Household Appliance Camera Mounting with Snap-Fit Reinforcement Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex and labor-intensive process of mounting cameras in household refrigeration appliances, particularly due to the need for thermal insulation between the inner and outer housings, makes it difficult to achieve a secure and efficient electrical connection between the camera and reinforcement parts.
Innovation Solution
A modular design featuring a camera with a housing and a separate reinforcement part connected via snap-fit or screw connections, allowing for a simplified and stable mechanical and electrical connection, with the reinforcement part having a contact plate and coupling unit for secure positioning and snap-fit elements for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reinforcement part is used to enable camera fastening in thermally insulated household refrigeration appliances, then the camera can be securely mounted on the wall, but the mounting and positioning process becomes complex and labor-intensive
Solution Approach 1:
The camera assembly is divided into separate modular components: the camera unit with its housing and the reinforcement part with integrated electrical plug connectors. This segmentation allows each component to be manufactured independently and assembled through simple snap-fit connections, reducing mounting complexity while maintaining secure attachment
Solution Approach 2:
The electrical plug connectors are integrated directly into the housing of the camera and the reinforcement part. This merging of electrical connection functions into the structural components eliminates the need for separate cabling operations, simplifying the mounting process while ensuring reliable electrical connection
2Reliability
If connection interfaces are integrated in the reinforcement part or cabled through it, then electrical connection is achieved, but additional joining and cabling work is required after camera mounting
Solution Approach 1:
The electrical plug connectors are pre-positioned and integrated into the camera housing and reinforcement part during manufacturing. This preliminary action ensures that when the camera and reinforcement part are assembled, the electrical connection is automatically established without requiring additional cabling work, thereby improving mounting efficiency
Solution Approach 2:
The snap-fit connection mechanism automatically aligns and connects the electrical plug connectors when the camera housing is attached to the reinforcement part. This self-service feature eliminates the need for separate electrical connection operations, allowing the mounting process to complete both mechanical and electrical connections simultaneously

AI summary
A household appliance includes a camera with a housing and a first electrical plug connector in the housing. A reinforcement part separate from the camera is configured for direct connection to the housing through a cutout in a wall of the appliance such that the housing and the reinforcement part are disposed on opposite sides of the wall. The reinforcement part has a second electrical plug connector for connection to the first electrical plug connector. The second plug connector is a separate component provided on the reinforcement part by a snap-fit connection and/or in the mounted state the first electrical plug connector is snap-fitted to the second electrical plug connector by a snap-fit connection and/or the housing of the camera is connected in the mounted final state to the reinforcement part by a screw connection. A mounting method for the camera is also provided.
