Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rowers and coaches face challenges in remotely observing and analyzing rowing strokes to identify inadequacies and communicate modifications effectively, and existing imaging systems fail to provide comprehensive visual records of rowing actions.
Innovation Solution
A dual-lens imaging system with parallel axes, capable of simultaneous image capture from opposing directions, is mounted on a rowing apparatus to record the rower and oar's actions, providing synchronized and timestamped images for detailed analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single imaging device is used to capture rowing stroke, then the device complexity is low, but the measurement precision and completeness of rowing technique analysis is insufficient
Solution Approach 1:
The imaging system is segmented into multiple independent imaging devices, each capturing different views of the rowing stroke. The array of lenses captures images from multiple directions simultaneously, allowing comprehensive analysis of rowing technique without requiring a single complex device to perform all functions
Solution Approach 2:
The system transitions from single-view imaging to multi-dimensional imaging by positioning lenses at different locations and orientations. This captures spatial relationships and temporal sequences of rowing movements from multiple perspectives, enhancing measurement precision through dimensional expansion
2Measurement precision
If multiple imaging devices are positioned at different locations to capture comprehensive rowing views, then the measurement precision improves, but the device complexity and synchronization difficulty increases
Solution Approach 1:
Multiple imaging devices are merged into a single integrated array of lenses mounted on the rowing apparatus. This combining approach maintains the benefits of multi-perspective imaging while reducing system complexity through unified mounting and synchronized operation from a single structural platform
Solution Approach 2:
The imaging array is mounted directly on the rowing apparatus at the pivot point, allowing it to move with the oar and automatically maintain optimal positioning. This self-adjusting mechanism eliminates the need for complex external mounting and synchronization systems, as the apparatus itself provides the stable reference frame
3Measurement precision
If the imaging device is mounted away from the pivot point to capture overall rowing motion, then the field of view is wider, but the measurement precision of oar and rower coordination decreases
Solution Approach 1:
The imaging system focuses on capturing high-quality local details of oar-rower coordination at the pivot point rather than attempting to capture the entire rowing environment. By positioning lenses at the critical pivot point, the system prioritizes measurement precision of key coordination points over broad field of view coverage
