Solution Overview
Problem
Existing refrigerator door designs with detachable panels face issues such as difficulty in removal due to adhesives, weakened support, complex assembly processes, and unintended detachment due to magnetic forces, especially with repetitive opening and closing.
Innovation Solution
A refrigerator door design featuring a frame assembly with upper and lower coupling mechanisms, including coupling protrusions and grooves, and a locking mechanism that allows easy panel replacement and secure attachment without space constraints, using a combination of adhesive and magnetic coupling for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If adhesive is used to attach the glass panel to the support part, then the panel is securely fixed, but the panel cannot be easily removed
Solution Approach 1:
The attachment mechanism is divided into multiple components: support parts with recessed parts on the frame, attachment parts on the glass panel, and fastening members that connect them. This segmentation allows the panel to be securely attached when assembled while enabling easy removal by detaching the fastening members, resolving the contradiction between stable fixation and ease of removal.
2Strength
If the support part and attachment part are fastened through a screw, then the connection is strong, but the assembly process becomes complicated
Solution Approach 1:
The fastening members are designed to be inserted from the front side of the glass panel and automatically engage with the support parts through the recessed parts. This self-service design eliminates the need for complex screw assembly operations, allowing users to easily assemble and disassemble the panel while maintaining strong connection strength through the interlocking mechanism.
3Ease of operation
If magnetic force is used to attach the panel, then the panel can be easily attached and detached, but the magnetic force weakens with repetitive opening and closing
Solution Approach 1:
The invention combines multiple attachment mechanisms: the mechanical interlocking through support parts with recessed parts and attachment parts, and the fastening members that secure the connection. This merged approach provides reliable, consistent attachment strength that does not degrade with repetitive use, while still maintaining ease of operation through simple assembly and disassembly processes.
4Manufacturing precision
If multiple recessed parts and attachment parts are provided for alignment, then the panel can be precisely positioned, but the assembly process becomes difficult
Solution Approach 1:
The recessed parts and attachment parts are designed to automatically align when the glass panel is placed on the frame. The fastening members insert through the attachment parts and engage with the support parts through the recessed parts in a self-aligning manner, eliminating the need for complex manual alignment operations while ensuring precise positioning of the panel.
