Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional swimming fins or monofins are used to enlarge the effective area of hands or feet, then propulsion through water is increased, but stability and swimming form are compromised, resulting in limited effectiveness
Solution Approach 1:
The device divides the propulsion function into separate components: the fuselage provides stability and houses the propulsors, while the stabilizer maintains balance. This segmentation allows each component to optimize its function without compromising overall stability, resolving the contradiction between propulsion force and swimming form stability.
Solution Approach 2:
The fuselage acts as an intermediary between the swimmer and the propulsors, providing a stable platform that translates the swimmer's leg movements into effective propulsion while maintaining proper body position. This intermediary structure prevents the instability caused by direct attachment of large propulsive surfaces to the limbs.
2Force
If monofins are used to provide unified propulsion, then some propulsion enhancement is achieved, but leg stability is compromised causing flailing motion
Solution Approach 1:
The device separates the propulsion function from the stability function by placing propulsors on the fuselage rather than directly on the legs. The stabilizer provides counterbalance to maintain leg stability, eliminating the flailing motion while preserving propulsion effectiveness.
3Area of moving object
If swimming fins are worn on each hand or foot, then the effective area is increased, but the device complexity and wearability are compromised
Solution Approach 1:
The device merges multiple functions into a single integrated unit: the fuselage combines propulsion surfaces, the stabilizer provides balance, and the connection mechanism attaches to the swimmer's lower body. This consolidation reduces device complexity compared to multiple separate fins while maintaining large effective area for propulsion.
