Solution Overview

Problem

Conventional laser paint film removal apparatuses face complexity in configuration due to the need for shielding members to protect the optical system from flying objects, complicating the laser irradiation portion.

Innovation Solution

A collecting apparatus with a separate collecting case that separates the processing target surface and laser irradiation portion, using transparent panels and a suction device to suck flying objects, maintaining a sealed interior space, and optionally using magnets or gas introduction for fixation and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a shielding member is provided to protect the optical system from flying objects, then the optical system is protected from flying objects, but the configuration of the laser irradiation portion becomes complicated

Engineering Contradiction:
Improveprotection of optical systemVSAvoidconfiguration of laser irradiation portion
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention divides the system into two separate parts: a laser irradiation portion and a collection case. The collection case is positioned to receive flying objects generated during laser processing, separating the protection function from the laser irradiation system itself. This segmentation allows the optical system to remain simple while still providing protection through the dedicated collection case structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protection function is extracted from the laser irradiation portion by introducing a separate collection case. This case is positioned to intercept flying objects before they can reach the optical system, removing the need for complex shielding members within the laser irradiation portion itself

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If a collection case is provided separate from the laser irradiation portion, then the configuration is simplified, but the flying objects may still reach the laser irradiation portion

Engineering Contradiction:
Improveconfiguration of laser irradiation portionVSAvoidflying objects reaching optical system
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The collection case acts as an intermediary structure positioned between the processing target and the laser irradiation portion. It receives and contains flying objects generated during laser processing, preventing them from reaching the optical system. The case includes a suction device that actively removes flying objects, providing an intermediate protective barrier that simplifies the overall configuration while maintaining protection

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In order to avoid the configuration of a laser irradiation portion from becoming complicated because of coping with flying objects generated in surface processing by a laser light, a collecting apparatus for laser processing 20, comprises a collecting case 21 that is formed separate from a laser irradiation portion 32 for irradiating a laser light to a processing target surface 5 and separates the processing target surface 5 and the laser irradiation portion 32 in surface processing on land, the collecting case 21 having an opening portion formed in its one side and being provided with transparent panels 11 and 12 facing the opening portion 13, wherein surface processing becomes possible in which a laser light L is irradiated from the laser irradiation portion 32 to the processing target surface 5 through the transparent panels 11 and 12 when the collecting case 21 is in the installation state that the opening portion 13 is closed and the processing target surface 5 is covered and a suction device 22 for sucking flying objects generated in the surface processing by sucking air inside of the collecting case 21 in the installation state.
