Solution Overview

Problem

Existing inspection methods for objects on a transfer rail are costly due to the need for multiple camera devices and are inefficient in terms of space and time, especially when inspecting all surfaces of an object.

Innovation Solution

A flipper apparatus with Y-axis and X-axis flipper units and a Z-axis elevation unit, allowing for the rotation and positioning of objects at multiple angles for inspection using a single camera device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple camera devices are used to inspect top and side surfaces of objects on a transfer rail, then inspection coverage is improved, but apparatus cost increases substantially

Engineering Contradiction:
Improveinspection coverageVSAvoidapparatus cost
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single camera device is made multi-functional by implementing a rotating mechanism that allows it to inspect multiple surfaces (top, side, front, rear) of objects. The camera rotates about the Y-axis to inspect different surfaces sequentially, replacing what would traditionally require multiple fixed camera devices positioned at different locations.

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

Solution Approach 2:

The camera device is transformed from a static inspection tool to a dynamic one by adding rotation capability. The camera can rotate about the Y-axis to change its inspection angle and orientation, enabling it to capture images of multiple surfaces that would otherwise require multiple fixed cameras positioned at different angular locations.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If conventional turn-over apparatus is used to inspect all surfaces of objects, then inspection completeness is improved, but space efficiency decreases and inspection time increases

Engineering Contradiction:
Improveinspection completenessVSAvoidinspection time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The single camera device performs multiple inspection functions (top surface, side surfaces, front surface, rear surface) that would traditionally require separate inspection stations or turn-over apparatus. By integrating rotation capability, one camera replaces what would otherwise require multiple cameras and complex turn-over mechanisms.

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

Solution Approach 2:

The inspection system adds rotational dimensionality to the camera's operation. Instead of moving objects through multiple fixed inspection stations in linear space, the camera rotates about the Y-axis to access different surfaces, effectively using angular rotation as an additional dimension for inspection coverage.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
