Powered Pusher With Swivel Wheels For Cart Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved pushing devices and carts that can efficiently and effectively move large numbers of wheeled objects, such as carts, in retail and warehouse environments, where existing solutions lack maneuverability and ease of use, especially when dealing with carts of varying sizes and loads.
Innovation Solution
A powered pusher system with a base, control handles, rear swivel wheels, and front fixed wheels, equipped with a motor and latching mechanism, allowing for easy coupling and uncoupling from wheeled objects, and featuring a guide handle for remote control operation, enabling efficient movement of carts with a minimal turning radius and easy directional control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a powered pusher is used to move carts, then productivity is improved, but device complexity increases
Solution Approach 1:
The powered pusher is divided into modular components including a base unit with motor, a separate coupling mechanism with latching component, and detachable control handles. This segmentation allows the system to maintain high productivity while reducing operational complexity, as each module performs a specific function and can be independently maintained or replaced.
Solution Approach 2:
The powered pusher base unit is designed with universal compatibility to work with multiple types of carts and wheeled objects through standardized coupling mechanisms. The motorized propulsion system serves multiple functions including pushing, pulling, and maneuvering various cart configurations, thereby improving productivity without proportionally increasing device complexity.
2Weight of moving object
If the pusher is designed for heavy loads, then it can handle more weight, but maneuverability deteriorates
Solution Approach 1:
The pusher employs dynamic wheel configurations with swivel rear wheels that can rotate 360 degrees and fixed front wheels that provide stable propulsion. This dynamic design allows the system to easily navigate tight spaces and change directions while maintaining the capability to handle heavy loads up to 200 kg, resolving the contradiction between load capacity and maneuverability.
Solution Approach 2:
The control handles are positioned at an elevated height above the base, creating a vertical dimension separation between the heavy motorized base and the lightweight control interface. This dimensional arrangement allows the operator to easily maneuver the system with minimal effort while the motor handles the heavy lifting, enabling both heavy load capacity and easy operation.
3Ease of operation
If automatic coupling is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The coupling mechanism features a self-latching system where the latching component automatically engages with the cart's coupling interface when brought into proximity. The spring-biased latching arm automatically secures the connection without requiring manual intervention, thereby improving ease of operation while keeping the device complexity manageable through the use of simple mechanical self-service components.
4Volume of moving object
If the base is made compact, then it is easier to maneuver, but the motor and components may not fit
Solution Approach 1:
The motor, battery, and control electronics are nested within the compact base structure in a space-efficient arrangement. The motor is positioned centrally with the battery mounted above it, and the wheel assemblies are integrated into the base perimeter. This nesting approach allows the base to maintain a compact volume while accommodating all necessary components for handling various cart types and loads.
