Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable chairs and tables are bulky, difficult to set up, and occupy significant storage space, making them inconvenient for on-the-go use and storage.
Innovation Solution
A collapsible furniture design featuring a central hub with pivotable legs and arms that can be easily deployed and stowed using a push button, with leg and arm springs to automatically adjust positions, allowing for compact storage and quick deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional portable chairs are designed to be portable, then they can be moved easily, but they become bulky and occupy significant storage space
Solution Approach 1:
The chair components are designed to nest within each other when collapsed, with legs and arms fitting into designated spaces within the chair frame structure, creating a compact storage configuration that minimizes volume while maintaining ease of deployment through simple mechanical mechanisms
Solution Approach 2:
The chair is divided into separable components including legs, arms, and seat sections that can independently fold and collapse, allowing each segment to be compacted efficiently while maintaining simple operation through individual hinge and latch mechanisms
2Ease of operation
If conventional portable chairs require multiple setup steps, then they can be more stable when deployed, but they become difficult and time-consuming to set up and stow
Solution Approach 1:
The chair incorporates pre-positioned latches and spring-loaded mechanisms that are prepared in advance to automatically engage or disengage components during deployment, eliminating the need for sequential manual adjustments and reducing setup time to a single action
Solution Approach 2:
Spring-loaded latches and automatic locking mechanisms perform the locking and unlocking functions automatically when the chair is deployed or collapsed, eliminating the need for manual intervention in securing components and reducing both setup and stow time
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables portable furniture that can be easily set up and stowed with minimal steps, occupying less space for storage and deployment, enhancing convenience and usability.
Implementation Method 1
a leg spring disposed against each of the plurality of legs, the leg spring resiliently urging the legs into the deployed position
Implementation Method 2
an arm spring disposed against each of the plurality of arms, the arm spring resiliently urging the arms into the deployed position
Implementation Method 3
a push button spring urges the stopper to engage with the stowed position catch

AI summary
A collapsible furniture item, such as a chair or stool, can be easily interconverted between an in-use, or deployed, configuration and a stowed configuration. A single push button may be used to cause the legs of the furniture to automatically deploy from the stowed configuration. A latch on each leg may retain the furniture in either the deployed or the stowed configurations. Arms may pivotably extending from the legs to form a seat of a chair or stool, or a top of a table, for example. The arms may telescope to form different configurations for the chair. When stowed, at least a portion of the arms are disposed within a channel formed by the legs, resulting in a compact stowed configuration. In the stowed configuration, multiple devices may join together for ease of transportation.
