Massage Device Adjustable Handle With Spring-Biased Locks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage devices lack the ability to provide different massaging effects due to a solidly molded outer layer that cannot be adjusted relative to the inner housing, limiting the variety of massage operations.
Innovation Solution
A massage device with an adjustable structure featuring a handle device with spring-biased lock mechanisms, detachable hand grips, and interchangeable massage members, including wheels and rollers, allowing for quick configuration changes to accommodate various massaging operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the outer layer is solidly molded on the inner housing, then the structural integrity is improved, but the adaptability to provide different massaging effects deteriorates
Solution Approach 1:
The massage device is divided into separate components: an inner housing and an outer layer that can be detached. The outer layer includes a recessed portion that receives the inner housing, allowing the outer layer to be removed and replaced while maintaining structural integrity during assembly. This segmentation enables different outer layers with various massage characteristics to be used with the same inner housing.
Solution Approach 2:
The inner housing serves as a universal component that can work with multiple different outer layers. The standardized interface between the inner housing and outer layer allows the same inner housing to support various outer layers designed for different massaging effects, making the device multi-functional and adaptable to different user needs.
2Ease of manufacture
If the outer layer is solidly molded on the inner housing, then the manufacturing simplicity is improved, but the ease of adjustment and replacement deteriorates
Solution Approach 1:
By segmenting the device into separable components (inner housing and outer layer with recessed portion), the design maintains manufacturing simplicity through straightforward assembly while enabling easy adjustment and replacement of the outer layer when different massaging effects are needed, resolving the contradiction between manufacturing simplicity and ease of adjustment.
3Device complexity
If the massage device has a fixed configuration, then the device complexity is reduced, but the versatility for different massaging operations deteriorates
Solution Approach 1:
The device is segmented into modular components that can be easily assembled and disassembled, maintaining relatively simple device complexity while enabling versatility through the ability to replace outer layers with different massage characteristics. The standardized interface simplifies the modularity, preventing excessive complexity.
Solution Approach 2:
The design transitions from a fixed configuration to a dynamic, adjustable configuration where the outer layer can be detached and replaced. This dynamic capability allows the same device structure to adapt to different massaging operations while maintaining manageable complexity through the standardized connection interface.

AI summary
A massage device includes a handle device having two end portions, two hand grips attached to the end portions of the handle device, and two spring biased lock devices are engaged into the end portions of the handle device and each include a projection for engaging with the handle device and for extending out of the handle device and for preventing the hand grips from being disengaged from the handle device. An arm is attached to one of the end portions of the handle device, and includes a sleeve for engaging onto the handle device and for engaging with one of the spring biased lock devices. One or more massage members are detachably attached to the end portions of the arm.
