Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mechanical designs for laundry treatment appliance front door handle assemblies are complex, leading to increased manufacturing costs and reduced production efficiency due to the large number of components required, and they often occupy valuable space, causing irritation to users.
Innovation Solution
A simplified handle assembly comprising a handle body, handle edge piece, and handle inner piece, where flexible tabs and hooks engage with corresponding slots to secure the handle components, reducing the number of parts and allowing for easier installation and durability during continuous use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional mechanical designs with multiple connection elements are used for the handle assembly, then the locking mechanism can be designed with various components, but the production efficiency decreases and manufacturing costs increase due to the large number of individual elements required
Solution Approach 1:
The patent combines multiple separate connection elements into a single integrated attachment component. The attachment component includes both the first engaging element (hook) and the second engaging element (ledge) as unified parts, eliminating the need for multiple individual connection elements. This merging reduces the number of components required for assembly while maintaining the versatility of the locking mechanism design.
2Adaptability or versatility
If traditional mechanical designs with multiple connection elements are used for the handle assembly, then the locking mechanism can be designed with various components, but manufacturing costs increase due to the large number of individual elements required
Solution Approach 1:
The patent merges multiple connection elements into a single attachment component that can be produced as one piece. This reduces manufacturing complexity and costs by eliminating the need to produce, inventory, and assemble multiple separate small parts. The unified component maintains all necessary engaging elements while simplifying the manufacturing process.
3Ease of operation
If conventional handle attachment components are used, then the handle assembly can be constructed, but the components occupy valuable space and cause irritation to the user's hand by forming a rough surface on the back of the handle
Solution Approach 1:
The attachment component is designed to nest within the limited space behind the handle. The first and second engaging elements are positioned to fit into recesses or cavities in the handle structure, allowing the component to occupy minimal space while still providing full functionality. This nesting approach eliminates protruding elements that would irritate the user's hand.
