Method for installing a camera on an interior-compartment wall of a domestic appliance, and domestic appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of a camera in a household appliance, particularly in a household refrigeration appliance, is complex due to the need for thermal insulation between the interior compartment and the outer housing, requiring additional reinforcement parts and complex electrical connections, which increases installation effort.
Innovation Solution
A method involving a reinforcement part that is separate from the interior compartment and directly connected to the camera through a recess in the wall, allowing for a two-stage installation process with perpendicular and parallel movements to secure mechanical and electrical connections, eliminating the need for additional fastening elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reinforcement part is used to enable camera installation in the thermally insulated interior compartment, then the camera can be mechanically connected to the wall, but the installation complexity and electrical connection effort increase significantly
Solution Approach 1:
The patent combines the mechanical connection function and electrical connection function into a single integrated reinforcement part. The reinforcement part includes both mechanical fastening elements and electrical connection interfaces, allowing both mechanical and electrical connections to be established simultaneously in one installation step, rather than requiring separate operations.
Solution Approach 2:
The reinforcement part serves multiple functions: it provides mechanical support for the camera, establishes mechanical fastening through snap-fit connections, and simultaneously provides electrical connection interfaces. This multi-functional design eliminates the need for separate fastening elements and cable routing operations.
2Reliability
If additional fastening elements and cable connections are used to secure the camera, then the mechanical and electrical connections are established, but the installation effort and time increase
Solution Approach 1:
The electrical connection interfaces are pre-integrated into the reinforcement part during manufacturing. This preliminary action eliminates the need for separate cable routing and connection operations during installation, as the electrical connections are already positioned and ready to be connected when the camera is mounted.
3Temperature
If the reinforcement part is arranged in the intermediate space on the foam side, then thermal insulation is maintained, but the installation and positioning become more difficult
Solution Approach 1:
The reinforcement part acts as an intermediary element that bridges the interior compartment wall and the camera while maintaining the thermal insulation layer. It is designed to be integrated into the insulation structure, providing mounting functionality without compromising the thermal barrier.

AI summary
A method for installing a camera on a wall of an interior compartment of a domestic appliance has the following steps: providing a mounting part and a camera, which are separate from one another; fastening the mounting part at an aperture in the wall; moving the camera towards the mounting part along a first installation direction, which is perpendicular to the plane of the aperture, to join the camera and the mounting part through the aperture and to achieve an interim installation state, wherein the camera and the mounting part are arranged on the opposite sides of the wall; displacing the camera relative to the mounting part in a second installation direction, parallel to the plane of the aperture, until an end position of the camera on the mounting part is reached.
