Unstable User Support Platform for Core Muscle Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise machines primarily focus on specific muscle groups, failing to effectively engage core muscles during exercises, leading to limited overall muscle engagement and balance challenges.
Innovation Solution
An exercise machine design featuring a stationary main frame with an unstable user support assembly that includes a pivotally mounted user support platform, allowing free rotation about non-vertical tilting axes, and a connecting linkage that links movement of the exercise arm assembly to the user support assembly, requiring users to engage their core muscles for balance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a stationary user support is used in conventional exercise machines, then the machine structure is simple and stable, but core muscles are not effectively engaged
Solution Approach 1:
The user support platform is transformed from a stationary structure to a dynamic one by introducing pivotal mounting that allows rotation about non-vertical tilting axes. This enables the platform to tilt and rock during exercise, requiring core muscle engagement while maintaining structural stability through controlled degrees of freedom.
Solution Approach 2:
The stability parameter of the user support is modified by changing its mounting configuration from fixed to pivotal. The platform's ability to rotate about tilting axes creates controlled instability that engages core muscles, while stop assemblies limit the rotation range to maintain overall system stability.
2Adaptability or versatility
If an unstable user support platform is introduced to engage core muscles, then core muscle engagement is improved, but the device complexity increases
Solution Approach 1:
The user support assembly is segmented into distinct functional components: the base mounted on the main frame, the pivotal connection mechanism, the user support platform, and stop assemblies. This segmentation allows each component to perform its specific function while simplifying the overall design and maintenance of the complex system.
Solution Approach 2:
The pivotal connection acts as an intermediary mechanism between the stationary base and the movable user support platform. It enables controlled rotation and tilting motion while maintaining structural integrity, bridging the gap between stability and instability requirements.
3Adaptability or versatility
If the user support platform is allowed free rotation about tilting axes, then core muscle engagement is enhanced, but control over rotation range is reduced
Solution Approach 1:
Stop assemblies are pre-positioned to limit the rotation range of the user support platform about its tilting axes. These stops act as mechanical constraints that prevent excessive rotation while allowing sufficient mobility for core muscle engagement within a safe and controlled range of motion.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances core muscle engagement by introducing instability, requiring users to balance the support platform during exercises, thereby improving overall muscle activation and balance, and can be adapted for various exercise positions and machines.
Implementation Method 1
a pivot connection between the user support platform and the base, configured for allowing free rotation of the user support platform about at least one non-vertical tilting pivot axis in at least two opposite directions between a centered user support position and first and second tilted end positions
Implementation Method 2
a stop assembly between the base and the user support platform which defines the respective first and second end positions and limits tilting movement from said centered support position in each direction to a predetermined angular range
Implementation Method 3
a connecting linkage between the user support assembly and the exercise arm assembly which links movement of the exercise arm assembly during an exercise to movement of the user support assembly about said first pivot axis
Implementation Method 4
a load which resists movement of at least one of the user support assembly, the exercise arm assembly and the connecting linkage

AI summary
An unstable user support device designed for mounting on an exercise machine has a base or mounting bracket and a user support platform configured for engagement by the user and pivotally mounted on the base for pivotal movement through a limited angle about a pivot axis extending in a plane parallel to the user support platform, The pivoting movement may be a side to side tilting movement. Stops between the base and support platform control the amount of pivoting movement. This arrangement provides a degree of instability to the platform, to provide a greater challenge to the user's core muscles in balancing the platform while performing an exercise motion.
