Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional refrigerators lack an efficient mechanism for easily accessing storage bins, which are often buried deep within compartments, making retrieval of contents cumbersome and inconvenient.
Innovation Solution
A lift mechanism is integrated into the refrigerator, comprising a bin support structure, pivot arms, and a drive unit that allows the storage bin to be raised and lowered vertically, enabling easy access and improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If storage bins are positioned deep within refrigerator compartments to maximize storage capacity, then storage volume is improved, but accessibility and ease of operation deteriorate
Solution Approach 1:
The storage bin is transformed from a static fixed position to a dynamic movable position through the lift mechanism. The bin can be automatically raised to an accessible position or lowered to a storage position, allowing the system to adapt between maximizing storage capacity and improving accessibility based on operational needs.
Solution Approach 2:
The lift mechanism acts as an intermediary device between the user and the storage bin. Instead of directly accessing bins deep within the compartment, users interact with the control system which then operates the lift mechanism to bring the bin to an accessible position, mediating the interaction and solving the accessibility problem.
2Device complexity
If manual retrieval of storage bins is used to simplify the mechanism, then device complexity is reduced, but productivity and time efficiency deteriorate
Solution Approach 1:
The system provides self-service by automatically detecting when a storage bin needs to be accessed and initiating the lift sequence without requiring manual intervention. The control system monitors bin position and user interaction, then autonomously operates the lift mechanism to retrieve the bin, combining automation with relatively simple mechanical components.
Solution Approach 2:
The patent replaces complex manual mechanical operations with an automated control system that uses sensors, motors, and control logic to operate the lift mechanism. This substitution of manual mechanical systems with automated control achieves high productivity while keeping the mechanical structure relatively simple and manageable.
3Ease of operation
If automated lift mechanism is implemented to improve accessibility, then ease of operation is improved, but device complexity and manufacturing cost worsen
Solution Approach 1:
The lift mechanism is segmented into distinct functional modules: the drive unit for power generation, the pivot arm for motion transmission, and the bin support structure for carrying the load. This segmentation allows each component to be optimized independently and simplifies the overall design by breaking down the complex automated system into manageable, standardized subsystems.
Solution Approach 2:
The lift mechanism is designed with universal components that can serve multiple functions. The pivot arm both supports the bin weight and provides the lifting motion; the drive unit provides both lifting and lowering capabilities; the bin support structure accommodates various bin configurations. This multi-functionality reduces the number of specialized components needed, thereby reducing overall device complexity.
