Chair transport system
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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
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.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables secure, damage-free transport of chairs by integrating them with other equipment, allowing for efficient stowing and unloading, and reducing the risk of damage during transport.
Implementation Method 1
The system is supported on the floor via the chair's casters
Implementation Method 2
each of whose frame arms is provided with at least one rotatably mounted caster
