Solution Overview

Problem

Manual handling of substrates during picking and placing leads to unsteady movements and increased risk of damage or defects due to human error and prolonged handling times.

Innovation Solution

An apparatus with vertically disposed guide rods and a telescopic picking and placing device driven by a motorized system, which ensures smooth and steady movement of substrates by sliding along the guide rods, reducing manual handling and minimizing substrate movement during picking and placing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual handling is used to pick and place substrates, then ease of operation is improved, but substrate stability deteriorates leading to cracks and defects

Engineering Contradiction:

Improveease of operationVSAvoidsubstrate stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent replaces manual mechanical handling with an automated picking and placing device that uses a suction cup to hold the substrate. The device is mounted on a moving platform that can transport the substrate between cabinet and detection position, eliminating hand movements and associated instability while maintaining operational ease through automated control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary picking and placing device between the operator and the substrate. This device acts as a mediator that grasps the substrate with a suction cup and transports it, preventing direct contact and hand movements that cause substrate instability, while still allowing the operator to control the process easily.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If prolonged manual handling is performed, then productivity is reduced due to handling time, but substrate damage increases due to accumulated hand movements

Engineering Contradiction:

ImproveproductivityVSAvoidsubstrate damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The automated picking and placing device replaces prolonged manual handling, eliminating the accumulation of hand movements that cause substrate damage. The device can quickly transport substrates between positions without the fatigue and instability associated with extended manual operation, thereby improving productivity while reducing damage.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses a suction cup that applies sufficient holding force to completely secure the substrate during transport, preventing any movement that could lead to damage. This excessive securing action ensures the substrate remains stable even during rapid automated operations, reducing damage while improving throughput.

Inventive Principle:

Principle #16Partial or excessive action

3Stability of the object's composition

If automated picking and placing device is implemented, then substrate stability is improved, but device complexity increases

Engineering Contradiction:

Improvesubstrate stabilityVSAvoiddevice complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The picking and placing device is segmented into distinct functional components: a moving platform for transportation, a suction cup for grasping, and a support structure. This segmentation allows each component to perform its specific function efficiently while maintaining overall substrate stability, without requiring an overly complex integrated system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The picking and placing device is designed with multi-functionality, serving as both a transport mechanism and a holding device. The suction cup provides both grasping and stabilization functions, while the moving platform handles both positioning and transfer operations, reducing the need for additional specialized components and simplifying the overall system.

Inventive Principle:

Principle #6Universality (Multi-functionality)
