Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work systems face challenges in efficiently replacing feeder carriages in component-mounting devices, particularly in automating the process for labor-saving and automation purposes.
Innovation Solution
A work system that integrates a mounting system with a feeder carriage transfer method using an unmanned conveyance system. This system includes a base with a board positioner, a feeder carriage that can be attached and detached, a connection mechanism, a part feeder, and a mounting head. The unmanned conveyance system uses notifiers and processors to coordinate the arrival and release notifications, enabling the feeder carriage to be transferred between the base and the conveyance vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual replacement of feeder carriage is used, then operational flexibility is maintained, but labor efficiency is reduced and automation level is low
Solution Approach 1:
The patent introduces an unmanned conveyance vehicle as an intermediary between the base and the feeder carriage replacement process. The conveyance vehicle autonomously transports feeder carriages and coordinates with the base through standardized communication protocols, automating the replacement task while managing system complexity through modular design.
Solution Approach 2:
The patent implements bidirectional notification mechanisms where the base sends arrival notifications to the conveyance system and receives release notifications in response. This feedback loop enables automated coordination of feeder carriage replacement operations, allowing the system to autonomously manage the replacement process based on real-time status information.
2Productivity
If automated conveyance system is implemented, then labor efficiency is improved, but coordination complexity between systems increases
Solution Approach 1:
The patent divides the automated replacement system into distinct functional modules: the base with its control unit, the unmanned conveyance vehicle with its processor, and the feeder carriages. Each module operates independently with well-defined interfaces through standardized notification protocols, enabling automated coordination while managing overall system complexity through functional segmentation.
Solution Approach 2:
The patent creates a universal communication interface between the base and conveyance system using standardized notification types (arrival notifications, release notifications). This universal protocol allows different components to interact through a common language, improving productivity while reducing coordination complexity through standardization.
3Extent of automation
If feeder carriage replacement is automated, then manual intervention is reduced, but system coordination requirements increase
Solution Approach 1:
The patent enables the unmanned conveyance vehicle to autonomously perform feeder carriage replacement operations without manual intervention. The conveyance system self-coordinates with the base through automated notification exchanges, detecting when feeder carriages need replacement and executing the swap independently, thereby maximizing automation while simplifying operation through self-service capability.

AI summary
A work system includes a mounting system which mounts a component on a board and an unmanned conveyance system having an unmanned conveyance vehicle. The unmanned conveyance system includes a first notifier which notifies the mounting system of an arrival notification indicating that the unmanned conveyance vehicle transfers the feeder carriage to a position where an operation of connecting the feeder carriage to the base starts, and a first processor which causes the unmanned conveyance vehicle to travel in a direction away from the base upon receiving, from the mounting system, a connection completion indicating that a connection of the feeder carriage is completed. The mounting system includes a second processor which causes the connection mechanism to connect the feeder carriage upon receiving the arrival notification, and a second notifier which notifies the unmanned conveyance system of the connection completion upon being informed of completion of the connection.
