Ice compartment with driving unit, ice maker and household cooling appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ice maker systems in household cooling appliances face issues with unstable mounting and noise due to the attachment of individual parts, leading to problems with freezing and noise generation.
Innovation Solution
The design incorporates a driving unit with a drive housing featuring first and second receiving ducts for secure fastening to the inner liner wall of the refrigeration compartment, allowing for simple and stable mounting of the ice compartment, using offset ducts for enhanced retention and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual parts are merely attached to the driving unit, then the mounting is simple, but the stability and noise reduction are insufficient
Solution Approach 1:
The patent merges multiple fastening functions into an integrated drive housing structure with receiving ducts that guide fastening parts through the housing to secure it to the inner liner wall. This integration ensures stable mounting while maintaining simplicity by providing pre-defined fastening pathways.
Solution Approach 2:
The receiving ducts act as intermediary structures that mediate between the fastening parts and the drive housing. These ducts guide and position the fastening parts to ensure proper alignment and stable connection to the inner liner wall, resolving the contradiction between simple attachment and stable mounting.
2Device complexity
If individual parts are merely attached to the driving unit, then the device complexity is low, but noise generation increases
Solution Approach 1:
The drive housing integrates multiple functions including structural support, noise containment, and fastening guidance into a single component. This merging reduces the need for separate noise-reduction elements while maintaining low device complexity and effectively reducing noise generation.
3Ease of manufacture
If functional elements are arranged on the housing, then the mounting is simple, but freezing performance deteriorates
Solution Approach 1:
The drive housing is designed with specific local features including receiving ducts positioned to avoid interference with freezing operations. The housing material and structure are optimized for specific regions to ensure both simple mounting and effective freezing performance, with the drive motor and functional elements arranged in locations that do not compromise the freezing process.

AI summary
An ice compartment of a household cooling appliance has a driving unit for driving an ice storage container of an ice maker. The driving unit has a drive housing and at least one drive motor. A first receiving duct accommodates a first fastening part and extends completely through the drive housing. The drive housing can be fastened by the first fastening part to an inner liner wall of the refrigeration compartment. The first receiving duct extends across the entire depth of the drive housing and is open at a front end and a rear end. A second receiving duct extends completely through the drive housing. The drive housing can be fastened by the second fastening part to the same inner liner wall of the refrigeration compartment. The second receiving duct extends across the entire depth of the drive housing and is open at a front end and a rear end.
