Solution Overview

Problem

Chairs are not robust enough for easy transportation and pose challenges during event setups, as they cannot be stowed away as efficiently as conventional transport cases, leading to potential damage.

Innovation Solution

A chair transport system comprising a transport case with side walls and a base plate, where the chair is connected to the case using rollers and a connecting device, allowing the chair to be fully immersed in the case and supported by its wheels, ensuring easy movement and protection during transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chairs are transported separately without integration into transport cases, then they can be moved freely, but they are vulnerable to damage and cannot be stowed efficiently

Engineering Contradiction:
Improvechair protectionVSAvoidtransport system integration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the chair with the transport case by integrating the chair frame into the case structure. The chair's frame arms are received by receiving elements in the transport case, and the casters are positioned on the base plate, creating a unified transport unit that protects the chair while enabling efficient stowing alongside other equipment cases.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transport case is designed to serve multiple functions: it protects the chair during transport, provides a standardized container for efficient stowing in vehicles, and maintains the chair in an upright position. The receiving elements and base plate configuration enable the case to handle both the chair and other equipment simultaneously.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Strength

If chairs are designed with fixed robust structures for transport durability, then they can withstand transport stresses, but they lose mobility and cannot be easily repositioned

Engineering Contradiction:
Improvetransport robustnessVSAvoidchair mobility
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent maintains chair mobility by retaining the casters on the frame arms, which can rotate and swivel to allow easy repositioning. The dynamic caster mechanism is integrated into the transport case through receiving elements that guide and support the casters during transport, allowing the chair to be both mobile during use and protected during transport.

Inventive Principle:
Principle #15Dynamics

3Reliability

If chairs are fully enclosed in transport cases for maximum protection, then damage is prevented, but the casters cannot contact the floor for movement

Engineering Contradiction:
Improvechair protectionVSAvoidtransport friction
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent segments the transport case into a main enclosed portion and an open base plate area. The base plate features openings or recesses that allow the casters to protrude through and contact the floor, enabling movement. The receiving elements are positioned to protect the chair frame while permitting caster access to the external environment for rolling motion.

Inventive Principle:
Principle #1Segmentation
