Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage devices with hot compress functions cause discomfort due to prolonged heat application, leading to a burning sensation and reduced user experience.
Innovation Solution
A shoulder and neck massager with movable massage mechanisms and a hot compress module that alternates between proximity and distance from the body, combined with a heat dissipation gap, to prevent continuous heat exposure and enhance comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If long-time hot compress is applied on the massage part, then the hot compress function is achieved, but the user experience deteriorates due to burning sensation
Solution Approach 1:
The patent implements periodic action by making the massage head move periodically between contacting and separating from the massage part. The control unit controls the driving mechanism to drive the massage head to move back and forth, creating periodic contact and separation cycles. This periodic motion allows the hot compress module to apply heat only during contact phases while dissipating heat during separation phases, preventing continuous heat exposure and burning sensation.
Solution Approach 2:
The patent applies dynamics by transforming the static massage head into a dynamically movable component. The driving mechanism (motor-driven transmission system) enables the massage head to dynamically adjust its position, moving between contact and separation states. This dynamic configuration allows the system to control heat application timing, applying heat only when needed during contact phases while allowing heat dissipation during separation phases.
2Productivity
If the massage head is kept close to the body, then continuous massage effect is achieved, but heat dissipation is reduced causing discomfort
Solution Approach 1:
The periodic motion of the massage head creates alternating phases of contact (for massage and hot compress) and separation (for heat dissipation). During contact phases, the massage head provides continuous massage effect and hot compress. During separation phases, the massage head moves away from the body, creating space for heat dissipation from both the hot compress module and the massage head itself, preventing heat accumulation and discomfort.
Solution Approach 2:
The air gap created during separation phases acts as an intermediary heat dissipation path. When the massage head separates from the body, air circulation between the massage head and the body surface facilitates heat dissipation. This intermediary space allows heat to escape without direct contact, maintaining comfort while preserving the effectiveness of contact phases.

AI summary
A shoulder and neck massager includes a main body, a circuit board, two first massage mechanisms, a driving mechanism and a hot compress module. The first massage mechanisms and the hot compress module are arranged on the skin-proximal side of the main body. The circuit board and the driving mechanism are arranged in the main body. The driving mechanism is connected to the first massage mechanisms. When the two first massage mechanisms are driven by the driving mechanism to move towards or away from each other along the first direction, the skin-proximal side moves away from or close to the human body. The hot compress module performs hot compress on the massage part when the skin-proximal side is close to the human body.
