Dishwasher Control Module Mounting for Easy Front Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of dishwashers makes it difficult to access and disassemble the electronic control module, complicating its programming during assembly, as it is typically integrated into the assembly base and not easily removable.
Innovation Solution
The electronic control module is supported by a retaining contour on the wash compartment base wall, rather than the assembly base, allowing for easier assembly and disassembly, with elastic support sections and positioning stops for precise location and locking mechanisms for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic control module is integrated into the assembly base, then the structure is compact, but the accessibility and disassembly of the control module becomes difficult
Solution Approach 1:
The electronic control module is separated from the assembly base and positioned on the base wall of the wash compartment. This segmentation allows the control module to be independently accessible while maintaining a compact overall structure. The retaining contour on the base wall provides a dedicated mounting location that is easily accessible from the front of the dishwasher.
Solution Approach 2:
The retaining contour acts as an intermediary structure between the base wall and the electronic control module. It provides positioning stops and retention features that secure the module in place while allowing for easy installation and removal. This intermediary structure resolves the contradiction by providing both secure mounting and easy accessibility.
2Manufacturing precision
If positioning stops are provided to ensure correct location, then the positioning precision is improved, but the assembly complexity increases
Solution Approach 1:
The positioning stops are integrated into the retaining contour structure on the base wall. This merging of positioning and retention functions into a single structure achieves precise positioning without adding separate complex positioning mechanisms. The retaining contour combines multiple functions (retention, positioning, and alignment) in one element.
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
This design enables easy, tool-free assembly and disassembly of the electronic control module, reducing assembly complexity and allowing for more accessible programming, while maintaining secure positioning during operation.
Implementation Method 1
The supporting section is preferably designed so as to be elastic in order to absorb impact loads, during transportation or during the assembly of the dishwasher, onto the electronic control module.
