Solution Overview
Problem
Conventional lymphatic drainage treatments lack control and reproducibility in pressure application and treatment duration, making it difficult to maximize treatment effects and standardize the process.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering 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
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.
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.
2Manufacturing precision
If pressure regulation mechanisms are added to control treatment parameters, then treatment efficacy is maximized, but device complexity increases
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.
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.

Implementation Method 1
resilient means 14, associated with the handle, for maintaining the rod in the stable extended position; in this way, when a pressure increase is exerted on the roller 6, the rod 4 is caused to retract against the action of the resilient means 14

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.
