Massage Backrest With Two-Layer Structure and Side Air Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage apparatuses with warm-cool air supply functions are too thick, making them uncomfortable for users when mounted on thin chairs, and they struggle to house both the massage mechanism and warm-cool air supply section due to insufficient space.
Innovation Solution
A massage apparatus with a backrest featuring a two-layer structure, where the massage mechanism can move up and down, and the warm-cool air supply section is located outside the massage mechanism's movement area, allowing both components to be housed within a thinner backrest and seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the backrest thickness is increased to house both the massage mechanism and warm-cool air supply section, then the space for accommodating components is improved, but the comfort of the user sitting on the chair deteriorates
Solution Approach 1:
The patent transitions from arranging components only in the front-rear direction (thickness direction) to utilizing the widthwise direction as well. The warm-cool air supply section is positioned in the widthwise direction at the both ends of the backrest, while the massage mechanism is positioned in the central region, enabling both components to coexist without increasing backrest thickness.
2Ease of operation
If the backrest thickness is reduced for mounting on thin chairs, then the user sitting comfort is improved, but the space for housing both massage mechanism and warm-cool air supply section deteriorates
Solution Approach 1:
The patent redistributes components across different spatial dimensions within the backrest. The massage mechanism occupies the central region extending in the lengthwise direction, while the warm-cool air supply section is placed at the widthwise ends, allowing both to fit within a thin backrest structure.
Solution Approach 2:
The backrest is functionally segmented into distinct regions: a central region for the massage mechanism and widthwise end regions for the warm-cool air supply section. This spatial segmentation allows independent optimization of each component's position without interference.
3Device complexity
If the warm-cool air supply section is positioned at the rear of the backrest, then the space arrangement is simplified, but the massage mechanism movement area is restricted
Solution Approach 1:
The warm-cool air supply section is repositioned from the rear (depth direction) to the widthwise ends of the backrest. This dimensional relocation allows the massage mechanism to move freely in the central region along the lengthwise direction without spatial conflict with the air supply components.
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
Enables the reduction of backrest and seat thickness in the front-rear direction while maintaining the functionality of the massage mechanism and warm-cool air supply, providing a comfortable and efficient massage experience.
Implementation Method 1
warm air or cool air fed into a space created between the front cover body and the back cover body... user's back can be warmed up and cooled down by exploiting warm air and cool air that have passed through the front cover body
Implementation Method 2
the front cover body has permeability to air, and therefore, warm air and cool air accumulated in the space between the front cover body and the back cover body are fed, through the air-permeable front cover body, to user's back side

AI summary
A massage apparatus in which both a massage mechanism and a warm-cool air supply section are housed inside a backrest. The massage apparatus includes a backrest for supporting a user's back; and a massage mechanism disposed inside the backrest for producing massage action on user's back. The backrest has a front side with a two-layer structure. A warm-cool air supply section is provided that is capable of feeding warm or cool air into an interlayer region of the two-layer structure. The massage mechanism can be moved up and down along the lengthwise direction of the backrest. The warm-cool air supply section is located outside of a movement area which is the range of up-and-down movement of the massage mechanism.
