Solution Overview

Problem

The contamination of internal optical components during the dismantling of the cover in optical transceiving box bodies due to metal particles from mechanical grinding, leading to unusable and analysis-impacted materials.

Innovation Solution

An optical transceiving box body design with a protective cover and limiting structure, where the protective cover is fixedly connected to the housing through a limiting ring and step portion, allowing the closing cover to be removed first, followed by the protective cover, preventing debris from falling on the components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cover is welded to the housing for airtight sealing, then the protection against environmental factors is improved, but the risk of contamination during dismantling increases

Engineering Contradiction:

Improveprotection against environmental factorsVSAvoidcontamination of optical components

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cover is divided into two separate parts: a closing cover that seals the opening and a protective cover that protects the optical components. This segmentation allows the closing cover to be removed for dismantling while the protective cover remains in place, preventing contamination of the optical components during the dismantling process.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The protective cover acts as an intermediary barrier between the closing cover and the optical components. When the closing cover is removed during dismantling, the protective cover prevents metal particles and debris from directly contacting and contaminating the optical components inside the housing.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If mechanical grinding is used to remove the cover, then the dismantling process is improved, but the generation of metal particles increases

Engineering Contradiction:

Improvedismantling processVSAvoidmetal particles

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The protective cover is designed to be easily removable without requiring mechanical grinding. By using a simple snap-fit or friction-fit connection, the protective cover can be detached cleanly, converting the potentially harmful mechanical grinding process into a clean, particle-free removal process that protects the optical components.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Measurement precision

If the cover is removed for analysis, then the inspection process is improved, but the contamination risk to optical components increases

Engineering Contradiction:

Improveanalysis resultsVSAvoidcontamination of optical components

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The cover structure is segmented into a closing cover and a protective cover. During analysis, only the closing cover needs to be removed to access the optical components, while the protective cover remains in place to prevent contamination. This allows thorough analysis to be performed without exposing the optical components to contamination risks.

Inventive Principle:

Principle #1Segmentation

AI summary

An optical transceiving box body (100) and an optical module. The optical transceiving box body (100) comprises a housing (10) and a cover body (20); the housing (10) comprises a cavity (101) having an opening (102); the cavity (101) is used for accommodating an optical assembly; the cover body (20) comprises a protective cover (22) and a closing cover (21); the closing cover (21) closes the opening (102); the protective cover (22) is used for separating the optical assembly from the closing cover (21); the housing (10) further comprises a limiting structure; the protective cover (22) is fixedly connected inside the cavity (101) by means of the limiting structure. In a cover detachment process of the optical transceiving box body (100), the closing cover (21) is removed first, and the protective cover (22) is then removed; under the protection of the protective cover (22), powder generated during the detachment of the closure cover (21) does not fall onto the optical assembly, so that the optical assembly is protected from contamination, the optical assembly can be repeatedly used, production costs are saved, and analysis results of the optical assembly are not affected.
