Door for a domestic refrigeration device with a handle that can be slid without dismantling and domestic refrigerator and method for positioning a handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household refrigeration appliance freezer compartment doors require complex disassembly and reassembly to change the handle position, necessitating multiple components and significant assembly effort.
Innovation Solution
A freezer compartment door with a positioning device that allows the handle part to be changed between two stop sides without disassembly, using a displacement guide and coupling rod for smooth, user-friendly position adjustment, reducing the need for additional tools and components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle part is fixed to the door body using traditional fastening methods, then the handle position is stable and reliable, but changing the handle position requires disassembly and reassembly of multiple components
Solution Approach 1:
The positioning device is segmented into distinct functional elements: a displacement guide with guide slots, locking devices with locking elements, and a coupling mechanism. This segmentation allows the handle part to be independently positioned and locked without affecting other door components, enabling easy position changes while maintaining overall door integrity.
Solution Approach 2:
The positioning device transitions from a static fixed connection to a dynamic adjustable connection. The handle part can be easily displaced along the guide slots and locked into different positions using the locking devices, providing adaptability for different stop sides while maintaining stability when locked.
2Adaptability or versatility
If multiple separate components are used for the handle assembly to enable position changes, then the handle can be repositioned, but the assembly effort and time increase significantly
Solution Approach 1:
The positioning device merges multiple functions into a single integrated assembly: the displacement guide provides the movement path, the locking devices provide position fixation, and the coupling mechanism connects the handle to the door body. This consolidation allows position changes without requiring separate disassembly and reassembly operations for each component.
Solution Approach 2:
The locking elements are pre-configured in the locking devices at specific positions along the guide slots. When the handle is displaced to a desired position, the locking elements are already in place to immediately secure the handle without requiring additional assembly steps or adjustments.
3Adaptability or versatility
If the handle part is permanently fixed to the door body, then the assembly is simple and robust, but the handle cannot be repositioned for different stop sides
Solution Approach 1:
The positioning device acts as an intermediary between the handle part and the door body, providing a controlled connection that allows for position changes while maintaining reliability. The locking devices serve as mediators that secure the handle at specific positions, ensuring connection reliability without permanent fixation.
Solution Approach 2:
The connection parameters between the handle and door body are changed from fixed to adjustable. The locking devices enable discrete position changes along the guide slots, allowing the handle to be repositioned for different stop sides while maintaining a reliable locked connection at each position.
4Ease of operation
If traditional fastening methods are used for the handle, then the assembly is simple, but additional tools and disassembly procedures are required for position changes
Solution Approach 1:
The positioning device is designed to be self-servicing for position changes. The locking elements automatically engage with the guide slots when the handle is displaced to a new position, eliminating the need for additional tools or complex assembly procedures. The user can simply move the handle along the guide and the locking mechanism takes care of securing it in place.
