Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resistance band systems for dumbbell workouts lack accurate measurement of load and repetitions, as they are dependent on the changing characteristics of the resistance band, leading to inconsistent and unreliable measurements.
Innovation Solution
A hand-held physique training device with ring-shaped force measurement sensors, distribution gaskets, and compression rings at both ends of a tubular handle, evenly distributing force applied by resistance bands to ensure precise and repeatable load and repetition measurements, connected to computing means for data processing and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor is attached to the resistance band to measure load, then measurement capability is provided, but the solution becomes dependent on specific resistance band characteristics and elongation, leading to inconsistent measurements over time
Solution Approach 1:
The patent introduces a force measurement sensor integrated into the handle structure as an intermediary element that directly measures the force applied to the handle, bypassing the need to measure resistance band elongation. This mediator approach allows accurate force measurement independent of resistance band characteristics, resolving the contradiction between providing measurement capability and ensuring consistent measurements over time.
Solution Approach 2:
The patent replaces the mechanical measurement approach (measuring resistance band elongation) with a direct force sensing system using load cells or force sensors integrated into the handle. This substitution eliminates the dependency on resistance band elastic properties and elongation measurements, providing reliable and consistent force measurements regardless of resistance band characteristics or age.
2Duration of action of stationary object
If resistance band characteristics change over time, then the resistance band continues to be usable, but the measured load values become inaccurate and inconsistent
Solution Approach 1:
The force measurement sensor in the handle acts as an intermediary that directly measures the force applied, independent of resistance band characteristics. This allows the resistance band to continue being used even as its elastic properties change over time, while maintaining accurate load measurements through direct force sensing rather than indirect elongation measurement.
3Loss of information
If a clamp and potentiometer system is used to measure resistance band elongation, then measurement capability is provided, but the solution cannot measure actual load and provides inconsistent results
Solution Approach 1:
The patent replaces the clamp-potentiometer elongation measurement system with a direct force measurement system using load cells or force sensors. This substitution enables accurate load measurement by directly sensing the force applied to the handle, rather than indirectly calculating load from elongation measurements, thereby providing both data capture and measurement precision.
4Ease of operation
If resistance bands are made lightweight and portable, then convenience and accessibility are improved, but the ability to provide sufficient resistance and variety is limited
Solution Approach 1:
The patent integrates a dynamic force measurement system into the portable handle that can accurately measure varying forces applied during different exercises. The computing means processes these dynamic force measurements to provide real-time feedback on load and repetitions, enabling users to perform diverse exercises with sufficient resistance tracking while maintaining portability and ease of operation.
Solution Approach 2:
The force measurement system and computing means in the handle provide multi-functional capability, enabling the measurement of load, repetition counting, and exercise form feedback across various resistance band exercises. This universal measurement approach allows a single portable device to support multiple exercise types with different resistance requirements, enhancing both exercise variety and portability.
