Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vibration therapy equipment uses fixed rope lengths, then the equipment structure is simple, but the adaptability to different users and therapy needs is reduced
Solution Approach 1:
The patent implements adjustable rope lengths that can be dynamically modified during therapy sessions. The rope fastening system allows users to change rope lengths without leaving the equipment, enabling adaptation to different body sizes, therapy stages, and preferences while maintaining a relatively simple overall structure.
Solution Approach 2:
The rope system is divided into adjustable segments with multiple fastening points. This segmentation allows independent adjustment of rope length while keeping the overall equipment structure simple and modular, resolving the contradiction between adaptability and structural complexity.
2Adaptability or versatility
If vibration frequency is fixed, then the device is simple to operate, but the effectiveness for different musculoskeletal conditions is reduced
Solution Approach 1:
The vibration apparatus incorporates adjustable frequency controls that allow therapists to dynamically modify vibration parameters based on specific musculoskeletal conditions and user responses. This dynamic adjustability enhances effectiveness across different conditions while maintaining user-friendly operation through intuitive controls.
Solution Approach 2:
The system enables continuous adjustment of vibration frequency parameters to optimize therapy effectiveness for different musculoskeletal disorders. By allowing parameter changes without complicating the overall operation, the patent resolves the contradiction between adaptability and ease of operation.
3Adaptability or versatility
If vibration amplitude is fixed, then the device structure is simple, but the ability to target specific therapy needs is reduced
Solution Approach 1:
The vibration apparatus incorporates adjustable amplitude controls that enable dynamic modification of vibration intensity based on therapy objectives and user tolerance. This dynamic control allows precise targeting of specific therapy needs while maintaining a relatively simple overall device structure through straightforward control mechanisms.
Solution Approach 2:
The system provides localized control of vibration amplitude at different points along the rope, allowing therapists to target specific body regions and therapy needs. This local quality adjustment capability enhances therapy specificity without significantly increasing overall device complexity.
4Adaptability or versatility
If the vibration point is fixed along the rope, then the apparatus is simple, but the versatility for different body parts and therapy stages is reduced
Solution Approach 1:
The rope is divided into multiple segments with designated vibration application points. This segmentation allows the vibration apparatus to be positioned at different locations along the rope corresponding to different body parts and therapy stages, enhancing versatility without significantly increasing device complexity through modular design.
Solution Approach 2:
The system enables dynamic repositioning of the vibration application point along the rope during therapy sessions. This dynamic adaptability allows targeting of different body parts and therapy stages while maintaining a simple overall apparatus design through straightforward positioning mechanisms.

AI summary
A vibration apparatus (8) for use on therapy and exercise equipment of the type that has one adjustable, hanging rope or a pair of adjustable, hanging ropes (5; 6) to which is attached a grip portion, sling or other support member (3; 4) for an equipment user (1), the vibration apparatus being designed to be attached to the rope or to extend between the ropes and controllably set the rope or ropes in vibration. The vibration apparatus is freely, but fixably mountable at any level along the hanging length of the rope or ropes by means of rope gripping members (9; 10) on the apparatus or at respective ends of the apparatus, and the vibration apparatus has an actuator, for example, in the form of at least one electrically controllable motor (11; 12; 13) that cooperates with at least one weight (H'; 11"; 12'; 12"; 13'; 13") that is eccentrically supported in relation to the rotational axis of the motor.
