Dishwasher Door Hinge Mounting Integrated Into Wall Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwashers require complex and costly assembly processes for attaching holding devices, which increases manufacturing time and costs due to the need for separate attachment of bearing bolts and hinge levers.
Innovation Solution
Designing the holding device and bearing bolt as a single, monolithic unit that is cast or injected directly into the dishwasher's wall elements, eliminating the need for subsequent attachment and enhancing structural integrity by providing a secure, form-fitting integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the holding device and bearing bolt are attached separately to the wall element, then the assembly process becomes complex and costly, but the structural integrity is maintained
Solution Approach 1:
The holding device and bearing bolt are merged into a single monolithic unit that is cast or injected directly into the wall element during manufacturing. This eliminates the need for separate attachment operations, reducing assembly complexity and cost while maintaining structural integrity through the integrated design.
Solution Approach 2:
The holding device is pre-formed and embedded into the wall element during the wall element manufacturing process itself, rather than being attached afterward. This preliminary integration simplifies subsequent assembly operations and reduces the number of manufacturing steps required.
2Ease of manufacture
If the holding device is embedded in the wall element, then assembly costs are reduced, but the ability to withstand tensile and compressive stresses must be ensured
Solution Approach 1:
The holding device and wall element are merged into a single integrated structure through casting or injection molding. This monolithic construction ensures continuous material flow and bonding between the holding device and wall element, providing superior tensile and compressive strength compared to mechanically attached alternatives while reducing assembly costs.
Solution Approach 2:
The solution utilizes composite construction where the holding device (made of metal or rigid plastic) is embedded in and bonded to the wall element material. This composite structure combines the strength properties of different materials to achieve both cost-effective manufacturing and high stress resistance.
3Productivity
If the holding device is cast or injected into the wall element, then the manufacturing process is simplified, but the form-fitting integration must provide secure door operation
Solution Approach 1:
The holding device is pre-positioned and embedded in the wall element during manufacturing with precise dimensional control. The casting or injection process creates a form-fitting integration that ensures proper alignment and secure mounting for door pivoting operations, eliminating the need for subsequent adjustment while maintaining reliability.
Solution Approach 2:
The injection molding process uses liquid material that flows under pressure to completely fill and bond around the holding device, creating a secure form-fitting integration. The hydraulic pressure ensures complete penetration and bonding, providing reliable structural support for door operation while simplifying the manufacturing process.
