Table structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional table structures for social occasions lack proper food presentation, lead to overcrowding and accidents due to mixed placement of cold and cooked food, inadequate illumination, and lack of automatic stopping functionality for guests accessing food.
Innovation Solution
A table structure with two layers of rotary plates, each equipped with anti-slip pads and safety rails, illuminated units, and an optional power sensor for automatic stopping, connected to a central post with a power cable for enhanced convenience and safety, allowing separate placement of cold and cooked food and reducing overcrowding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cold food and cooked food are placed on the same rotary plate, then the table structure is simple, but food presentation is poor and guests waste time looking for desired items
Solution Approach 1:
The single rotary plate is segmented into multiple rotary plates (first rotary plate for cooked food, second rotary plate for cold food, third rotary plate for beverages). This segmentation allows different types of food and drinks to be served on separate rotating surfaces, improving food presentation and making it easier for guests to locate desired items without wasting time searching through mixed arrangements.
Solution Approach 2:
The invention transitions from a single-plane arrangement to a multi-layer vertical structure with rotary plates at different heights. The first rotary plate is positioned above the table surface, the second rotary plate is positioned below the first, and the third rotary plate is positioned below the second. This dimensional change allows simultaneous access to multiple food categories without horizontal clutter.
2Quantity of substance
If more food items are placed on the limited table surface, then food variety increases, but the table surface becomes overcrowded and accidents occur
Solution Approach 1:
The invention utilizes vertical space by positioning rotary plates at different heights (above and below the table surface level). The first rotary plate is positioned above the table surface, the second rotary plate is positioned below the first, and the third rotary plate is positioned below the second. This multi-level vertical arrangement significantly increases the quantity of food items that can be served while maintaining safe spacing between items, preventing overcrowding and reducing accident risks.
Solution Approach 2:
The rotary plates are nested vertically around the central post, with each plate positioned at a different height level. This nested arrangement allows multiple food serving surfaces to coexist in a compact vertical configuration, maximizing food capacity while maintaining safe distances between items on each plate and between plates themselves.
3Device complexity
If only ceiling lamps provide illumination, then the structure is simple, but food freshness and dining atmosphere are not enhanced
Solution Approach 1:
Instead of relying solely on general ceiling illumination, the invention incorporates localized illumination units directly on the rotary plates. Each rotary plate is equipped with illumination units that provide targeted lighting to the food items on that specific plate. This local quality enhancement highlights food freshness and creates an appealing dining atmosphere while maintaining relatively simple overall structure.
Solution Approach 2:
The illumination units serve multiple functions: they enhance food presentation by highlighting freshness, create an appealing dining atmosphere, and provide functional lighting for guests to see food items on rotating plates. This multi-functionality achieves enhanced illumination effects without proportionally increasing structural complexity.
4Ease of operation
If the rotary plate rotates continuously, then food access is convenient, but the plate cannot stop when guests want to get food
Solution Approach 1:
The invention incorporates sensors that detect the presence of guests or the position of food items, providing feedback control for the rotary plate rotation. When a guest approaches or when food items reach the optimal serving position, the system automatically stops the rotation. This feedback mechanism enables both continuous rotation for convenient food access and automatic stopping when guests want to get food, resolving the contradiction between ease of operation and automation.
