Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing abdominal exercise devices are used, then the basic exercise function is provided, but variable resistance and effective feedback mechanisms are lacking
Solution Approach 1:
The patent applies the Dynamics principle by implementing a variable resistance mechanism that allows the resistance level to be adjusted during exercise. The spring-loaded resistance member can be compressed to different degrees, dynamically changing the resistance force applied to the rotating apparatus, thereby providing adaptability for different user needs and exercise intensities.
Solution Approach 2:
The patent applies the Universality principle by designing a multi-functional device that combines exercise functionality with resistance adjustment and feedback mechanisms. The central assembly integrates the rotating apparatus, resistance mechanism, and feedback system into a single unified device, allowing one device to serve multiple purposes: exercise, resistance control, and performance monitoring.
2Loss of information
If existing abdominal exercise devices are used, then the exercise function is provided, but real-time feedback and performance monitoring are insufficient
Solution Approach 1:
The patent applies the Feedback principle by incorporating sensors that detect the rotation of the rotating apparatus and provide real-time information about user performance. The feedback mechanism communicates resistance levels and exercise metrics to the user, enabling them to monitor their performance and adjust their exercise intensity accordingly, thus reducing information loss about exercise effectiveness.
3Adaptability or versatility
If a variable resistance mechanism is added to the exercise device, then resistance adjustability is improved, but the device complexity increases
Solution Approach 1:
The patent applies the Intermediary principle by using a spring-loaded resistance member that acts as an intermediary between the user's exercise motion and the resistance force. The spring mechanism translates rotational motion into controlled resistance force, providing smooth and adjustable resistance without requiring complex mechanical systems, thus managing device complexity while maintaining adaptability.
4Loss of information
If a sensor and controller system is implemented, then real-time feedback is improved, but the device complexity increases
Solution Approach 1:
The patent applies the Self-service principle by designing a control system that automatically monitors and provides feedback based on the exercise performance. The sensor and controller system operates autonomously to detect rotation, calculate resistance levels, and provide feedback without requiring manual intervention or complex external control mechanisms, thus reducing the overall system complexity while maintaining effective performance monitoring.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides adjustable resistance levels and real-time feedback, enhancing the effectiveness and monitoring of abdominal exercises, allowing users to track their performance and adjust the workout intensity accordingly.
Implementation Method 1
a spring positioned on a proximal side of the hub and operable to exert an axial force on the hub
Implementation Method 2
a brake plate interfacing surface configured to interface with the brake plate and have a frictional force exerted thereon by the brake plate, resisting the rotation of the rotating apparatus
Implementation Method 3
a sensor positioned on a distal side of the central assembly and a measuring member configured to interface with a structure on the proximal side of the central assembly... The sensor may be a pressure sensor comprising a pressure sensing surface and be configured to transmit a signal to the controller responsive to a measured pressure on the pressure sensing surface
Implementation Method 4
The proximal end of the axial member may comprise threads configured to engage with the threads of the threaded aperture. Manipulation of the body member by the user causes the threaded aperture to rotate with respect to the axial member, causing axial movement of the body member along the center axis

AI summary
An exercise device includes an axial member, a rotating apparatus, a variable resistance apparatus, and two handle assemblies. The axial member defines a center axis of a central assembly of the exercise device. The rotating apparatus is configured to rotate about the center axis and includes a surface interfacing member, a hub positioned around the axial member, and a plurality of spokes. The variable resistance apparatus includes a resistance member that exerts resistance to the rotation of the rotating apparatus, and a user control device operable to change a magnitude of resistance exerted by the variable resistance member. The two handle assemblies are positioned on opposite sides of the hub.
