Neck-hanging Massager Elastic Arm Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neck massaging devices have a rigid structure that fails to conform to the neck's dimensions, leading to poor attachment of the electrode assembly, discomfort due to high elastic force, and skin or hair entrapment issues.
Innovation Solution
A neck-hanging massaging device with an elastic arm, adjustable handles, and an electrode assembly made of silicone rubber, allowing deformation to fit the neck's shape, reducing acmesthesia and preventing skin or hair entrapment, while balancing weight for comfortable attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main body is designed with a rigid and anti-deformation structure to protect the electric pulse generating device, then the device structure is stable, but the massaging device cannot be matched with the neck in dimension, causing poor attachment of the electrode assembly
Solution Approach 1:
The device is divided into a rigid main body (containing the electric pulse generating device) and a flexible elastic arm. This segmentation allows the main body to remain protected and stable while the elastic arm adapts to the neck's contours, resolving the contradiction between structural protection and dimensional adaptability.
Solution Approach 2:
The elastic arm is constructed from elastic materials that can deform to match the neck's shape, while the main body retains a rigid protective structure. This flexible component allows the device to conform to different neck dimensions without compromising the protection of the electric pulse generating device.
2Force
If springs with high elastic force are used to provide clamping force, then the massaging device can maintain contact with the neck, but consumers feel uncomfortable after long-term wearing, especially at the carotid artery
Solution Approach 1:
The patent changes the material parameter of the elastic arm from high-elastic-force springs to elastic materials with lower elastic force. This parameter change maintains sufficient contact force with the neck while reducing the harmful effect of excessive elasticity that causes discomfort at the carotid artery during long-term wear.
3Reliability
If the main body is made rigid to protect internal components, then the structure is stable, but the skin or hair of a user is often caught by the joints between the handles and the main body
Solution Approach 1:
The elastic arm is made from flexible elastic materials that can deform and move smoothly against the neck, eliminating sharp joints where skin or hair could be caught. The flexibility of the elastic arm maintains structural stability while preventing the entrapment issue that occurs with rigid joints.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device comfortably adapts to the neck's size, avoids acmesthesia, and reduces discomfort by using elastic deformation instead of high elastic force, ensuring stable and soft massaging.
