Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the air pump device is turned off after completing inflation, then energy consumption is reduced, but air pressure stability deteriorates due to gradual air leakage
Solution Approach 1:
The patent implements a feedback control mechanism where the air pressure sensor continuously monitors the internal air pressure of the inflatable product and sends signals to the control system. When the control system detects that air pressure has dropped below the preset threshold due to leakage, it automatically activates the air replenishing pump to restore pressure, thus maintaining reliability while the device remains in a low-power state.
Solution Approach 2:
The system performs self-service by automatically detecting air pressure changes and replenishing air without requiring user intervention. The control system, air pressure sensor, and air replenishing pump work together to autonomously maintain the inflatable product's air pressure, eliminating the need for manual monitoring and adjustment.

3Reliability
If the air replenishing pump is activated frequently to maintain air pressure, then air pressure stability is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control mechanism where the air pressure sensor continuously monitors the internal air pressure of the inflatable product and sends signals to the control system. When the control system detects that air pressure has dropped below the preset threshold due to leakage, it automatically activates the air replenishing pump to restore pressure, thus maintaining reliability while the device remains in a low-power state.
