Refrigerator Door Handle Fastening for One-Push Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator handle mounting processes require multiple operators and increased processes due to the need for stable connection with multiple fastening units, increasing time and labor.
Innovation Solution
A refrigerator with a simplified fastening unit system comprising a cap member, a first fastening member, and a second leaf spring fastening member that allows for easy mounting of the handle by pushing it toward the door, reducing the need for multiple operators and processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fastening units are used to securely connect the handle to the door, then the connection stability is improved, but the mounting process complexity and labor requirements increase
Solution Approach 1:
The patent combines multiple fastening units into a single integrated assembly where the first and second fastening members are pre-assembled together. This merging allows the entire fastening system to be installed in one operation by simply pushing the handle toward the door, eliminating the need for separate fastening operations and reducing mounting complexity while maintaining secure connection through the combined fastening units
2Reliability
If multiple fastening units are used to securely connect the handle to the door, then the connection stability is improved, but the time required for mounting increases
Solution Approach 1:
The first and second fastening members are pre-assembled into an integrated unit before installation. This preliminary action ensures that when the handle is pushed toward the door, all fastening units are simultaneously engaged in one motion, eliminating the time-consuming sequential fastening operations and significantly reducing mounting time while ensuring stable connection
3Reliability
If conventional fastening process is used with multiple operators holding the handle and door, then the connection stability is ensured, but the labor requirements increase
Solution Approach 1:
The integrated fastening member design allows the handle assembly to self-align and self-fasten to the door through a simple pushing motion. The first and second fastening members work together automatically to secure the connection without requiring external support or multiple operators to hold components during installation, making the operation simple and reducing labor requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces human labor and time required for handle mounting by allowing a single operator to securely attach the handle using a simple pushing operation, while also providing stability and ease of separation.
Implementation Method 1
a second fastening member formed as a leaf spring and mounted in the cap member to fix the insertion part inserted in the cap member
