Solution Overview

Problem

Existing systems for joining electronic assemblies and manufacturing workpieces are not fully automated, leading to manual interventions that can cause errors and disrupt the formation of clean rooms, particularly ISO 5 clean rooms, which are essential for semiconductor manufacturing.

Innovation Solution

A system comprising multiple modules for loading, production, and unloading stations, with a multiple gripper for simultaneous handling of electronic assemblies and workpieces, allowing automated movement through a continuous process without manual intervention, creating a clean room environment suitable for microelectronics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual intervention is used for transferring workpieces and covering with process covers, then the system is easier to operate and set up, but the formation of clean room environment cannot be ensured and errors may occur

Engineering Contradiction:
Improvemanual operationVSAvoidparticle contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system is divided into multiple sealed modules (loading module, processing module, unloading module) that can be independently maintained. This segmentation allows each module to be kept at appropriate pressure differentials and cleanliness levels, with automated transfer mechanisms that maintain seal integrity during workpiece movement between modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Manual mechanical operations are replaced with automated robotic systems including robotic arms for workpiece handling, automated cover application mechanisms, and sealed transfer chambers. These automated systems operate within controlled environments, eliminating the need for personnel to enter clean room areas and thus preventing particle contamination.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If manual steps are interrupted between individual positions, then the system is simpler to design, but continuous clean room formation is disrupted

Engineering Contradiction:
Improvesystem designVSAvoidclean room continuity
Core Design Contradiction:
Device complexityVSDuration of action of stationary object

Solution Approach 1:

The system employs continuous automated processes where workpieces are transferred through sealed modules without breaking the clean room environment. Automated conveyors and robotic transfer mechanisms maintain continuous operation, eliminating interruptions that would require clean room conditions to be broken and re-established.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Multiple processing functions are nested within sealed modular chambers that maintain clean room conditions. Each module contains its own controlled environment, and automated transfer mechanisms move workpieces between nested modules without exposing them to external contamination, maintaining continuous clean room formation throughout the entire process.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If fully automated system with multiple modules is implemented, then clean room formation is ensured and productivity increases, but device complexity increases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automated modules are designed with universal interfaces and standardized configurations that can handle multiple workpiece types and processing operations. This multi-functionality reduces the number of specialized components needed, simplifying the overall system architecture while maintaining high productivity through automated continuous operation.

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

4Manufacturing precision

If multiple gripper with alignment function is used, then manufacturing precision improves, but device complexity increases

Engineering Contradiction:
Improveworkpiece alignmentVSAvoidgripper mechanism
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The multiple gripper system incorporates self-aligning features where the gripper fingers or clamps automatically adjust to workpiece dimensions and positions. Sensors and feedback mechanisms enable the gripper to self-correct alignment deviations, achieving precise workpiece positioning without requiring complex external alignment apparatus or manual intervention.

Inventive Principle:
Principle #25Self-service
