Solution Overview
Problem
Handheld air pumps for sports balls are inefficient in achieving precise inflation pressure and often cause damage due to torsion, leading to unsatisfactory player experience and potential injury.
Innovation Solution
An electronic air pump with a cylindrical main body casing, a recessed casing, and a cap that securely houses a needle, featuring a magnetic on/off mechanism, LED pressure display, and manual/automatic mode operation, allowing for precise pressure control and protection of the needle during storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hand held air pumps are used to pressurize sports balls, then the balls can be inflated, but the pressurization process is slow and it is difficult to determine if the correct pressure is achieved
Solution Approach 1:
The patent combines the air pump function with a digital pressure gauge into a single integrated device. The pressure sensor and display are built into the pump housing, allowing simultaneous pressurization and real-time pressure monitoring without requiring separate instruments.
Solution Approach 2:
The pump automatically measures and displays its own output pressure through an integrated pressure sensor and digital display. The system self-monitors the pressurization process and provides real-time feedback to the user, eliminating the need for external measurement tools.
2Ease of operation
If hand held air pumps are used to pressurize sports balls, then the balls can be inflated, but torsion is introduced causing inflation needles to bend and/or snap off
Solution Approach 1:
The pump features a flexible, jointed needle assembly that can bend and adapt to the curvature of the sports ball surface. The needle includes elastic segments that allow it to flex during insertion and pressurization, preventing breakage from rigid torsional stresses.
Solution Approach 2:
The needle material and structural parameters are optimized to balance flexibility and strength. The needle is designed with specific elastic properties that allow it to deform under stress without permanent deformation or failure, adapting to different ball surfaces while maintaining sealing effectiveness.

AI summary
An electronic air pump pressurizes object in either manual or automatic mode. In automatic mode, the electronic air pump determines air pressure needed to adjust an object to a set target pressure. The electronic air pump inflates or deflates the ball automatically until the air pressure inside the ball matches the preset value. In manual mode regulation of the air pressure is adjusted by a user.
