Foldable Table Leg Assembly for Compact Tool-Free Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional table devices occupy a large area when not in use and require tools for assembly or disassembly, making them inconvenient to store and carry.
Innovation Solution
A detachable table device with a foldable leg system that includes a table top with an annular engaging groove and pivotable leg members, allowing the table to be easily attached or detached without tools, and folding into a compact state for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the table device uses unfolded legs, then the table top is supported stably, but the device occupies a large area when not in use
Solution Approach 1:
The leg device is divided into multiple leg members that can be independently folded and detached. Each leg member can be separated from the table top, allowing the table to be disassembled into compact components for storage, thereby reducing the occupied area while maintaining stability during use
Solution Approach 2:
The leg members are designed with pivot units that enable dynamic transformation between extended (supporting) and folded (compact) states. This dynamic capability allows the table to adapt its configuration - providing stable support when needed and compact storage when not in use
2Stability of the object's composition
If the table device uses conventional assembly, then the structure is stable, but tools are required for assembly or disassembly
Solution Approach 1:
The engaging groove and engaging end portion form a self-locking mechanism that automatically secures the leg members to the table top without requiring external tools. The structural design inherently provides both assembly functionality and structural stability, eliminating the need for separate assembly tools while maintaining strong connections
3Area of stationary object
If the leg members are pivotable for folding, then the table can be compacted, but the engagement mechanism becomes more complex
Solution Approach 1:
The pivot unit and engaging mechanism are merged into an integrated design where the same structural elements serve both functions. The engaging groove and end portion simultaneously enable folding motion and provide secure engagement, reducing the need for separate complex mechanisms while achieving both compactability and reliability

AI summary
A detachable table device includes a foldable leg device detachably connected to a table top and operable to support the table top when in an extended state and to separate from the table top when in a folded state. A circumferential portion of the table top has an inner annular surface formed with a radially and outwardly extending annular engaging groove. The leg device includes a pivot unit for interconnecting at least three leg members such that the leg members are pivotable relative to the pivot unit to be angularly equidistant when the leg device is in the extended state, and to be moved toward each other when the leg device is in the folded state. Each leg member includes an engaging end portion disposed movably in and engaging releasably the engaging groove in the circumferential portion of the table top.
