Solution Overview
Problem
Inflatable stand-up paddle boards face challenges in efficient air inflation and deflation, as well as maintaining high internal pressure for user support, due to limitations in existing air pump integration and sealing mechanisms.
Innovation Solution
An integrated air pump system within the inflatable stand-up paddle board's body, featuring a casing with a detachable top cover and bottom cover, a rechargeable battery assembly, and a switching mechanism for air inlet and outlet control via vent holes, ensuring reliable air inflation and deflation while maintaining airtightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an external air pump is used for inflation, then the board can be inflated, but the inflation process is inefficient and requires separate attachment/detachment operations
Solution Approach 1:
The air pump is integrated into the board structure by placing it within the inflatable chamber, merging the inflation function with the board itself. This eliminates the need for separate attachment and detachment operations, allowing users to simply connect the air pump to the inflation valve for efficient inflation.
2Ease of operation
If the air pump is integrated into the board, then inflation becomes more convenient, but maintaining high internal pressure becomes more difficult
Solution Approach 1:
The inflatable chamber is segmented into two distinct spaces by an inner sheet: an air pump installation space and an inflatable chamber space. This segmentation isolates the air pump from the inflatable chamber, preventing air leakage between the two spaces while maintaining high internal pressure in the inflatable chamber during use.
3Productivity
If the air pump assembly is open, then air can be pumped in, but air leakage occurs and pressure is lost
Solution Approach 1:
The inner sheet acts as a flexible barrier that separates the air pump installation space from the inflatable chamber. This thin film structure maintains the airtightness of the inflatable chamber while allowing the air pump assembly to be open for efficient air pumping operations.
4Volume of moving object
If the board is deflated for storage, then storage space is reduced, but the deflation process is time-consuming
Solution Approach 1:
The integrated air pump system enables the board to be deflated quickly by simply operating the pump in reverse mode, which actively removes air from the inflatable chamber. This self-service deflation mechanism eliminates the need for complex manual deflation processes, reducing the time required to prepare the board for storage.
