Wall Adjustment Contour for Stable Appliance Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliances face challenges in securely fastening built-in parts within the receiving space without compromising the available volume or accessibility, often resulting in unstable attachment and misalignment.
Innovation Solution
The design incorporates an elongate projection on the adjustment contour that faces away from the receiving space, allowing for precise positioning and enhanced support of the holding part, which is coupled to the adjustment contour, enabling secure and stable fastening of built-in parts without reducing the receiving space volume or impairing accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting bracket is used to attach components inside the housing, then the attachment stability is improved, but the available volume of the receiving space is reduced
Solution Approach 1:
The invention extracts the mounting function from the interior of the receiving space by positioning the adjustment contour and holding part on the outer surface of the wall element. This allows the component to be mounted outside the receiving space while still achieving stable attachment, thereby resolving the contradiction between attachment stability and available volume.
2Reliability
If a mounting bracket is used to attach components, then the attachment stability is improved, but the accessibility of the receiving space is impaired
Solution Approach 1:
By relocating the mounting structure (adjustment contour and holding part) to the outer surface of the wall element, the invention removes the mounting bracket from the interior of the receiving space. This extraction ensures that shelves, pull-out devices, and storage trays can be freely inserted and accessed without obstruction, while attachment stability is maintained through the external mounting structure.
3Ease of manufacture
If the adjustment contour is positioned inside the receiving space, then the component can be attached, but the spatial restriction of the receiving space occurs
Solution Approach 1:
Instead of positioning the adjustment contour inside the receiving space as in conventional designs, the invention inverts the approach by placing the adjustment contour on the outer surface of the wall element. This inversion allows the holding part to extend into the receiving space for component attachment while the bulk of the mounting structure remains outside, thus avoiding spatial restriction.
4Manufacturing precision
If a projection is added to the adjustment contour for positioning, then the positioning precision is improved, but the device complexity increases
Solution Approach 1:
The invention applies local quality by adding a projection only at the specific location on the adjustment contour where positioning is required. This localized feature provides precise positioning for the holding part without requiring complex modifications to the entire adjustment contour structure, thus achieving high positioning precision with minimal increase in device complexity.
