Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual pressure sensing is used to control inflation pressure, then the air pump can be operated without additional sensors, but the pressure control becomes time-consuming and inaccurate
Solution Approach 1:
The patent replaces the manual mechanical pressure sensing method with an electronic pressure sensor and wireless control system. The pressure sensor automatically detects the internal pressure of the inflatable body and transmits data wirelessly to the controller, eliminating the need for manual pressing and visual estimation. This substitution of mechanical sensing with electronic sensing achieves precise automatic pressure control without time loss.
2Extent of automation
If wire-controlled or panel-controlled built-in air pumps are used, then automation is improved, but the control panel becomes inaccessible or unreliable when damaged
Solution Approach 1:
The patent extracts the control function from the built-in air pump and relocates it to a mobile terminal (smartphone or tablet). The control panel is no longer physically integrated into the air pump housing but is accessed remotely through wireless communication. This extraction makes the control system reliable even when the original control panel is damaged or inaccessible, as users can operate the air pump from anywhere within wireless range.
3Strength
If thermoplastic rubberized fabric is used for inflatable products, then the material is flexible and durable, but the internal pressure attenuates after inflation making constant pressure difficult to maintain
Solution Approach 1:
The patent implements a feedback control system where the pressure sensor continuously monitors the internal pressure of the inflatable body and transmits data to the controller. Based on this feedback, the controller automatically adjusts the air pump operation to maintain the preset pressure value. When pressure drops below the threshold, the system automatically inflates; when pressure reaches the target, the system stops. This closed-loop feedback mechanism compensates for the natural pressure attenuation of thermoplastic rubberized fabric, maintaining stable internal pressure over time.
4Device complexity
If manual operation is required for inflation and deflation, then the device structure remains simple, but the user experience deteriorates and product damage risk increases
Solution Approach 1:
The patent enables the air pump system to serve itself through automatic control. The pressure sensor continuously monitors pressure levels and the controller automatically activates the air pump for inflation or deflation based on preset parameters, without requiring user intervention. The system independently manages the entire inflation and deflation process, making operation as simple as setting the target pressure once. This self-service capability dramatically improves ease of operation while the modular wireless design keeps the added complexity manageable.
