Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved pushing devices and carts that can efficiently and effectively move multiple wheeled objects, particularly in retail and warehouse environments, where existing solutions lack in maneuverability and efficiency when handling large numbers of carts or objects with varying sizes and configurations.
Innovation Solution
The development of a powered pusher system that includes a base with swivel and fixed wheels, a motor, and a guidance channel for easy coupling with various wheeled carts, allowing for automatic coupling and efficient movement of carts with features like deployable guidance wheels and detachable user platforms for enhanced maneuverability and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a powered pusher is used to move multiple carts, then productivity is improved, but device complexity increases due to the need for coupling mechanisms and guidance systems
Solution Approach 1:
The pusher system automatically couples with carts through the guidance channel mechanism. When the pusher approaches a cart, the guidance channel automatically guides the coupling components together without manual intervention, allowing the system to service itself during the coupling process.
Solution Approach 2:
The guidance channel acts as an intermediary element between the pusher and the carts. It provides a structured pathway that facilitates automatic coupling while simplifying the interaction between the pusher's coupling components and the cart attachment points.
2Ease of operation
If guidance channels are added to enable automatic coupling, then ease of operation is improved, but device complexity increases due to additional structural components
Solution Approach 1:
The guidance channel serves multiple functions: it guides the pusher into proper alignment, provides structural support for the coupling mechanism, and defines the coupling interface geometry. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The coupling system is divided into discrete segments: the guidance channel structure, the coupling components on the pusher, and the attachment points on the carts. This segmentation allows each component to be optimized independently while working together as an integrated system.
3Ease of operation
If swivel wheels are used at corners for better maneuverability, then ease of operation is improved, but stability deteriorates compared to fixed wheels
Solution Approach 1:
Different wheel locations have different functional requirements. Corner wheels use swivel casters to provide omnidirectional maneuverability where needed, while front wheels use fixed directional control where stability and straight-line movement are prioritized. Each location has the wheel type optimized for its specific operational context.
