Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting lines, operators face challenges in completing component replenishment work within the allotted time, leading to potential disruptions in component supply and reduced production efficiency due to unperformed replenishment tasks.
Innovation Solution
A component replenishment management system that identifies and prioritizes component supply devices needing replenishment based on their supply state, allowing operators to focus on critical tasks within the work allowable time, ensuring continuous component supply and maintaining production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator performs component replenishment work in order while moving on the movement route according to the schedule, then the work is organized systematically, but the work allowable time may elapse before all work is finished
Solution Approach 1:
The system performs preliminary identification of replenishment target devices and calculates optimal movement routes before the operator begins work. The replenishment target identification unit identifies which component supply devices need replenishment in advance, and the movement route calculation unit computes the optimal path considering work allowable time constraints, allowing the operator to execute pre-planned actions efficiently
Solution Approach 2:
The system dynamically adjusts the movement route and replenishment priorities based on real-time component consumption states and production requirements. The extraction unit dynamically determines the optimal sequence of replenishment tasks by considering the work allowable time constraint and the urgency of each component supply device's replenishment need
2Reliability
If the operator follows the scheduled replenishment work order, then all replenishment tasks can be identified, but critical replenishment work may not be completed within the work allowable time
Solution Approach 1:
The system applies different priorities to different replenishment tasks based on their criticality to production. The extraction unit identifies which replenishment tasks are most critical to complete within the work allowable time and prioritizes those tasks in the movement route, rather than treating all replenishment tasks equally
Solution Approach 2:
The system continuously monitors the component consumption state of each supply device and provides feedback to update the replenishment priorities and movement route. The replenishment target identification unit tracks component supply states in real-time and adjusts the replenishment plan based on current production needs and consumption rates
3Ease of operation
If component replenishment work is not completed within the work allowable time, then the operator can maintain a steady pace, but component supply may be stopped and production efficiency lowered
Solution Approach 1:
The system pre-calculates the optimal movement route and identifies replenishment targets before the operator begins work, allowing the operator to maintain a steady pace while knowing exactly which tasks to perform and in what order, preventing delays that would disrupt production
Solution Approach 2:
The system automatically determines the optimal replenishment sequence and movement route based on component consumption data and production requirements, eliminating the need for the operator to make complex decisions about task prioritization and enabling them to focus on executing the pre-determined plan efficiently

AI summary
In a component replenishment management system, a setting unit sets work allowable time of an operator in a work area, a replenishment target identification unit identifies component replenishment target devices which are targets of component replenishment work by the operator, and a work progress determination unit determines a progress state of the component replenishment work. Then, an extraction unit extracts the component replenishment target devices for which the component replenishment work is to be performed before work time in the work area by the operator reaches the work allowable time among the component replenishment target devices whose progress state of the component replenishment work is work not performed.
