Compactable Utility Table with Collapsible Frame and Spreader Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compactible centerfold utility tables lack an efficient mechanism for transitioning between storage and use modes, requiring cumbersome manual adjustments and lacking stability during expansion.
Innovation Solution
A collapsible tabletop-support frame with mode-changing handgrips and a vertical guide rod, allowing the tabletop sections to pivot from a compact side-by-side arrangement to an expanded end-to-end configuration, facilitated by a spreader linkage that maintains stability and closes the gap between sections during expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustments are used for transitioning between storage and use modes, then the table can be converted between modes, but the operation becomes cumbersome and difficult
Solution Approach 1:
The table employs a dynamic conversion mechanism where the tabletop and support frame can transition between expanded and compacted states through controlled movement. The leg units are designed to be movable relative to the tabletop support, enabling the table to dynamically change its configuration from a functional expanded state to a storage compacted state, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The table is divided into separable components including the tabletop, support frame, and leg units that can independently move relative to each other. This segmentation allows the table to be converted between modes through simple relative movements of discrete parts rather than complex manual adjustments, improving ease of operation while maintaining manageable device complexity.
2Volume of moving object
If the table is designed to be compactible, then storage space efficiency is improved, but stability during expansion and compaction deteriorates
Solution Approach 1:
The support frame and leg units are designed with dynamic stability features that maintain structural integrity during the transition between expanded and compacted states. The leg units move in a controlled manner relative to the tabletop support, ensuring stability is maintained throughout the conversion process while achieving compact storage volume.
Solution Approach 2:
The table design incorporates pre-planned structural features that cushion and guide the transition between modes. The movable leg units are positioned and configured to provide stable support during expansion and compaction, preventing instability before it can occur during the mode transition process.
3Volume of moving object
If the tabletop sections are arranged side-by-side in compact mode, then storage efficiency is improved, but the gap between sections remains open and unstable
Solution Approach 1:
The tabletop sections are designed to be movable relative to each other, transitioning from a compact side-by-side arrangement during storage to an expanded functional arrangement during use. This dynamic positioning ensures that when compacted for storage, the sections are deliberately positioned to minimize gaps and maintain stability, while allowing the gap to open naturally when expanded for use.
