Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current production optimization devices for component mounting lines require labor-intensive trial and error to find settings that balance investment costs and productivity, especially when the number of components exceeds the user's ownership, limiting efficiency improvements.
Innovation Solution
A production optimization device that compares optimization results under both restricted and unrestricted conditions, displaying total production time, cycle time, and additional investment costs to simplify the search for optimal settings, including the ability to select from various types and quantities of feeders and suction nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of feeders and tape reels is increased beyond what the user currently owns, then productivity and cycle time balance improve, but investment cost increases
Solution Approach 1:
The system dynamically adjusts the selection of feeders and tape reels based on real-time production requirements and existing inventory, rather than requiring fixed ownership of all possible components. This allows the system to optimize productivity by using available resources efficiently while avoiding unnecessary investments in unused equipment.
Solution Approach 2:
The optimization device changes parameters such as feeder assignment, tape reel selection, and mounting machine configuration to achieve optimal productivity within the constraints of existing equipment inventory. By adjusting these parameters rather than increasing equipment quantity, the system improves production efficiency without additional investment.
2Productivity
If trial and error methods are used to find optimal production settings, then appropriate balance between investment cost and productivity can be achieved, but labor time and complexity increase significantly
Solution Approach 1:
The optimization device performs automatic optimization of production settings without requiring manual trial and error by operators. The system self-adjusts feeder assignments, mounting sequences, and resource allocation based on production requirements, eliminating labor-intensive manual optimization while reducing process complexity.
Solution Approach 2:
The system uses feedback from production data and equipment status to automatically adjust and optimize production parameters. By continuously monitoring and adjusting settings based on real-time feedback, the system achieves optimal productivity without manual intervention or complex optimization procedures.
3Quantity of substance
If the selection range of members is restricted to only owned equipment, then investment cost is minimized, but productivity improvement opportunities are lost
Solution Approach 1:
The optimization device enables existing equipment to serve multiple functions and be used in various configurations to meet different production requirements. By maximizing the utilization flexibility of owned equipment, the system captures productivity improvement opportunities without requiring additional specialized equipment for each scenario.

AI summary
In a production optimization device of a component mounting line, an intra present property optimization process of optimizing production of the component mounting line under conditions in which a selection range of members to use in the production is restricted to within a range of members actually owned by a user (present property), and a no-property-restriction optimization process of optimizing the production of the component mounting line under conditions in which restriction of the selection range of the members to use in the production is removed for at least a subset of the members are executed, and optimization results of the intra present property optimization process are displayed on a display device compared to optimization results of the no-property-restriction optimization process. As the intra present property optimization results and the no-property-restriction optimization results, a total production time, a cycle time, a number of set-up changes, and a total set-up changing time are displayed, and further, for the no-property-restriction optimization results, a total production time increase/decrease effect, and names and quantities of members which need to be added to owned members are displayed.
