Speech-Driven Work Handover on Conveyor Line Portable Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for work handover in production lines, such as those using speech recognition and synthetic speech for hands-free operation, do not support the efficient transfer of work between multiple workers, particularly in conveyor systems where multiple items are shared among workers, leading to inefficiencies and increased burden.
Innovation Solution
A portable terminal and management server system that enables hands-free work handover by associating work items with results and using speech recognition to transmit and receive work progress information between portable terminals and the server, allowing seamless transfer of work between workers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple workers share multiple items in a conveyor system, then worker burden is reduced and productivity is improved, but the complexity of managing work handover between workers increases
Solution Approach 1:
The portable terminal acts as an intermediary device that automatically manages work handover between workers. When a worker approaches the terminal, the system automatically transmits work information (including item details and current status) from the outgoing worker to the incoming worker without requiring manual intervention. This intermediary system resolves the contradiction by automating the complex handover management while enabling multiple workers to efficiently share multiple items.
2Productivity
If work handover is performed manually between workers, then system complexity is low, but time is lost during handover and productivity decreases
Solution Approach 1:
The system performs preliminary actions by pre-preparing work information for automatic transmission. The portable terminal is configured in advance with work information including item details, current status, and handover protocols. When handover is needed, the system automatically executes the transmission without requiring workers to manually transfer information, thereby eliminating time loss while maintaining simple operational procedures.
3Ease of operation
If speech recognition is used for hands-free operation, then worker safety and ease of operation are improved, but the ability to perform work handover between multiple workers is lost
Solution Approach 1:
The portable terminal is designed with multi-functionality to serve both individual hands-free operation and multi-worker handover purposes. The terminal includes speech recognition capabilities for hands-free input during individual work, while simultaneously具备 automatic work information transmission and reception functions for handover between workers. This universal design resolves the contradiction by enabling the same device to perform both hands-free operation and collaborative handover tasks.

AI summary
A portable terminal includes: a storage part which holds work information in which a plurality of items included in work are associated with respective work results; a speech recognition part which stores a work result(s) obtained by recognizing an utterance(s) of a worker in the storage part; and a communication part which transmits, when the speech recognition part recognizes a predetermined utterance(s) of a worker, a work result(s) held by the storage part to a management server or another (other) portable terminal(s). When the communication part receives a work result(s) from the management server or another (other) portable terminal(s), the communication part stores the received work result(s) in the storage part.
