Folding Table Locking Mechanism for Compact Storage and Load Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banquet tables are bulky, difficult to store, transport, and require significant space due to their large size and weight, and often have weak connections that cannot support heavy loads, making them inconvenient and costly to use and move.
Innovation Solution
A folding table design featuring a blow-molded plastic table top and movable support structures that can be easily collapsed and unfolded, with a locking mechanism that secures the table in both positions, allowing for compact storage and transportation, and constructed from lightweight yet durable materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional banquet tables are constructed with large table tops and folding legs, then the tables can accommodate large groups of people, but the tables require large storage areas and are difficult to transport
Solution Approach 1:
The table top is divided into two sections that can be folded relative to each other. The first section remains stationary while the second section folds along with its support structure, allowing the table to be collapsed to a fraction of its original size for storage and transport while maintaining full table capacity during use
Solution Approach 2:
The support structure incorporates movable components including a telescopic first support member with multiple sections that can extend and retract, and a second support member that folds relative to the table top. This dynamic structure allows the table to transition between expanded use configuration and compact storage configuration
2Adaptability or versatility
If conventional banquet tables are constructed with large table tops, then the tables can accommodate large groups of people, but the tables become difficult to move or transport
Solution Approach 1:
The support structure is divided into multiple independent movable components including a first support member with telescopic sections and a second support member that folds. This segmentation allows each component to be manipulated independently, enabling a single person to easily collapse and move the table without requiring multiple people to handle the entire structure
Solution Approach 2:
The incorporation of telescopic and folding mechanisms creates a dynamic support structure that can be easily collapsed to a compact size. The movable components allow the table to transition smoothly between extended and collapsed states, making it simple for one person to transport even though the table provides large capacity when in use
3Strength
If fold-in-half tables are constructed with stronger and thicker materials, then the tables can support significant weight, but the tables become heavier and more difficult to manufacture and transport
Solution Approach 1:
The table utilizes composite construction combining materials with different properties: the table top sections use materials providing surface strength and durability, while the support members use materials optimized for structural strength-to-weight ratio. This composite approach allows the table to support significant loads without requiring excessively thick or heavy single-material construction
Solution Approach 2:
The dynamic telescopic and folding mechanisms distribute structural loads across multiple moving components rather than requiring a single heavy rigid structure. The engineered movement paths and connection points in the telescopic and folding mechanisms ensure that load-bearing capacity is maintained through proper force distribution across the lightweight components
4Adaptability or versatility
If conventional banquet tables are constructed with extended length, then the tables can accommodate large groups of people, but the tables cannot be transported in typical passenger vehicles
Solution Approach 1:
The table top is segmented into foldable sections and the support structure is segmented into telescopic and folding members. When collapsed, the entire table reduces to a compact size that fits within typical passenger vehicle trunks or back seats, while maintaining full extended length and capacity when assembled for use
Solution Approach 2:
The telescopic first support member with retractable sections and the folding second support member create a dynamically compactable structure. These mechanisms allow the table to transition from its extended use length to a compressed transport configuration that fits within standard passenger vehicle cargo spaces

AI summary
A foldable table may include a table top and legs that are movable between an extended position and a collapsed position. The table top may include a first section and a second section that are connected by a hinge assembly. A locking member may be sized and configured to lock the hinge assembly in a fixed position. Advantageously, moving the legs between the extended and collapsed positions may cause the locking mechanism to move between the locked and unlocked positions. Thus, when the legs are in the extended position and the locking mechanism is in the locked position, the table top may be secured in the unfolded position.
