Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportation vehicles lack the ability to seamlessly transition between water and land while providing efficient and engaging human-powered propulsion, failing to meet the needs of eco-conscious and adventurous users seeking versatile, multi-purpose vehicles that promote physical activity and social interaction.
Innovation Solution
A multiple-seat wagon design that integrates a first rowing and pedaling body assembly with a second water-buoyant assembly, allowing for effortless transition between water and land propulsion, using a first chassis assembly that demountably couples with a second chassis assembly and floating buoys for stability and buoyancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vehicle is designed for land use only, then it achieves optimal land mobility, but it cannot operate on water surfaces
Solution Approach 1:
The vehicle is divided into separable components: a land chassis with wheels and a water buoyant assembly with floating elements. These segments can be detached and reattached, allowing the vehicle to transform between land and water configurations without requiring a completely complex amphibious structure.
Solution Approach 2:
The vehicle employs dynamic reconfigurability where the chassis assembly can be detached from and reattached to different buoyant assemblies. This dynamic transformation allows the same base structure to adapt its function and environment compatibility without permanent modification.
2Adaptability or versatility
If a vehicle is designed with fixed propulsion mechanism, then it achieves efficient propulsion for its intended use, but it cannot transition between water and land
Solution Approach 1:
The propulsion system is designed with universal applicability across both land and water environments. The pedaling mechanism and transmission system remain consistent whether the vehicle is on wheels or floating elements, allowing users to operate the vehicle in either environment without learning different propulsion techniques.
3Use of energy by moving object
If a vehicle uses motorized propulsion, then it achieves high speed and efficiency, but it fails to provide physical exercise and has environmental impact
Solution Approach 1:
The vehicle employs human-powered propulsion where the users themselves provide the energy needed to move the vehicle. The pedaling and rowing mechanisms convert human physical effort directly into vehicle motion, eliminating the need for external fuel sources and providing health benefits while being environmentally friendly.

AI summary
The present invention provides a novel multiple-seat wagon propelled by simultaneously rowing and pedaling for use in water or land. The present invention provides a unique and versatile multiple-seat wagon that can be converted into a sea vessel. It allows the vehicle to float on water and serves as the lower part of the vessel. The water propulsion assembly includes two water wheels that are responsible for generating forward and backward motion when the vehicle is in water. It also has a water shaft that holds the water wheels. The pinion gear increases the rotational speed of the water wheels, enhancing the efficiency of propulsion from a pedaling motion and a rowing motion. The invention features a demountable coupling system that allows for disassembly and reassembly while maintaining the interconnection of its components.
