Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inflatable products with multiple chambers face issues of high costs due to multiple air pumps, complex structures, and inefficient inflation control that can lead to over-expansion of secondary chambers, potentially causing damage.
Innovation Solution
A line-controlled air pump with a movable L-shaped switching pipe and pressure sensor system that controls air flow to each chamber independently, considering volume differences to prevent over-expansion and optimize inflation/deflation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate air pumps are installed for each chamber, then each chamber can be inflated and deflated independently, but the cost and device complexity increase significantly
Solution Approach 1:
The air pump system is segmented into functional modules: a single air pump unit combined with individual valve controls for each chamber. This allows independent control of each chamber through separate valves while using one air pump, reducing complexity while maintaining adaptability.
Solution Approach 2:
A single air pump is designed to serve multiple chambers through a universal valve control system. The air pump can inflate or deflate any chamber by controlling the valve connections, making one pump perform the function of multiple dedicated pumps.
2Device complexity
If a single air pump with multiple internal air flow channels is used, then device complexity is reduced, but the structure becomes relatively complex and inflation control becomes inefficient
Solution Approach 1:
The system uses dynamic valve control to switch air flow channels based on operational needs. Instead of fixed internal channels, the valves dynamically connect the air pump to different chambers, enabling efficient and flexible inflation control for each chamber independently.
3Ease of operation
If all chambers are inflated simultaneously until completion, then inflation process is simple, but secondary chambers become over-expanded while main chamber remains insufficiently inflated
Solution Approach 1:
The inflation process is segmented into sequential stages for each chamber. The control system activates one chamber at a time, allowing precise control over the inflation process for each chamber independently, preventing over-expansion of secondary chambers while ensuring proper inflation of the main chamber.
Solution Approach 2:
The control system determines the inflation sequence in advance based on chamber volume differences. Smaller secondary chambers are inflated first to their appropriate volume, then the main chamber is inflated separately, ensuring each chamber reaches its optimal expansion state without over-inflation.
4Productivity
If continuous air output is maintained for all chambers, then inflation completion is achieved, but service life of secondary chambers is reduced and rupture may occur
Solution Approach 1:
The inflation process is divided into separate control cycles for each chamber. After each chamber reaches its target volume, the air flow to that chamber is stopped while other chambers continue to be inflated. This segmented approach prevents continuous air output to all chambers, maintaining chamber integrity and extending service life while achieving complete inflation.

AI summary
A line-controlled air pump for multi-chamber inflatable products includes an L-shaped switching pipe movably disposed inside the air pump and a pressure sensor configured to detect pressure data of the inflatable product. When the pressure sensor detects that the pressure data has risen to the preset first threshold, inflation of each secondary chamber of the inflatable product suspends while inflation of the main chamber maintains. When the pressure sensor detects that the pressure data has risen to a preset second threshold, the control system stops inflation of the main chamber of the inflatable product, while the control system continues inflation of each secondary chamber. When the pressure sensor detects that the pressure data has risen to a preset third threshold, the control system stops inflation of both the main chamber and each secondary chamber.
