Double-Chamber Inflatable Paddle Board with Detachable Fixing Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-chamber inflatable paddle boards have an unreasonable structure, complex manufacturing processes, high defect rates, and poor safety due to hard inner sealing strips and interconnected chambers, leading to safety hazards when one chamber leaks.
Innovation Solution
A double-chamber inflatable paddle board with a detachable design featuring independent outer and inner chambers connected by a polyvinyl chloride fixing connector strip, allowing for easy detachment and independent inflation/deflation, reducing the burden on the other chamber in case of a leak.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard inner sealing strips are thermally pressed together to form a two-chamber structure, then the chambers are tightly sealed, but the manufacturing process becomes complex and the defect rate increases
Solution Approach 1:
The paddle board is divided into two independent chambers (inner chamber and outer chamber) that can be manufactured separately. The inner chamber is placed within the outer chamber, and they are connected through a detachable fixing connector strip rather than being bonded together, simplifying the manufacturing process while maintaining sealing reliability.
Solution Approach 2:
A fixing connector strip serves as an intermediary component between the inner and outer chambers. This connector strip with accommodating cavity allows the chambers to be connected without requiring hard thermal pressing, thereby reducing manufacturing complexity while ensuring reliable sealing through the intermediary connection mechanism.
2Stability of the object's composition
If the two chambers are bonded together through inner layer airtight strips, then the structure is formed, but the leaking chamber becomes a burden on the other chamber, reducing safe buoyancy
Solution Approach 1:
The paddle board structure is segmented into independently functional chambers. The inner chamber and outer chamber are separated by a detachable connection rather than being permanently bonded, allowing one chamber to be deflated or removed without compromising the other chamber's buoyancy and structural integrity.
Solution Approach 2:
The connection between chambers is made dynamic through a detachable fixing connector strip rather than static bonding. This allows the chambers to be independently inflated, deflated, or separated as needed, enabling the system to adapt to leakage situations and maintain safe buoyancy by isolating the affected chamber.
3Reliability
If one chamber leaks, the other chamber experiences curving trend due to force changes at bonding points, but with detachable design the leaking chamber can be separated
Solution Approach 1:
The paddle board is divided into separate chambers connected by a detachable fixing connector strip. When leakage occurs, the detachable connection allows the leaking chamber to be separated from the intact chamber, preventing force transmission that would cause curving deformation and maintaining structural safety.
Solution Approach 2:
The leaking chamber can be extracted or removed from the overall structure through the detachable connection mechanism. This extraction prevents the leakage issue from affecting the other chamber, eliminating the curving trend and maintaining the safety and structural integrity of the remaining chamber.
4Reliability
If inner layer airtight strips are thermally pressed to form sealed chambers, then the chambers are independent, but the bonding process is difficult and defect rate is high
Solution Approach 1:
A fixing connector strip with accommodating cavity serves as an intermediary component that simplifies the bonding process. Instead of directly bonding inner layer airtight strips together through thermal pressing, the connector strip mediates the connection between chambers, making the bonding process easier and reducing manufacturing defects while maintaining chamber independence.
Solution Approach 2:
The connection method transitions from high-temperature thermal pressing to a mechanical attachment system using the fixing connector strip. This parameter change in the bonding process (from thermal to mechanical) reduces the difficulty of bonding and lowers the defect rate while preserving the independence of the chambers.

AI summary
A double-chamber inflatable paddle board with detachable function includes an outer chamber, an inner chamber and a fixing connector strip. The outer and inner chambers are independent chambers. A middle portion of the outer chamber includes an opening with an accommodating cavity that matches the inner chamber. One side of the fixing connector strip is fixedly connected to one of an inner edge of the outer chamber and an outer edge of the inner chamber, and the other side is suspended. In an inflated state, the other side of the fixing connector strip is engaged on one of the outer edge of the inner chamber and the inner edge of the outer chamber, to cooperate with the connected chamber to form an inflatable paddle board product with flat surface. The inner and outer chambers are detachably connected into one piece through the fixing connector strip.
