Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional manual lymphatic drainage treatment is used, then the treatment can be performed with simple equipment, but the pressure application and treatment duration lack control and reproducibility

Engineering Contradiction:
Improvecontrol and reproducibility of treatment parametersVSAvoidstructure of treatment device
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The rod is designed to be retractable relative to the handle, allowing dynamic adjustment of roller position and treatment parameters. The rod can move between extended and retracted positions, enabling operators to control treatment depth and pressure dynamically while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Signal means are incorporated to provide feedback on treatment parameters such as pressure applied and treatment duration. This feedback mechanism enables controlled and reproducible treatment by allowing operators to monitor and regulate key parameters, resolving the contradiction between reliability and device complexity.

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If pressure regulation mechanisms are added to control treatment parameters, then treatment efficacy is maximized, but device complexity increases

Engineering Contradiction:
Improvepressure control precisionVSAvoidmechanism structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The retractable rod mechanism provides dynamic pressure control without complex regulation systems. By adjusting the rod extension, operators can control the roller's contact pressure and treatment depth, achieving precise pressure control through simple mechanical movement rather than complex regulation mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Treatment parameters such as pressure and duration are controlled by changing physical parameters of the device operation - specifically the rod position and treatment time. This approach achieves precise parameter control through straightforward mechanical adjustments rather than complex control systems.

Inventive Principle:
Principle #35Parameter changes

AI summary

A roller device for lymphatic drainage treatments comprising a handle (2), a rod (4) having one end connected to the handle (2) and a roller (6) rotatably mounted at the other end of the rod, characterized in that the rod (4) is retractably mounted with respect to the handle, being movable between an extended position and a retracted position against the action of elastic means (14) for maintaining the rod in the extended position, in such a manner that a pressure increase exerted on the roller causes the retraction of the rod. The device preferably comprises signal means which supply a signal indicative of the level of pressure exerted on the roller, and preferably enable its display.
