Portable Electric Inflator Shock Absorbing End Cover Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflators are often too large and not compact enough for easy carrying and storage, and their bottom designs lack anti-shock features, leading to vibration and friction noise, as well as potential wear and detachment of anti-shock pads due to exposure to dust or rain.
Innovation Solution
A portable electric inflator with a compact design, featuring a housing with a shock absorbing end cover that is integrally formed with soft and hard rubber, providing effective shock absorption and anti-slip properties, and an L-shaped battery assembly that optimizes space usage within the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional inflators use glued anti-shock pads on the bottom, then anti-shock function is provided, but the pads may detach when exposed to dust or rain due to adhesive failure
Solution Approach 1:
The patent merges the anti-shock pad with the housing by integrating them into a single molded component. The housing includes a bottom surface with an integrated anti-shock pad structure, eliminating the need for separate adhesive attachment. This unified design ensures the anti-shock pad remains firmly attached under all environmental conditions while maintaining the protective function.
2Ease of operation
If conventional inflators are designed with basic functionality, then they can inflate tires and balls, but they are too large in size and not compact enough for easy carrying and storage
Solution Approach 1:
The patent implements nesting by placing the battery assembly inside the housing structure. The battery assembly includes a battery body that fits within the housing's internal cavity, allowing the power source to be integrated rather than external. This nested arrangement reduces the overall volume and creates a compact, portable design while maintaining all necessary functions.
3Reliability
If conventional inflators lack integral anti-shock design, then manufacturing is simpler, but the firmness depends entirely on adhesive viscosity which fails under environmental exposure
Solution Approach 1:
The patent combines the housing and anti-shock pad into a single integrated component through molding. The housing includes a bottom surface with an integrated anti-shock pad structure that is formed as one piece during manufacturing. This eliminates the need for separate adhesive application and assembly steps, achieving both reliability and manufacturing efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compact and portable design enhances storage and carrying convenience, while the integral shock absorbing end cover reduces friction noise and wear, ensuring stability and longevity of the inflator.
Implementation Method 1
a shock absorbing end cover arranged at the lower end of the housing
Implementation Method 2
integrally formed with soft and hard rubber
Implementation Method 3
When the inflators are placed on the ground, vibration and friction noise is large
