Solution Overview
Problem
Existing methods for measuring maximum voluntary contraction (MVC) of isolated muscle groups are limited in range, require significant setup time, and pose a risk of injury, failing to provide comprehensive and efficient measurement and training solutions.
Innovation Solution
A portable and adjustable testing and training apparatus with an upright frame, instrumentation support, and rotatable force sensors that output data signals, allowing for measurement and training across multiple planes and muscle groups with quick setup and reduced risk of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing methods are used to measure MVC of isolated muscle groups, then measurement capability is provided, but the range of muscle groups that can be measured is very limited
Solution Approach 1:
The apparatus is designed with a universal frame structure that can accommodate multiple force sensors positioned at various locations and orientations, enabling measurement of MVC across diverse muscle groups including quadriceps, hamstrings, glutes, calves, and core muscles through a single integrated system
Solution Approach 2:
The system divides the measurement function into multiple independent force sensors that can be individually positioned and configured for specific muscle groups, allowing the apparatus to address the limited range problem by modularly expanding measurement capabilities
2Productivity
If existing MVC measurement methods are used, then measurement is provided, but significant setup time is required
Solution Approach 1:
The force sensors are pre-configured and pre-positioned on the frame structure during manufacturing, with quick-connect interfaces that allow rapid attachment and configuration for different muscle groups without requiring complex assembly procedures
Solution Approach 2:
The apparatus incorporates adjustable and reconfigurable components that can be quickly modified between measurements, allowing the system to adapt to different muscle groups and testing protocols without time-consuming reconfiguration
3Reliability
If existing MVC measurement methods are used, then measurement capability is provided, but risk of injury is presented
Solution Approach 1:
The apparatus incorporates real-time force measurement feedback through force sensors that monitor MVC measurements, providing immediate data on force production that can be used to ensure safe measurement levels and prevent injury during testing
Solution Approach 2:
The force sensors act as intermediaries between the user and the measurement system, providing indirect measurement of muscle force through controlled interaction with the apparatus, thereby reducing direct physical strain and injury risk
4Adaptability or versatility
If a portable and adjustable apparatus with rotatable force sensors is used, then measurement range and efficiency are improved, but device complexity increases
Solution Approach 1:
The frame structure is designed as a universal platform that integrates multiple functions including support for force sensors, adjustment mechanisms, and rotation capabilities within a single cohesive structure, reducing the need for multiple separate components
