Trivet system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trivet systems lack versatility in configuration, as they are either fixed in a single deployment mode or require complex mechanisms for transitioning between nested and deployed positions, limiting their adaptability and usability.
Innovation Solution
A trivet system comprising multiple coupled trivets that can move between nested and deployed configurations, utilizing hinges or elongate connectors for rotational and pivoting motions, allowing for adjustable geometry and deployment trajectories, along with features like radially extending tabs for handling and utensil rests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple trivets are coupled together to enable movement between nested and deployed configurations, then versatility and adaptability are improved, but device complexity increases
Solution Approach 1:
The trivet system is divided into multiple independent trivet units (first trivet, second trivet, third trivet) that can be coupled together. Each trivet unit functions independently but can be connected through hinges or elongate connectors, allowing the system to transition between nested and deployed configurations. This segmentation enables versatility without requiring a single complex mechanism, as each unit follows a simple coupling pattern.
Solution Approach 2:
The trivet system utilizes nesting by allowing the second trivet to be disposed within the perimeter of the first trivet in the nested configuration, and the third trivet to be disposed within the perimeter of the second trivet. This nested arrangement minimizes space when stored while maintaining simple individual trivet structures, avoiding the need for complex transformation mechanisms.
2Adaptability or versatility
If hinges or elongate connectors are used to couple trivets for rotational motion, then deployment flexibility is improved, but manufacturing complexity increases
Solution Approach 1:
The hinge mechanism serves multiple functions: it couples adjacent trivets together, enables rotational motion between nested and deployed positions, and maintains spacing between trivet units. This multi-functionality reduces the need for additional specialized components, simplifying manufacturing while providing diverse deployment options including straight-line, angled, and variable-angle configurations.
Solution Approach 2:
The hinge acts as an intermediary element between adjacent trivet units, facilitating controlled rotational motion without requiring direct complex mechanical linkages between the trivets themselves. This intermediary approach simplifies the overall manufacturing process by using a standardized coupling component that mediates the interaction between trivet units.
3Reliability
If a releasable locking mechanism is added to maintain nested configuration, then stability is improved, but device complexity increases
Solution Approach 1:
The releasable locking mechanism is designed to automatically engage and maintain the nested configuration without requiring additional actuators or complex control systems. The locking mechanism self-activates when the trivets are in the nested position, providing stability through passive mechanical engagement that can be easily released when deployment is desired, thus improving reliability without significantly increasing complexity.

AI summary
A trivet system comprises a first trivet and a second trivet coupled to the first trivet. The first trivet and the second trivet are moveable relative to one another between a position in which the second trivet is disposed within a perimeter of the first trivet, and a position in which the second trivet is disposed outside a perimeter of the first trivet. There may also be a third trivet coupled to the second trivet. The second trivet and the third trivet are movable relative to one another between a position in which the third trivet is disposed within a perimeter of the second trivet, and a position in which the third trivet is disposed outside a perimeter of the second trivet.
