Refrigerator having drawer
Solution Overview
Problem
The existing refrigerator drawer designs require complex and time-consuming assembly and disassembly processes, often resulting in damage to other parts due to the lack of a separate protection member at the edge of the metal side plate, which reduces work efficiency and increases the need for multiple people for assembly and disassembly.
Innovation Solution
The design incorporates a sliding mechanism for the outside cover to be easily attached and detached from the storage body, featuring a locking end that crosses into a fixing end, with a scratch prevention member at the edge to prevent damage during assembly and disassembly, eliminating the need for separate fixing components like screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the side plate is fixed to the side drawer supporting frame by welding or screw fastening, then the assembly is strong and stable, but the disassembly process is complex and time-consuming
Solution Approach 1:
The side plate is divided into a metal side plate and a separate protection member, allowing the protection member to be detached independently while the metal side plate remains securely fastened to the supporting frame. This segmentation enables easy removal of the protection member without affecting the structural integrity or requiring disassembly of the main assembly.
Solution Approach 2:
A separate protection member is introduced as an intermediary component between the metal side plate and the environment. This protection member can be easily attached and detached, providing protective functions without requiring complex fastening mechanisms for the main structural components.
2Strength
If the side plate is fixed by welding or screw fastening, then the connection is secure, but other parts may be damaged during assembly and disassembly
Solution Approach 1:
The protection member serves as an intermediary that absorbs the harmful effects during assembly and disassembly operations. It protects the metal side plate and supporting frame from scratching and chipping by providing a buffer during handling, while the secure fastening of the metal side plate remains intact.
Solution Approach 2:
The protection member is attached beforehand to the metal side plate to provide protective cushioning during assembly and disassembly processes. This pre-protection prevents scratching and chipping of the metal side plate and other parts before any damage can occur.
3Device complexity
If a separate protection member is not provided at the edge of the metal side plate, then the structure is simpler, but scratching and chipping occur during assembly and disassembly
Solution Approach 1:
A separate protection member is introduced as a simple intermediary component at the edge of the metal side plate. This addition provides minimal structural complexity while effectively preventing scratching and chipping during assembly and disassembly operations.
Solution Approach 2:
The protection member is applied locally only at the edge portions of the metal side plate where scratching and chipping are most likely to occur. This localized protection adds minimal complexity while providing targeted protection exactly where needed.
4Strength
If the assembly and disassembly processes are complicated, then the connection is secure, but work efficiency is reduced and more people are required
Solution Approach 1:
The assembly is segmented into the metal side plate (securely fastened) and the protection member (easily attached/detached). This segmentation allows one component to provide secure connection while another component enables quick assembly and disassembly, thereby improving work efficiency without compromising connection security.
Solution Approach 2:
The protection member is designed to be easily attached and detached by the user without requiring specialized tools or complex procedures. This self-service capability improves work efficiency by allowing single-person operation and reducing the time and effort required for assembly and disassembly tasks.
