Refrigerator drawer and refrigerator having the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator drawers often detach from their supporting members when pulled out, limiting their forward movement and compromising stability, which restricts the usable storage space and increases the risk of the drawer falling.
Innovation Solution
A refrigerator drawer design that incorporates a guide member with ribs and a securing mechanism, allowing the storage box to move forwardly while being secured to the supporting member, using rollers and stoppers to manage motion and prevent falling, with additional guiding slots and securing members for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the drawer is pulled out to increase extracting distance, then the usable storage space is improved, but the drawer may detach from the supporting member causing instability
Solution Approach 1:
The drawer system is divided into three main components: the storage box, the guide member attached to the storage box, and the supporting member fixed to the cabinet. The guide member is further segmented into a body portion and a protruding portion with guiding slots. This segmentation allows the storage box to move forward independently while the guide member maintains connection with the supporting member through rollers, solving the contradiction by separating the moving function from the stabilizing function.
Solution Approach 2:
The guide member acts as an intermediary between the storage box and the supporting member. It includes rollers that engage with the supporting member to prevent detachment, while simultaneously allowing the storage box to move forward. The guiding slots in the guide member provide a controlled path for movement, ensuring stability is maintained even as extracting distance increases.
2Ease of operation
If the drawer is allowed to detach forwardly, then ease of operation is improved, but the drawer may fall down compromising stability
Solution Approach 1:
The system transitions from a static fixed connection to a dynamic controlled movement system. The guide member with its guiding slots and rollers enables the drawer to move dynamically when needed while maintaining controlled engagement with the supporting member. This dynamic design allows easy operation during movement while preventing complete detachment and falling, resolving the contradiction between ease of operation and stability.
3Reliability
If the guide member motion is limited, then stability is improved, but the forward movement distance is restricted
Solution Approach 1:
The solution adds a vertical dimension to the connection system. The guide member extends downward with guiding slots that receive rollers from the supporting member, creating a vertical engagement that prevents detachment. This vertical dimension allows the storage box to move forward horizontally without compromising the connection stability, effectively resolving the contradiction between limited motion and movement distance.
