Solution Overview
Problem
Existing inflatable devices are either labor-consuming and unsanitary for manual inflation or inconvenient due to their large size and power requirements, especially for public use products like inflatable pillows.
Innovation Solution
A compact inflating device with a simple structure that allows manual inflation without electricity, featuring a valve body with integrated gas intake and exhaust valves, and a gas storage chamber, enabling easy operation and deflation without power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an electric compressor is used for inflation, then inflation efficiency is improved, but device volume increases and portability deteriorates
Solution Approach 1:
The device separates the inflation function from the compressor, using a hand-operated pump instead. The pump can be detached and stored separately, allowing the main device to remain compact while still providing efficient inflation capability when needed.
Solution Approach 2:
The solution moves from a single integrated electric compressor to a distributed system where the pumping action is external and manual, eliminating the need for a large built-in compressor while maintaining inflation effectiveness.
2Power
If an electric compressor is used for inflation, then inflation power is improved, but power supply requirements increase
Solution Approach 1:
The device uses manual hand pumping instead of electric power, making the system self-sufficient without requiring external power sources. The user's physical effort directly powers the inflation process, eliminating all power supply requirements.
3Device complexity
If mouth blowing is used for inflation, then device complexity is reduced, but hygiene deteriorates and labor consumption increases
Solution Approach 1:
The hand-operated pump serves as an intermediary between the user and the inflatable product. It provides a mechanical interface that maintains hygiene by preventing direct contact between the user's mouth and the product, while still enabling efficient inflation through manual operation.
4Productivity
If a specialized inflation instrument is used, then inflation efficiency is improved, but ease of operation deteriorates
Solution Approach 1:
The hand-operated pump is a universal tool that can inflate various types of products. Its simple, familiar design makes it easy to operate for anyone, while still providing sufficient inflation efficiency for the intended applications.
