Air-Circulating Mat Battery Layout to Prevent Seat Shifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-circulating mats for seating devices face issues with shifting and falling due to the weight of the power supply device, leading to complex structures, increased costs, and reduced convenience.
Innovation Solution
The air-circulating mat features a bag-shaped body with a built-in battery container located on the back side of the user, which stabilizes the mat by distributing the weight to the seating surface, along with a spacer designed for low air resistance and flexibility, allowing for easy folding and use on various seating devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power supply device is mounted on the spacer extension portion close to the air blowing means, then the air blowing means can be powered, but the air-circulating mat shifts and falls due to the weight of the power supply device
Solution Approach 1:
The patent relocates the battery-containing power supply device from the horizontal plane (spacer extension portion) to the longitudinal dimension (back portion side of the user). This dimensional shift moves the weight distribution from a position that causes shifting to a position that enhances stability by anchoring the mat against the user's back.
Solution Approach 2:
Instead of mounting the power supply device at the front or center near the air blowing means, the patent inverts the conventional approach by placing it at the opposite end (back portion side). This inversion transforms the weight from a destabilizing factor into a stabilizing anchor that prevents the mat from sliding off the seating device.
2Ease of operation
If the power supply device is mounted on the spacer extension portion, then the air blowing means can be powered, but further means such as tying the air-circulating mat to the chair is needed, which makes the structure complicated and increases cost
Solution Approach 1:
The patent extracts the power supply device (battery) as a separate contained element within the mat structure, specifically in the back portion. This extraction allows the weight to be used beneficially for stability without requiring additional external fastening mechanisms, thereby simplifying the overall structure while maintaining ease of operation.
3Stability of the object's composition
If the battery is contained in the battery containing portion on the back side of the user, then the air-circulating mat does not shift and fall, but the weight distribution must be optimized
Solution Approach 1:
The patent applies local quality by concentrating the battery-containing portion specifically at the back portion side of the user, creating a localized weight distribution. This localized placement provides targeted stability at the rear of the mat, preventing shifting without requiring uniform weight distribution throughout the entire structure.
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
This design prevents shifting and falling, enhances stability and convenience, reduces power consumption, and lowers manufacturing costs by integrating the battery container and spacer through injection molding.
Implementation Method 1
air blowing means mounted on the opening portion and causing air to flow through the bag-shaped body by forcedly suctioning the air from an outside or by forcedly discharging it to the outside
Implementation Method 2
spacer for ensuring an air path through which the air flows inside the bag-shaped body

AI summary
An air-circulating mat for a seating device is disclosed. At a lower end part of a bag-shaped body, an opening portion for mounting an air blower is formed. A spacer ensures an air path through which the air flows inside the bag-shaped body and is contained in the bag-shaped body. This spacer is made of plastic and includes a plurality of convex parts and a plurality of flexible connection portions with flexibility for connecting the adjacent convex parts. At an upper end part on the right side of the bag-shaped body is an air circulating portion for discharging the air flowing through the air path to the outside. A battery containing portion for containing a battery that supplies electric power to the air blower is provided so as to continue to a predetermined end portion of the spacer located on a back portion side of a user in use.
