Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transporting stacked chairs are unstable and difficult to maneuver manually due to the lack of effective support during movement.
Innovation Solution
A movable vehicle with a base frame, roller, and adjustable V-shape supporting frame, comprising first and second supporting arms, which provides stable support and adjustable positioning for different chair models, enhancing flexibility and safety during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If stacked chairs are transported directly on a flat plate, then the transportation tool is simple, but the stability and ease of manual handling deteriorate
Solution Approach 1:
The supporting frame acts as an intermediary between the flat plate and the stacked chairs. It provides a specialized interface with V-shaped arms that cradle the chair legs, preventing sliding and improving stability during transport without requiring a completely complex device structure.
Solution Approach 2:
The supporting frame incorporates adjustable components that can adapt to different chair configurations. The frame can be adjusted to accommodate various chair sizes and stacking arrangements, providing dynamic adaptability while maintaining overall structural simplicity.
2Ease of manufacture
If a fixed supporting structure is used, then the manufacturing is simple, but the adaptability to different chair models deteriorates
Solution Approach 1:
The supporting frame uses adjustable mechanisms that allow it to adapt to different chair models. The frame can be reconfigured to accommodate various chair dimensions and stacking patterns, providing versatility without requiring multiple specialized structures for each chair type.
Solution Approach 2:
The supporting frame is designed as a universal solution that can handle multiple types of stackable chairs. Through its adjustable features, a single frame structure serves multiple functions across different chair models, eliminating the need for model-specific supporting structures.
3Device complexity
If no supporting frame is provided, then the device complexity is low, but the ease of manual operation deteriorates
Solution Approach 1:
The supporting frame serves as a mediator between the operator and the stacked chairs. It provides hand grips and a stable structure that facilitates easy manual pushing and maneuvering, making the transport operation straightforward without adding excessive structural complexity.
Solution Approach 2:
The supporting frame is designed to enable self-service operation. The structural features naturally provide handholds and stable positioning, allowing users to easily grasp and maneuver the loaded vehicle without requiring additional operational mechanisms or complex controls.

AI summary
A movable vehicle capable of carrying stackable chairs comprises a base frame, a roller connected to the base frame for carrying the base frame, and a supporting frame disposed in the base frame. The supporting frame has a V-shape support with an upward opening. Advantages include adjustability of the supporting frame for placing and moving the stackable chair, and the V-shape of the supporting frame can either be an upward convex column, or an upward board, so as to carry different stackable chairs.
