Exercise Assist Tool Body-Axis Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abdominal and lumbar muscles training tools do not effectively suppress movement of the body axis during exercise, which can reduce the effectiveness of muscle strengthening and posture correction.
Innovation Solution
An exercise assist tool with a body-axis indicator that includes a proximal-side indicator and a distal-side indicator, supported to align along the craniocaudal axis, helping users maintain awareness of their body axis during exercises in a supine or seated state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional abdominal and lumbar muscles training tools are used, then muscle strengthening and posture correction can be achieved, but the body axis movement is not suppressed, reducing exercise effectiveness
Solution Approach 1:
A body axis indicator is introduced as an intermediary tool between the user and the exercise tool. The indicator visually displays the body axis position and movement, mediating the user's awareness and control during exercise to suppress unwanted body axis movement while maintaining exercise effectiveness
Solution Approach 2:
The body axis indicator provides real-time visual feedback to the user about their body axis position and movement during exercise. This feedback mechanism enables the user to adjust their posture and exercise form to suppress body axis movement, thereby improving exercise effectiveness
2Reliability
If the body axis movement is suppressed during exercise, then exercise effectiveness is maximized, but the device complexity increases due to additional indicators and support structures
Solution Approach 1:
The body axis indicator is segmented into multiple components: a support portion, a rod member, and indicators at specific positions. This segmentation allows each component to perform its specific function while keeping the overall structure relatively simple and easy to manufacture
Solution Approach 2:
The body axis indicator serves multiple functions: it visually indicates the body axis position, provides feedback on body axis movement, and guides proper exercise form. This multi-functionality reduces the need for additional separate devices, thereby limiting the increase in device complexity

AI summary
An exercise assist tool is used together with an exercise tool used in a supine or seated state, and the exercise assist tool includes a body-axis indicator that allows a user to be conscious of a body axis. The body-axis indicator has a longitudinal direction, and is supported such that the longitudinal direction can be disposed along a craniocaudal axis of the user. The body-axis indicator is a rod member supported so as to be disposed along a craniocaudal axis of the user. The body-axis indicator includes a proximal-side indicator provided in front of a face of the user, and a distal-side indicator provided farther from the user than the proximal-side indicator. The proximal-side indicator is configured to be capable of adjusting a distance from the user.
