsystems, thus minimizing the increase in device complexity while achieving the reliability improvement.
Solution Approach 2:
The blocking structure serves multiple functions simultaneously: it blocks terminal shoots from growing through, maintains ventilation by providing sub-openings for air flow, and can be integrated into the existing head part design. This multi-functionality reduces the need for additional separate components, thereby limiting complexity increase.
