Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rowing machines do not effectively replicate the dimensions, appearance, and motion of Olympic-class rowing shells on land, nor can they connect resistance mechanisms between machines, limiting the realism and efficiency of training.
Innovation Solution
A rowing machine design that mimics Olympic-class rowing shells in dimensions and motion, allowing for adjustable 'rigging' and connectivity of resistance mechanisms between machines, enabling synchronized training and measurement translation between on-land and on-water environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rowing machines are designed to replicate Olympic-class rowing shells in dimensions and appearance, then the realism of training is improved, but the space requirements and device complexity increase
Solution Approach 1:
The rowing machine is divided into separate functional modules: a shell structure that replicates the Olympic-class rowing shell, a resistance mechanism, and a measurement system. This segmentation allows each component to be optimized independently while maintaining overall realism without excessive complexity.
Solution Approach 2:
The patent creates a simplified copy of the Olympic-class rowing shell environment rather than an exact replica. The shell structure, oars, and internal dimensions are replicated to provide authentic training feel while using lighter materials and reduced complexity compared to actual water rowing.
2Adaptability or versatility
If resistance mechanisms are made independent in each rowing machine, then device complexity is reduced, but the ability to simulate team rowing and synchronized training is limited
Solution Approach 1:
Multiple rowing machines are connected through a shared resistance mechanism system where the flywheel and damping mechanism are common to all machines in the team configuration. This merging allows synchronized resistance across all machines while maintaining a unified rather than multiplied complexity structure.
Solution Approach 2:
The resistance mechanism is designed to serve multiple functions: providing individual resistance to each rower while also enabling synchronized team training. The same flywheel and damping system can operate independently for single-machine training or connect multiple machines for team simulations.
3Adaptability or versatility
If measurement systems are machine-specific, then manufacturing precision and calibration are simplified, but the ability to translate measurements between on-land and on-water environments is limited
Solution Approach 1:
The measurement system uses universal sensors and measurement protocols that can operate both on-land during machine training and on-water during actual rowing. The same measurement parameters (stroke rate, power output, distance) are collected in both environments, enabling direct translation and comparison of performance data.
Solution Approach 2:
The system incorporates feedback mechanisms that continuously monitor and compare measurements from both on-land and on-water environments. This feedback loop allows the system to automatically translate and normalize measurements between the two contexts, improving adaptability while maintaining measurement consistency.
4Strength
If rowing machines use heavy steel construction to simulate Olympic shells, then structural strength and realism are improved, but the weight and space efficiency decrease
Solution Approach 1:
The shell structure uses composite materials that combine the strength needed to replicate the Olympic-class rowing shell with reduced weight. The shell is constructed to provide authentic structural characteristics and feel while using lighter materials compared to traditional steel construction, improving space efficiency.
