Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing physiotherapy devices lack a multifunctional design that combines vibration and balance training, and existing vibration systems are heavy and inconvenient due to magnetic shielding, limiting their usability and effectiveness.
Innovation Solution
A dual-purpose physiotherapy instrument with a movable board that can switch between balance and vibration modes using electromagnetic drives, incorporating electromagnets and permanent magnets for vibration and balance functions, with features like stoppers, protruding portions, and elastic cushions for safe and controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic shielding material is used in maglev vibration system, then vibration effect is improved, but device weight increases and becomes heavy and inconvenient to use
Solution Approach 1:
The patent removes the magnetic shielding material from the vibration system, extracting the harmful component while preserving the beneficial vibration function. The electromagnet system operates without requiring heavy shielding, significantly reducing device weight while maintaining vibration effectiveness for bone density improvement.
Solution Approach 2:
The patent converts the potentially harmful electromagnetic radiation into a beneficial therapeutic vibration by using the electromagnet to directly generate mechanical oscillations. The electromagnetic field itself becomes the source of therapeutic vibration rather than requiring separate shielding mechanisms, transforming a potential hazard into a therapeutic benefit.
2Reliability
If separate vibrators and balance boards are provided, then each function is specialized, but device complexity increases and cannot combine both functions
Solution Approach 1:
The patent merges the vibrator and balance board into a single integrated device. The movable board serves dual purposes: it can be positioned to provide vibration therapy through the electromagnet system, or positioned to create an unstable surface for balance training. This consolidation eliminates the need for multiple separate devices while maintaining both functional specializations.
Solution Approach 2:
The movable board is designed with universal functionality, capable of serving both as a vibration platform and as a balance training surface. By adjusting the board's position and the electromagnet activation, the same component delivers different therapeutic effects, making the device adaptable to multiple physiotherapy needs without increasing overall system complexity.
3Stability of the object's composition
If fixed board structure is used, then structural stability is improved, but cannot switch between balance and vibration modes
Solution Approach 1:
The patent transitions from a fixed board structure to a dynamic, movable board that can be repositioned along the device. This mobility allows the board to assume different configurations: stable positions for vibration therapy where the electromagnet can effectively couple with the board, and unstable positions for balance training where the board creates challenging surface conditions. The structural stability is maintained through controlled movement mechanisms while adaptability is achieved through reconfigurability.

Function Achieved in This Case
The instrument provides a safe and convenient means for users to switch between vibration and balance training, enhancing muscle and bone health through controlled vibrations and balance exercises, with improved usability and safety features.
Implementation Method 1
the movable board can integrally vibrate up and down under the action of the electromagnetic drives
Implementation Method 2
the electromagnets are mounted inside the accommodating cavity structure; the permanent magnets are arranged at the bottom of the plate body

AI summary
A dual-purpose physiotherapy instrument includes a base, electromagnetic drives, a plate body and a movable board. The plate body is mounted on the upper end of the base. A surface of the plate body away from the base includes stoppers. The movable board is mounted to the plate body in a detachable manner. A first surface on the movable board includes limit holes that are matched with the stoppers. The middle part of a second surface opposite to the first surface includes a protruding portion. When the first surface of the movable board is mounted to the plate body, the movable board can integrally vibrate up and down. When the second surface of the movable board is mounted to the plate body, the protruding portion is pressed against the plate body to cause the two ends of the movable board to swing up and down relative to the support portion.
