Solution Overview

Problem

The installation of cameras in air processing devices, such as air-conditioning units, is complicated due to the need for precise alignment and attachment within the casing, which complicates the process.

Innovation Solution

The camera is attached to a detachable inspection cover that opens and closes an inspection hole, allowing for easy positioning and alignment without the need for complex attachment within the casing, using a support that can be adjusted in length and shape to ensure proper alignment of the camera and the object to be imaged.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the camera is directly attached to the casing, then the imaging position can be fixed, but the alignment and attachment operations become complicated

Engineering Contradiction:
Improveimaging position stabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The casing is divided into a main body and a detachable inspection cover. The camera is attached to the inspection cover rather than directly to the main casing body, separating the imaging function from the main structure. This segmentation allows the camera to be positioned reliably when the cover is closed, while simplifying installation since the cover can be detached for easy camera attachment and reattached without complex alignment procedures.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the camera is attached to a detachable component, then the installation becomes easier, but additional components are required

Engineering Contradiction:
Improveinstallation easeVSAvoidcomponent quantity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The inspection cover serves multiple functions: it provides access to the inspection hole for maintenance purposes and simultaneously serves as the mounting platform for the camera. By making the cover universal for both access and imaging support functions, the patent avoids adding separate mounting brackets or support structures, thereby simplifying the overall component list while ease of installation.

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

AI summary

An air processing device includes: a casing (20); a component (45, 51, 66, 130) detachably provided on a body (20a) of the casing (20); and an imaging device (70) that acquires image data of at least one predetermined object (40, 43, 45, 60, 66) to be imaged in the casing (20). The imaging device (70) is supported by the component (45, 51, 66, 130) so as to be located at a position at which the imaging device (70) can image the object (40, 43, 45, 60, 66) to be imaged.
