Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing picnic tables are often too bulky or heavy for portability and lack adjustability in height, failing to accommodate the needs of different users.
Innovation Solution
A portable and adjustable picnic table design featuring rotatable supporting assemblies with adjustable supports, allowing the table height to be adjusted and the table and bench panels to be aligned for compact storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If picnic tables are made sturdy and functional, then they provide stable support and durability, but they become bulky and heavy, reducing portability
Solution Approach 1:
The picnic table is divided into separate panels (table top and bench panels) that can be detached from each other. Each panel can be carried independently, significantly reducing the weight burden on any single person and improving overall portability while maintaining structural integrity when assembled
Solution Approach 2:
The supporting assemblies incorporate rotatable connections between table supports and table panel, and between bench supports and bench panels. This dynamic design allows the table to be folded into a compact configuration for easy storage and transport, while providing stable support when in use
2Weight of moving object
If picnic tables are designed for portability, then they become lighter and easier to carry, but they lack adjustability in height, failing to meet diverse user needs
Solution Approach 1:
The table supports incorporate telescopic structures with adjustable lengths, allowing the height of the table panel relative to bench panels to be modified. This dynamic adjustment capability enables the table to adapt to different user height requirements while maintaining a compact, portable design when folded
Solution Approach 2:
The picnic table is designed with universal adaptability through height adjustment features, allowing it to serve different users with varying height requirements. The same portable structure provides both ease of transport and customized height accommodation for diverse user needs
3Ease of manufacture
If picnic tables have fixed structure, then they are simple to manufacture, but they cannot be folded for compact storage and transportation
Solution Approach 1:
The table is segmented into separate panels connected by supporting assemblies with rotatable joints. This segmentation enables the structure to be folded into a compact configuration for storage and transport, while maintaining relative structural simplicity through standardized connection mechanisms
Solution Approach 2:
The rotatable connections in the supporting assemblies enable the table to transition between extended (use) and folded (storage) configurations. This dynamic design allows compact storage without requiring complex manufacturing, using straightforward rotational joints

AI summary
A picnic table includes a table panel, one or more bench panels and a supporting frame to support the table and bench panels. The supporting frame includes first and second supporting assemblies, each including a table support and one or more bench supports. The supporting frame further includes a table frame and one or more bench frames. The table frame rotatably connects the table support of each of the first and second supporting assemblies with the table panel. Each bench frame rotatably connects a bench support of each of the first and second supporting assemblies with a bench panel. The table support of each of the first and second supporting assemblies is adjustable in length. Adjusting the length of the table support changes the height of the table panel with respect to the one or more bench panels.
