Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a closed cavity arm structure is used in VTOL UAS, then structural strength and compactness are improved, but heat dissipation capability deteriorates
Solution Approach 1:
The closed cavity arm structure is modified by introducing porous features in the form of air inlet holes and air outlet holes. These holes create a porous pathway through the arm structure, allowing air to flow through and carry heat away from the motor and electronic speed controller, thus improving heat dissipation while maintaining the structural integrity of the closed cavity design
Solution Approach 2:
The invention uses air flow (pneumatics) as the cooling medium. Air is drawn in through the air inlet holes, passes through the hollow interior of the arm structure where it absorbs heat from the equipment, and is then expelled through the air outlet holes. This pneumatic cooling system effectively removes heat from the closed cavity structure without compromising its strength
2Device complexity
If no heat dissipation equipment is installed in the arm, then device complexity is reduced, but equipment reliability deteriorates due to overheating
Solution Approach 1:
The arm structure itself is made to serve the dual function of structural support and heat dissipation. By incorporating air inlet and outlet holes directly into the arm structure, the system uses its own structure as the heat dissipation pathway, eliminating the need for separate cooling systems or additional components. The arm structure performs self-cooling through natural air flow through its porous features
Solution Approach 2:
The arm structure is designed to perform multiple functions simultaneously: it provides structural support for the motor and electronic speed controller, serves as a hollow interior space for equipment mounting, and acts as a heat dissipation channel through its porous air inlet and outlet holes. This multi-functionality reduces overall system complexity while improving reliability
