Stationary Massage Device Shear Force Generation via Segmented Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soft tissue strain release devices fail to generate sufficient shear forces for effective massage therapy, lacking the ability to sit still against body movement and distribute forces in a strip shape parallel to myofilaments, and are limited in their ability to fit various body locations and provide both stripping and probing actions with temperature control.
Innovation Solution
A stationary massage device with a bar-shaped body featuring multiple surfaces, edges, and corners, allowing for stable shear force generation, flexible orientation, and temperature control through heating or cooling, enabling both stripping and probing massage therapies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional ball or cylinder-shaped massage devices are used, then the device structure is simple, but the shear force generation capability is insufficient
Solution Approach 1:
The massage device is divided into multiple independent elements (protrusions, ridges, corners) arranged in specific patterns on the contact surface. Each element serves a specific function in generating shear forces, allowing the device to achieve complex massage effects through simple geometric segmentation rather than complex mechanical structures.
Solution Approach 2:
Different regions of the contact surface are designed with different geometric features (flat areas for general massage, protrusions for trigger points, ridges for linear stripping). This local differentiation allows each area to optimize its function for specific massage techniques, enhancing overall shear force generation capability.
2Adaptability or versatility
If the massage device is designed to fit various body locations, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The device incorporates multiple contact elements (flat surfaces, protrusions, ridges, corners) that can be used in various combinations and orientations to address different body parts and conditions. This multi-functional design allows a single device to perform multiple massage techniques (stripping, probing, general massage) without requiring multiple specialized tools.
Solution Approach 2:
The contact surface is designed with three-dimensional geometric features (protrusions extending from the surface, ridges creating linear elements, corners forming point contacts). These dimensional variations allow the device to create different contact geometries (point, line, area) from a single planar base, enhancing versatility without adding multiple separate components.
3Force
If the device remains stationary to generate shear forces, then the shear force effectiveness is improved, but the ease of operation decreases
Solution Approach 1:
Instead of moving the massage device along the body to generate shear forces, the device is designed to remain stationary while the user's body moves over it. This inversion of the traditional approach allows the device structure to stay simple and stable while still achieving effective shear force generation through the relative motion of the user's body against the fixed contact elements.

AI summary
A stationary massage device, system and corresponding methods are used for self-administrated or assisted soft tissue strain release (including trigger point therapy, strain-and-counterstrain therapy and neuromuscular release). The massage device comprises a body, wherein the body may include branches, each having flat surfaces, edges, ridges or corners. The surfaces, edges and ridges may be pushed along the myofilament direction of the soft tissues to produce pressing, rubbing, stretching and pulling actions on the soft tissues as stripping massages. The system can be configured to form different geometric shapes, and made of different materials of different firmness. The system can be further configured to perform unheated, or heated massages; and cooling treatments. In addition to being used alone, the system can be mounted on a piece of wall, a standing frame, furniture or a garment.
