Electric component mounting unit for air-conditioned garment, and air-conditioned garment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-conditioned garments face issues such as labor-intensive production due to the need for special attaching holes for fans, risk of electric components coming off, weight, and disturbances caused by air pressure, as well as vibration and noise from unbalanced fan blades.
Innovation Solution
An electric component mounting unit that includes a fan with a cylindrical linker and a mounter, where the fan is attached using a belt or band, allowing for secure attachment without special holes and reducing weight distribution, with features like elastic components and adjustable length to manage fan movement and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fans are attached to the garment body using special attaching holes, then the fans can be securely fixed, but additional labor is required in production and the garment becomes heavier
Solution Approach 1:
The fan attachment function is extracted from the garment body itself and transferred to a separate belt-like mounter. The mounter includes attaching portions that connect to the garment body, while the fan is mounted on the mounter rather than directly on the garment. This separation eliminates the need for special attaching holes in the garment body, reducing production complexity while maintaining secure fan attachment through the mounter's dedicated fixing structure.
2Power
If fans are attached to the garment body, then air cooling function is achieved, but the garment body becomes heavier and the attaching holes billow due to positive pressure
Solution Approach 1:
The system is segmented into three main components: the garment body, the belt-like mounter, and the fan assembly. The mounter acts as an intermediate carrier that holds the fan and connects to the garment body through fastening portions. This segmentation allows the fan weight to be distributed and supported by the mounter's belt structure rather than concentrating weight at attachment points on the garment body, reducing overall garment weight while maintaining air intake capability.
3Strength
If the fan structure is made robust to withstand impact, then the fans can resist external forces, but the motor bearing is deformed during press-fitting and noise is generated
Solution Approach 1:
The mounter is designed with shock-absorbing characteristics to provide beforehand cushioning for the fan assembly. When external impacts occur, the mounter's belt-like structure and flexible connections absorb and distribute the impact forces, preventing direct transmission to the motor bearing. This protects the motor from deformation and reduces noise generation while maintaining the fan's ability to withstand external forces.
4Shape
If the fan is suspended by the garment body, then the fan can be positioned on the body, but vibration from unbalanced fan blades affects motor lifetime and generates noise
Solution Approach 1:
The mounter serves as an intermediary between the fan and the garment body. It includes a fan holding portion that secures the fan assembly and connects to the garment body through attaching portions. This intermediary structure provides stable positioning while isolating the motor from direct vibrations caused by unbalanced fan blades, thereby extending motor lifetime and reducing noise while maintaining proper fan positioning on the body.

AI summary
An electric component mounting unit for an air-conditioned garment, which is used in combination with a garment body having a fan opening and which is mounted on a body, includes a fan which takes air from outside into the garment body, a mounter which mounts the fan on the body, and a fan attacher which attaches the fan to the mounter. The fan includes a fan-side linker which links the fan with the fan opening.
