Washing Machine Cover Assembly With Integrated Frame Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing coupling structures between the frame and electronic part accommodating plate in washing machines are inefficient, requiring additional parts and potentially compromising assembly quality due to the need for separate brackets and screws.
Innovation Solution
A connection unit with integrated holes and a guide system, including position determining protrusions and grooves, is provided to securely couple the electronic part accommodating plate to the frame, reducing the number of assembly parts and enhancing the assembly quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a separate bracket and screw are used to couple the electronic part accommodating plate and frame, then the coupling strength is improved, but the number of parts increases and assembly quality deteriorates
Solution Approach 1:
The connection unit integrates multiple functions into a single component: it combines the bracket structure with integrated connection holes and guide units, eliminating the need for separate brackets and screws. This merging of parts reduces assembly complexity while maintaining coupling strength between the electronic part accommodating plate and frame.
2Strength
If a separate bracket and screw are used to couple the electronic part accommodating plate and frame, then the coupling strength is improved, but the assembly quality deteriorates
Solution Approach 1:
The guide units (position determining protrusions and grooves) are pre-formed on the connection unit and frame respectively, establishing precise coupling positions before the actual assembly. This preliminary positioning action ensures high assembly quality and prevents misalignment, eliminating the need for complex alignment procedures during assembly.
3Ease of operation
If connection holes are provided on the connection unit, then the coupling between connection unit and frame is enabled, but the connection unit becomes more complex
Solution Approach 1:
The connection holes are integrated directly into the connection unit structure during molding, combining the bracket function with the fastening function. This integration enables coupling capability while avoiding the complexity of separate fastening components, as the holes are built-in features rather than added elements.
