Electrical Inflator With Integrated LED Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional manual inflators are cumbersome to use due to their reduced volume, requiring excessive physical effort for inflation and lack illumination, making it difficult to operate in low-light conditions.
Innovation Solution
An electrical inflator with a cylindrical shell, an electrical aeration pump, an illumination assembly, a cell base, and a switch assembly, which includes a light-emitting diode (LED) for illumination and a gear mechanism for efficient inflation, allowing for easier handling and operation in low light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the volume of manual inflator is minimized for lightweight and portability, then portability is improved, but ease of operation deteriorates as users have to spend lots of time and physical efforts on inflating tires
Solution Approach 1:
The patent replaces the manual mechanical pumping system with an electrical aeration pump. The electrical pump uses electromagnetic force to drive the piston, eliminating the need for users to manually operate a lever or pump mechanism. This substitution maintains the compact portable design while dramatically reducing physical effort and time required for inflation operations.
2Volume of stationary object
If the volume of manual inflator is minimized, then portability is improved, but illumination function is lost making it difficult to connect air nozzle at night or dusky places
Solution Approach 1:
The patent merges two previously separate functions into a single integrated device: the portable inflator and the illumination light. The electrical pump and LED illumination assembly share the same power source (rechargeable battery) and housing, creating a multi-functional device that provides both inflation and lighting capabilities without significantly increasing overall volume.
Solution Approach 2:
The device achieves multi-functionality by incorporating both an electrical aeration pump for tire inflation and an LED illumination assembly for lighting. The single rechargeable battery powers both functions, allowing users to perform both inflation and illumination tasks with one portable device, eliminating the need for separate tools.
3Device complexity
If manual inflator lacks illumination function, then device complexity is reduced, but ease of operation deteriorates in low light conditions
Solution Approach 1:
The patent replaces potential complex mechanical illumination mechanisms (such as bulbs requiring separate power sources or complex switching systems) with simple LED technology. LEDs provide efficient, long-lasting illumination with minimal electrical power, maintaining low device complexity while dramatically improving ease of operation in low-light conditions.
