Laundry Dryer Carrier Above Drum Axis for Delicate Item Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry dryers often damage delicate items during the drying process due to drum rotation, and users face difficulty accessing the drum when using carriers that are mounted, especially under the carrier, which can also be damaged by items like shoes.
Innovation Solution
A carrier system with U-shaped protrusions that can be securely mounted to a connection member positioned above the drum's rotational axis, allowing easy access to the drum's entire space without rotating with it, and can be easily installed and removed, featuring a perforated structure for better air circulation and integrated design for reduced assembly errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a carrier is mounted to the frame in the laundry dryer, then delicate items are protected from damage during drum rotation, but user access to the drum becomes difficult especially under the carrier
Solution Approach 1:
The carrier is designed to be movable along the frame rather than fixed in one position. The connection members allow the carrier to slide horizontally and vertically, enabling users to move the carrier aside to access items under it while maintaining protection when in use
Solution Approach 2:
The carrier system is divided into separable components including the carrier body and connection members that attach to the frame. This segmentation allows the carrier to be detached or repositioned independently, facilitating user access while maintaining protective functionality when needed
2Strength
If a carrier is mounted to the lower portion of the frame, then heavy items can be supported, but the filter must be dismounted first which complicates the mounting process
Solution Approach 1:
The connection members are pre-installed on the frame during manufacturing, eliminating the need for users to dismount the filter or perform preliminary disassembly steps. The carrier can be directly attached to the pre-positioned connection members, simplifying the mounting process while maintaining support capacity
3Strength
If the carrier is made as a closed lattice structure, then structural strength is improved, but air circulation for drying is reduced
Solution Approach 1:
The carrier employs a wire mesh construction where the material distribution is optimized locally - sufficient wire thickness and spacing are provided to maintain structural strength while creating open areas that allow air circulation. Different regions of the carrier may have slightly different mesh densities to balance strength requirements with drying efficiency

AI summary
The present invention relates to a laundry dryer (1) comprising a drum (2) wherein the items to be dried are placed, a frame (4) located at the front side of the drum (2), having a loading port (3) that enables the laundry to be loaded into the drum (2) and to be unloaded therefrom, at least one connection member (5) that is located at the side of the frame (4) facing the drum (2) and a carrier (7) that is mounted to the connection member (5) to prevent the deformation of the items to be dried.
