Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices do not effectively simulate water sports like surfing, kayaking, and stand-up paddle boarding on dry land, lacking resistance mechanisms and wave simulation.
Innovation Solution
A dry land trainer with a resistance mechanism using cords or ropes, a confocal parabolic cylinder for wave simulation, and a display for real-time feedback, allowing users to perform water exercises from different positions and adjust resistance levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing exercise devices are used, then basic exercise functionality is provided, but they cannot simulate water sports conditions effectively
Solution Approach 1:
The exercise device is designed to simulate multiple water sports including kayaking, canoeing, and rowing using a single apparatus. The platform can accommodate different user positions (kneeling, sitting, lying) and different exercise types, making one device serve multiple functions that would traditionally require separate equipment for each water sport
Solution Approach 2:
A resistance mechanism using cords or ropes acts as an intermediary between the user's movements and the simulation of water resistance. These cords transmit and modify the user's physical effort to create the sensation of moving through water, bridging the gap between land-based exercise and water sport simulation
2Reliability
If a resistance mechanism is added to simulate water resistance, then exercise realism is improved, but device complexity increases
Solution Approach 1:
The resistance mechanism appears to be self-regulating, where the cords or ropes provide automatic resistance based on the user's pulling motion. The system uses the user's own movement to generate and modulate resistance, eliminating the need for complex electronic controls or manual adjustment mechanisms while maintaining realistic water resistance simulation
3Adaptability or versatility
If wave simulation is added using confocal parabolic cylinder, then exercise variety is improved, but device complexity increases
Solution Approach 1:
The platform incorporates dynamic movement capabilities through the confocal parabolic cylinder mechanism, allowing it to simulate wave motions and varying exercise conditions. This enables the platform to transition between different motion patterns and resistance levels, adapting to various water sport simulations without requiring multiple separate devices

AI summary
Improvements in a dry land training exerciser is disclosed that can simulate a variety of different water-based exercises while on dry land to allow simulation of surfing, kayaking, stand up paddle boarding and swimming by changing the top member platform. One or two cords or ropes operate on a retraction mechanism to produce a load to simulate the exercise. The top member exercise platform is mounted on a confocal parabolic cylinder that allows the exercise platform to simulate wave motion by altering the position and angle of the user as if going up and down a wave. The exerciser includes a display the user can view when exercising. The display can run a pre-recorded simulation of a prior water activity or can use motion of the user to calculate body position and movement to then generate an approximation of the outcome of the user on the water.
