Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple connecting parts are used to form inflatable chambers, then the structural complexity increases, but the air-tightness and load-bearing capacity deteriorate
Solution Approach 1:
The patent merges multiple connecting parts into a single integrated support net structure that directly supports the inflatable chamber without requiring separate connection components. This integration reduces the number of potential leakage points while maintaining structural integrity, thereby improving air-tightness without significantly increasing structural complexity.
Solution Approach 2:
The support net is segmented into multiple strands arranged in a grid pattern, which distributes the load across multiple points while maintaining overall structural integrity. This segmentation allows the structure to bear load effectively without requiring numerous connection parts, thus maintaining air-tightness.
2Device complexity
If multiple connecting parts are used to form inflatable chambers, then the structural complexity increases, but the load-bearing capacity deteriorates
Solution Approach 1:
The support net is pre-formed with a specific grid structure before assembly, which optimizes its load-bearing capability. This preliminary structuring ensures that the support net can effectively distribute and bear loads without requiring additional connection parts, thereby maintaining high load-bearing capacity while reducing structural complexity.
Solution Approach 2:
The support net is constructed using composite material structures that combine strength and flexibility. This composite construction allows the support net to bear loads effectively while maintaining a simple overall structure without requiring numerous connection parts, thus improving load-bearing capacity without increasing structural complexity.
3Ease of manufacture
If edge stitching is used to connect parts, then the production process becomes simpler, but the sealing quality deteriorates
Solution Approach 1:
The patent replaces mechanical edge stitching with a scaling connection method that uses thermal or chemical bonding. This substitution eliminates the need for needles and threads while achieving superior sealing quality through more reliable bond strength, thus maintaining production simplicity while significantly improving sealing precision.
Solution Approach 2:
The connection method transitions from mechanical (stitching) to thermal or chemical parameters (scaling). This parameter change enables better sealing quality through controlled bonding processes while maintaining ease of manufacture, as the scaling process can be efficiently integrated into existing production workflows.
4Ease of operation
If many connecting points are provided, then the ease of assembly improves, but the yield rate deteriorates due to poor sealing and strength
Solution Approach 1:
The patent merges multiple connection points into a single integrated support net structure that provides both structural support and sealing functions. This integration reduces the total number of connection points required, thereby improving yield rate by reducing failures at connecting points while maintaining ease of assembly through the unified structure.
Solution Approach 2:
The support net serves multiple functions simultaneously: structural support, sealing, and load distribution. This multi-functionality eliminates the need for separate connection components, reducing the number of potential failure points and improving yield rate while maintaining ease of assembly through the versatile design.

AI summary
A water float includes a first part sheet, a middle part sheet, and a second part sheet. The three sheets are three parts of a single original sheet. The first part sheet and the second part sheet are respectively folded and sealingly connected to form a first and second inflatable floating chamber. The first inflatable floating chamber and the second inflatable floating chamber are configured to provide buoyancy in water, while the middle part sheet is configured to support user. When in use, fold and flip the first and second part sheet along centerline, stacking the first and second part sheet on top of each other, and then seal each edge of the first and second part sheet to form the sealed first and second inflatable floating chamber. A method for manufacturing a water float is also provided.
