Solution Overview

Problem

The increasing demand for small quantity production of multiple types of products leads to a rise in production switches, resulting in prolonged setup changeover times and reduced productivity due to the need to adjust the arrangement pattern and quantity of backup pins on a backup plate for each production switch.

Innovation Solution

The component mounting method divides backup members into multiple arrangement areas on the backup plate, allowing for reduced setup changeover frequency and automation of the process, utilizing a stocker and chuck mechanism to efficiently arrange backup members during idle time, and adjusting conveyor width to accommodate different board widths, thereby shortening total setup changeover time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If setup changeover is performed manually or automatically for each production switch, then the backup pin arrangement can be adjusted according to different circuit board types, but the total setup changeover time increases and productivity decreases

Engineering Contradiction:
Improvebackup pin arrangement adaptabilityVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The backup plate is divided into multiple arrangement areas, each capable of independently holding different backup pin configurations. This segmentation allows different circuit board types to be supported by selecting specific arrangement areas without requiring complete reconfiguration, thereby reducing setup changeover time while maintaining adaptability to various board types and sizes

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple arrangement areas are prepared in advance with different backup pin configurations. When a production switch occurs, the system can quickly switch between pre-prepared arrangements rather than performing manual reconfiguration, thus maintaining versatility while significantly reducing setup time and improving productivity

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the number of production switches increases to meet demand for multiple product types, then product variety is satisfied, but total setup changeover time increases and operating rate decreases

Engineering Contradiction:
Improveproduct type flexibilityVSAvoidsetup changeover time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The backup plate with multiple arrangement areas serves multiple functions by accommodating different circuit board types, sizes, and configurations within a single unified structure. This multi-functionality allows the system to handle diverse product types without requiring separate backup plates for each product, thereby reducing setup time while maintaining product flexibility

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables dynamic selection and switching between different arrangement areas on the backup plate based on production requirements. This dynamic capability allows rapid adaptation to different product types without physical reconfiguration, reducing setup changeover time while maintaining the ability to produce multiple product types

Inventive Principle:
Principle #15Dynamics
