Non-stretchable Ring Reinforcement for Fan Mounting in Airflow Mats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for forming fan-mounting parts in air-flow mats and A/C cloths are laborious and difficult to produce precisely, requiring skilled workers due to the need for folding and inserting non-stretchable materials, which can lead to inconsistencies and a higher likelihood of fans coming off due to stretching or shrinking.
Innovation Solution
A sheet with a fan-mounting part comprising a non-stretchable flat ring-shaped reinforcing section with an open shape matching the fan's cylinder part, where one face is fixed on the sheet's edge, allowing the fan to be mounted without folding or patching, providing a secure attachment and precise shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the non-stretchable material is inserted by folding the sheet member and patching fabric, then the fan-mounting part can be formed, but the production process becomes laborious and difficult to produce precisely
Solution Approach 1:
The non-stretchable flat ring-shaped reinforcing section is prepared in advance with the precise open shape matching the fan's cylinder part. This preliminary preparation eliminates the need for complex folding and patching operations during assembly, while ensuring precise shape formation from the start.
Solution Approach 2:
The reinforcing section is extracted as a separate component with the precise shape already formed. By taking out the shape-forming function into a dedicated pre-made component, the patent avoids the imprecision and labor involved in forming the shape through folding and patching operations.
2Reliability
If the fan-mounting part is formed by folding and inserting non-stretchable material, then the fan can be mounted, but the fan is more likely to come off due to stretching or shrinking
Solution Approach 1:
The non-stretchable flat ring-shaped reinforcing section is applied locally at the fan-mounting position to provide non-stretchable support. This localized reinforcement prevents stretching or shrinking specifically at the mounting area while maintaining the overall flexibility and comfort of the sheet member elsewhere.
Solution Approach 2:
The patent combines the stretchable sheet member material with the non-stretchable reinforcing section to create a composite structure. This composite design allows the sheet to maintain its inherent flexibility and comfort properties while the non-stretchable reinforcement provides stable, secure fan attachment without the fan coming off.
3Adaptability or versatility
If the same fabric as the A/C cloth is used for the fan-mounting part, then the outer appearance is consistent, but it is not economical for mass production
Solution Approach 1:
The patent segments the fan-mounting part as a separate component (the non-stretchable flat ring-shaped reinforcing section) that can be independently produced. This segmentation allows the reinforcing section to be manufactured separately from the main A/C cloth, enabling mass production of the reinforcement component while maintaining appearance consistency when attached to the cloth.
4Adaptability or versatility
If the fan-mounting part is formed in the sewing site, then the outer appearance is consistent, but it requires skilled workers and special equipment
Solution Approach 1:
The non-stretchable flat ring-shaped reinforcing section is prepared in advance as a ready-made component with the precise open shape. This preliminary action transfers the complexity of shape formation to the pre-production stage, allowing simple attachment operations at the sewing site that maintain appearance consistency without requiring skilled workers or special equipment.

AI summary
A sheet having a fan-mounting part for mounting a fan is provided. The fan includes a fan body including a cylinder part and a protrusion which is disposed on the cylinder part protruding in a direction substantially perpendicular to a side face of the cylinder part and an engaging member which is fitted on an outer side of the cylinder part and is thus attached to the fan body so as to be opposite the protrusion. The sheet having the fan-mounting part includes a sheet member and a non-stretchable flat ring-shaped reinforcing section. The sheet member has an open hole for receiving the cylinder part of the fan. The reinforcing section has an opening with substantially the same shape as an outer edge of the cylinder part of the fan.
