Solution Overview
Problem
Dishwasher trays with elevating structures face challenges in ease of use, assembly, and disassembly, and are prone to malfunction due to bending under load, necessitating a design that enhances user convenience and stability.
Innovation Solution
The dishwasher incorporates a storage part with a guide, frame, and tray system, featuring a locking mechanism with a hook and rail configuration that allows for easy elevation and lowering of the tray, along with a link system for supporting horizontal and vertical movement, and a button mechanism for user-controlled horizontal movement, ensuring secure coupling and decoupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tray with elevating structure is provided for user convenience, then ease of operation is improved, but the tray is prone to malfunction due to bending under repeated load
Solution Approach 1:
The tray structure is divided into multiple segments including a tray body, elevating links, and coupling mechanisms. This segmentation allows each component to bear specific loads and reduces stress concentration, preventing bending and malfunction while maintaining ease of operation through modular elevation capability
Solution Approach 2:
The tray employs a dynamic elevating mechanism with links that can rotate and adjust positions based on load conditions. The links connect the tray body to the storage part frame, enabling controlled vertical movement that reduces impact forces and prevents structural bending during repeated elevation cycles
2Reliability
If the tray structure is made complex to suppress bending under load, then reliability is improved, but assembly and disassembly become difficult
Solution Approach 1:
The reliable tray structure is achieved through segmented modular components that can be easily assembled. The tray body, links, and coupling mechanisms are separate parts that connect through simple interfaces, maintaining reliability through proper load distribution while enabling easy assembly and disassembly
Solution Approach 2:
The tray components are designed with nested coupling mechanisms where links attach to the tray body and frame through interlocking structures. This nesting approach creates a stable, reliable assembly that resists bending while allowing straightforward assembly by simply engaging the nested components in sequence
3Ease of manufacture
If the tray is designed for easy assembly and disassembly, then ease of manufacture is improved, but the tray may separate under load
Solution Approach 1:
The coupling mechanism uses dynamic linkages that automatically engage and lock under load conditions. The links connect the tray body to the frame through rotating joints that maintain strong coupling during elevation while allowing easy assembly through simple engagement motions, preventing separation without requiring complex fastening
