Door and clothes treating apparatus having the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing production methods for door handles of clothes treating apparatuses involve separate production and assembly, leading to increased material costs and reduced productivity due to additional processing steps.
Innovation Solution
The door handle is formed integrally with the door, featuring a cover frame and cover panel with protrusion and recessed portions to create a hand-receiving space, supported by ribs and hooks for structural integrity and assembly, eliminating the need for separate production and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the door handle is produced as a separate part to be assembled to the door, then the door handle can be independently manufactured and replaced, but material costs increase and productivity decreases due to additional assembly processes
Solution Approach 1:
The patent merges the door handle with the door body by forming the handle as an integrated protrusion from the door's cover panel, eliminating the need for separate manufacturing and assembly processes. This integration directly resolves the productivity issue while maintaining manufacturing feasibility through molding techniques.
Solution Approach 2:
The door's cover panel is designed to serve multiple functions: it forms the door's external appearance, provides structural support, and creates the hand-receiving space for operation. This multi-functionality eliminates the need for a separate handle component while maintaining ease of manufacture.
2Ease of manufacture
If the door handle is produced as a separate part to be assembled to the door, then the door handle can be independently manufactured, but material costs increase due to production of additional parts
Solution Approach 1:
The door handle is merged with the door body as an integrated structure, reducing the total quantity of parts and materials required. The handle is formed as a protrusion from the existing door cover panel, eliminating redundant material usage and reducing overall material costs.
Solution Approach 2:
The door cover panel is designed to simultaneously provide the door's external appearance and form the functional handle structure, reducing the need for additional materials that would be required for a separate handle component.
3Ease of manufacture
If the door handle is produced as a separate part to be assembled to the door, then the door handle can be independently manufactured, but additional assembly processes are required which deteriorate productivity
Solution Approach 1:
The door handle is merged with the door body as an integrated structure formed during the door's manufacturing process, eliminating separate assembly steps. This reduces device complexity in the assembly process while maintaining manufacturing flexibility through molding design.
Solution Approach 2:
The door cover panel is designed to simultaneously provide the door's external appearance and form the functional handle structure, eliminating the need for separate assembly processes and reducing overall process complexity.
