Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function inflator pump is used, then the device structure is simple, but it lacks suction functionality requiring additional devices
Solution Approach 1:
The patent implements multi-functionality by integrating both inflation and suction capabilities into a single pump device. The pump body includes separate inlet and outlet ports that can be configured for different functions, and the piston mechanism can operate in reverse to achieve both inflation (pushing air out) and suction (pulling air in) operations, eliminating the need for separate devices
Solution Approach 2:
The patent employs a dynamic piston mechanism that can change its operational direction and mode. The piston is designed to move back and forth within the pump body, and by controlling the direction of piston movement and the opening/closing of valves, the system can switch between inflation mode (piston moves one direction) and suction mode (piston moves opposite direction), enabling a single device to perform multiple functions
2Adaptability or versatility
If additional suction devices are purchased, then suction functionality is achieved, but usage costs increase
Solution Approach 1:
The patent makes the pump device universal by enabling it to perform both inflation and suction functions. The pump body is designed with dual-purpose ports and a reversible piston mechanism, allowing users to achieve suction functionality without purchasing separate devices, thereby reducing overall usage costs while maintaining functional versatility
3Duration of action of stationary object
If traditional pump design is used, then manufacturing is simple, but heat dissipation is insufficient reducing service life
Solution Approach 1:
The patent introduces heat dissipation outlets as intermediary structures that provide a dedicated path for heat to escape from the pump body. These outlets act as mediators between the internal heat-generating components and the external environment, allowing efficient heat dissipation without complicating the core pumping mechanism, thereby extending service life while maintaining manufacturing simplicity
4Adaptability or versatility
If piston reciprocating mechanism is added, then dual functionality is achieved, but device complexity increases
Solution Approach 1:
The patent uses a dynamic piston mechanism that achieves dual functionality through reversible motion. The piston is designed to move back and forth within the pump body, and by controlling the direction of piston movement and the opening/closing of valves, the system can switch between inflation mode (piston moves one direction) and suction mode (piston moves opposite direction), enabling a single device to perform multiple functions without requiring completely separate mechanisms
Solution Approach 2:
The patent employs periodic reciprocating motion of the piston to achieve both inflation and suction functions. The piston moves in alternating directions in a cyclic manner, with each cycle comprising an inflation stroke and a suction stroke. This periodic action allows the single pump device to perform multiple functions by simply changing the direction and timing of piston movement, avoiding the need for complex multi-mechanism systems

AI summary
This application discloses an inflator pump and a one-way piston, including a housing. A cylindrical shell equipped with a drive mechanism is disposed in the housing, and an inclined swing piece, a piston, and a circular plate are disposed in the cylindrical shell. A top of the circular plate is provided with a piston hole, and the piston is disposed in the piston hole. A top of the circular plate is provided with a through hole, and a one-way valve is disposed in the through hole. This solution addresses the issue that most existing inflator pumps only have a single inflation function and lack the dual functionality of both suction and inflation, requiring the user to purchase an additional suction device, thus increasing usage costs.
