Solution Overview

Problem

Traditional collapsible stools are uncomfortable, difficult to transport, and unstable on uneven terrain, failing to securely adhere to the ground surface, which can lead to instability and potential injury.

Innovation Solution

A collapsible stool design featuring a base with a plurality of teeth for engaging the ground surface, an adjustable elongated rod with a ball-and-socket joint for stability, and additional features like a rotatable seat, storage compartments, and a retractable handle for enhanced usability and portability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional portable seating options are used, then the stool can be transported, but it becomes difficult to transport and uncomfortable to use

Engineering Contradiction:

ImprovecomfortabilityVSAvoidtransport difficulty

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The stool is divided into multiple collapsible sections that can be folded together into a compact form for easy transport, yet expand to provide a comfortable seating surface when deployed

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stool employs adjustable and collapsible components that transition between compact and expanded states, allowing it to adapt between portability mode and comfortable seating mode

Inventive Principle:

Principle #15Dynamics

2Reliability

If traditional seating options are used on uneven terrain, then the stool can be placed, but it causes instability and potential tipping

Engineering Contradiction:

ImprovestabilityVSAvoidcomfortability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The base incorporates teeth at specific locations that can penetrate uneven ground surfaces, providing localized stabilization points that ensure the stool remains stable and level even on irregular terrain

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The teeth are designed as simple, robust protrusions that can be easily manufactured and replace if needed, providing reliable ground engagement without complex mechanisms

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If the stool base is designed for ground engagement, then stability is improved, but the structure becomes more complex

Engineering Contradiction:

ImprovestabilityVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The base is designed with multiple discrete teeth rather than a single complex anchoring mechanism, allowing each tooth to independently engage the ground and provide stabilization

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using a complex mechanism to achieve ground engagement, the design uses simple protruding teeth that passively engage the ground through their geometry alone, inverting the approach from active mechanism to passive geometric engagement

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A collapsible stool entertainment system. The collapsible stool entertainment system includes an elongated rod having a first end opposite a second end. A seat portion is affixed to the first end and a base portion is affixed to the second end. A plurality of teeth extends from a lower surface of the base portion to engage a ground surface for additional stability. In some embodiments, the second end of the elongated rod is pivotally secured to an upper surface of the base portion via a ball-and-socket joint system, wherein the second end comprises a ball removably securable within a socket disposed on the base portion.
