Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Swimmers face challenges in developing efficient swimming techniques due to limited proprioception and the inability to accurately perceive the spatial orientation of their body parts while in the water, leading to inefficiencies and increased risk of injury.
Innovation Solution
A swim paddle equipped with a low-profile housing, electronics package including a haptic feedback generator, orientation sensor, battery, and hardware processor that provides real-time sensory feedback to the swimmer based on the orientation of their hands and arms, helping them maintain optimal positioning and technique.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional swimming training methods are used, then swimmers can practice basic strokes, but they cannot accurately perceive the spatial orientation of their body parts leading to technique inefficiency and increased injury risk
Solution Approach 1:
The patent applies feedback by providing real-time haptic and visual signals to swimmers about their hand and arm orientation during swimming strokes. Orientation sensors detect the actual spatial position of the paddle, and this information is immediately communicated back to the swimmer through vibration patterns and LED indicators, enabling continuous adjustment and improvement of technique without requiring the swimmer to visually observe their own movements.
Solution Approach 2:
The patent replaces the natural but insufficient proprioceptive feedback system with an electronic sensing and feedback system. Instead of relying on the swimmer's innate sense of body position, which is inadequate in water, the system uses orientation sensors, microcontrollers, and haptic actuators to provide precise mechanical feedback about hand orientation, substituting the flawed biological sensing mechanism with a reliable electronic one.
2Productivity
If swimmers focus on breathing, lap counting, and other tasks, then they can complete swimming workouts, but they cannot focus on body position and orientation
Solution Approach 1:
The system allows swimmers to simultaneously attend to multiple tasks (breathing, lap counting) while the device autonomously monitors and provides feedback on body position. The automated feedback reduces the cognitive load required for technique monitoring, enabling swimmers to maintain proper form without consciously focusing on every aspect of their technique throughout the entire workout.
3Ease of operation
If the head position is adjusted for proper breathing, then swimmers can maintain airflow, but the orientation of hands and limbs becomes difficult or impossible to observe
Solution Approach 1:
The patent replaces visual observation with electronic sensing and haptic feedback. Since visual feedback is blocked by head position requirements for breathing, the system uses orientation sensors to detect hand and arm position and communicates this information through tactile vibration patterns and audible signals, substituting the blocked visual channel with alternative sensory pathways that remain accessible during proper breathing technique.

AI summary
A swim paddle can include a low profile housing body including a hand surface and a water surface. The low profile housing body can further include a longitudinal axis that is parallel to the length of a hand of a swimmer and a transverse axis that is parallel to a width of the hand, wherein the longitudinal axis is longer than the transverse axis, and wherein the hand surface is adjacent to a palm of the hand. The paddle can further include a strap that can secure the low profile housing body with the hand of the swimmer. The swim paddle can further include an electronics package that can be affixed to the low profile housing body.
