Laundry treatment apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses experience vibration issues during washing and drying processes, leading to potential ejection of the drawer from the cabinet, which affects durability and operational stability.
Innovation Solution
A laundry treatment apparatus with a drawer holder system that includes a fastening body, panel through hole, receiving body, and board supporter to securely lock the drawer panel to the cabinet, minimizing vibration and preventing ejection, while enhancing durability through strategic design features like cut portions and reinforcing portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drawer is designed to be ejectable from the cabinet for laundry treatment, then ease of operation is improved, but vibration occurs during rotation causing the drawer to be ejected from the cabinet
Solution Approach 1:
The drawer holder is divided into multiple functional components: a fastening body that protrudes from the cabinet, a receiving body that receives the fastening body, and a board supporter that supports the drawer panel. This segmentation allows each component to perform its specific function in reducing vibration while maintaining the overall ejection capability.
Solution Approach 2:
The drawer holder acts as an intermediary mechanism between the cabinet and the drawer panel. It provides a fastening connection that reduces vibration during drum rotation while still allowing the drawer to be ejected when needed, thus mediating between the conflicting requirements of stability and operability.
2Reliability
If the drawer panel is secured to the cabinet to minimize vibration, then durability is improved, but the drawer cannot be easily ejected for laundry treatment
Solution Approach 1:
The drawer holder provides a dynamic connection that adapts to different operational states. During drum rotation, the fastening body and receiving body engage to minimize vibration. During ejection operations, the connection can be disengaged to allow drawer movement. This dynamic behavior resolves the contradiction between stability and operability.
3Device complexity
If a simple drawer structure is used, then device complexity is reduced, but vibration causes the drawer to be ejected from the cabinet
Solution Approach 1:
Instead of making the entire drawer structure complex, the invention applies a localized drawer holder mechanism at specific positions where vibration occurs. The fastening body, receiving body, and board supporter are positioned to provide targeted vibration reduction without requiring complex structures throughout the entire drawer assembly.
4Strength
If the drawer holder uses rigid fastening components, then strength is improved, but the drawer panel cannot accommodate vibration movements
Solution Approach 1:
The drawer holder employs a composite structure combining rigid fastening components (fastening body and receiving body for strong connection) with a flexible board supporter that can accommodate vibration movements. This composite approach provides both strength and flexibility, resolving the contradiction between rigid fastening and vibration accommodation.
