Sloping Applicator Surface for Controlled Mechanical Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for applying impacts and pressure waves to the body surface are limited in their ability to provide controlled and comfortable treatment, especially when moved over the body surface, due to their flat front surfaces which require vertical positioning and lack of edge-free, sloping designs.
Innovation Solution
The device features a sloping front surface portion making up at least 30% of the applicator's surface area, angled between 30° and 60° relative to the impact direction, with edge-free and curved designs to enhance grip and control during movement, allowing for more effective massage and impact distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flat front surface is used on the applicator, then the device structure is simple, but the ease of operation deteriorates because vertical positioning is required and control during movement is difficult
Solution Approach 1:
The applicator front surface is designed with a curved, domed shape instead of a flat surface. This curvature allows the applicator to be positioned at various angles against the body surface while maintaining stable contact, eliminating the requirement for precise vertical positioning and enabling easier manual control during treatment.
Solution Approach 2:
The invention transitions from a two-dimensional flat surface to a three-dimensional curved surface. This dimensional change adds angular flexibility, allowing the applicator to conform to different body contours and be operated more easily without compromising structural complexity.
2Object-affected harmful factors
If an edge-free design with large radii of curvature is used, then the risk of irritation and injury to the patient is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The applicator incorporates continuously curved surfaces with large radii of curvature (R ≥ 2 mm) that eliminate sharp edges and corners. This design prevents skin irritation and injury while the curvature can be achieved through standard manufacturing processes such as molding or machining, balancing patient safety with manufacturing feasibility.
3Ease of operation
If a sloping front surface portion making up at least 30% of the front surface is used, then the ease of operation and control during movement is improved, but the device complexity increases
Solution Approach 1:
The sloping front surface is integrated into a domed, curved applicator geometry where the slope is a natural consequence of the curvature rather than an added feature. This approach improves operational control and comfort during manual movement while avoiding the need for complex multi-component structures.
4Productivity
If the applicator is designed for larger movements of the center of gravity, then the productivity is improved by allowing larger strokes, but the stability of the applicator position deteriorates
Solution Approach 1:
The curved, domed front surface of the applicator provides a stable contact geometry that maintains positional stability even during larger amplitude movements. The curvature distributes contact forces evenly, preventing unpredictable shifts in applicator position while allowing therapists to perform larger treatment strokes efficiently.
