Lifting Container Holder With Adjustable Depth and No-Slit Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container holders face challenges in stably supporting large containers due to shallow accommodation spaces and in easily retrieving small containers from deep spaces, while also requiring significant space and featuring unsightly slits that can catch containers.
Innovation Solution
A lifting container holder with a cylindrical outer cylinder and inner member that reciprocate, driven by a gear-based lifting unit, allowing for adjustable depth of the accommodation space without the need for slits, enabling stable support and easy retrieval of containers of varying sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a shallow-type accommodation space is used for small containers, then the container holder is compact, but large containers cannot be stably supported
Solution Approach 1:
The bottom wall is made movable in the vertical direction, allowing the accommodation space depth to be dynamically adjusted. When a large container is detected, the bottom wall moves downward to increase depth; when a small container is present, the bottom wall remains higher to maintain compactness. This dynamic adjustment resolves the contradiction between compact size and stable support for large containers.
2Reliability
If a deep-type accommodation space is used for large containers, then large containers are stably supported, but small containers fall to the lower side and are difficult to retrieve
Solution Approach 1:
The bottom wall's vertical movability allows the system to adapt to container size. For small containers, the bottom wall is positioned higher, keeping the effective depth appropriate for easy retrieval. For large containers, the bottom wall moves down to provide sufficient support depth. This dynamic adjustment eliminates the need for a permanently deep accommodation space.
3Adaptability or versatility
If a lifting mechanism with a movable bottom wall is implemented, then accommodation space depth can be adjusted, but a slit is required in the fixed circumferential wall which deteriorates appearance and can catch containers
Solution Approach 1:
The invention extracts the movable bottom wall from the traditional design where it would require a slit in the fixed circumferential wall. Instead, the bottom wall is made independently movable through a different mechanical linkage system (connecting rods and cranks) that does not require penetrating slits in the case wall, thereby eliminating the harmful catching effect while preserving depth adjustment capability.
4Adaptability or versatility
If a lifting mechanism with a movable bottom wall is implemented, then accommodation space depth can be adjusted, but the mechanism increases device complexity
Solution Approach 1:
The lifting mechanism is segmented into distinct functional components: the movable bottom wall, connecting rods, cranks, and a actuating force application point. This segmentation allows for modular design and simplifies the overall structure by breaking down the complex motion into manageable segments that can be independently optimized and assembled.
