Remote-Controlled Service Cart for Shop Floor Logistics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current moveable service carts, tool boxes, and workstations are cumbersome and difficult to relocate in crowded shop environments, requiring manual pushing or pulling, which is inefficient and increases labor costs due to the need for multiple trips.
Innovation Solution
A remotely controllable service cart system equipped with a microcontroller, receiver, and drive system that responds to user commands, allowing the cart to move autonomously without manual intervention, using sensors and feedback mechanisms to navigate safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the service cart is made large in stature to hold more tools and equipment, then the cart can carry more items, but it becomes difficult to move around in a crowded shop environment
Solution Approach 1:
The patent replaces the manual mechanical pushing/pulling system with an automated drive system comprising a motor, wheels, and remote control circuitry. This allows the cart to move autonomously or be controlled remotely, eliminating the need for physical manual manipulation while maintaining the ability to navigate the shop environment.
Solution Approach 2:
The cart is divided into functional segments: a stationary base unit containing the drive mechanism and a movable cart unit containing the tool storage. This segmentation allows the heavy-duty base to provide power while the cart portion can be easily positioned, resolving the contradiction between carrying capacity and maneuverability.
2Ease of operation
If the technician manually pushes or pulls the service cart to relocate it, then the cart can be moved to different locations, but it requires significant physical effort and time
Solution Approach 1:
The manual mechanical effort of pushing/pulling is replaced with an automated motor-driven wheel system controlled by a remote control device. The technician simply operates the remote control to move the cart to the desired location, dramatically reducing both physical effort and the time required for relocation.
Solution Approach 2:
The cart becomes self-propelled through the integrated motor and wheel system, eliminating the need for external manual force. The cart serves itself by moving under its own power when commanded by the remote control, thereby reducing the time and effort the technician must invest in cart relocation.
3Productivity
If the technician leaves the service cart stationary and makes multiple trips to retrieve tools, then the cart remains in place, but productivity decreases due to increased time to complete tasks
Solution Approach 1:
The technician's repeated manual trips to retrieve tools are replaced by the automated remote-controlled cart that can deliver tools directly to the work location. The remote control system enables the cart to autonomously transport tools, significantly reducing the time the technician spends making multiple trips and thereby improving overall task completion efficiency.
4Ease of operation
If the service cart is equipped with wheels for rolling movement, then the cart can be relocated more easily, but it still requires manual pushing or pulling which is difficult given the size and weight
Solution Approach 1:
The manual force application through pushing/pulling is completely replaced by an electric motor system that provides the propulsive force. The motor, connected to the wheels through a transmission system, generates the necessary force to move the cart without requiring any physical strength from the technician, thereby maintaining mobility while eliminating the need for human muscular effort.
