Solution Overview

Problem

Existing adhering substance collecting devices face instability in the positional relationship between the inspection object and the ejection opening, leading to inconsistent detachment and collection efficiency.

Innovation Solution

The device incorporates a supporting portion with a protruded rib shape on the upper and lower surfaces of the internal space, maintaining a constant distance between the inspection object and the ejection opening, ensuring stable airflow detachment and collection of adhering substances from both surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the inspection object is freely inserted without positional constraint, then the ease of operation is improved, but the positional relationship between the inspection object and ejection opening becomes unstable, reducing detachment efficiency

Engineering Contradiction:
Improveease of insertionVSAvoidpositional relationship stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A supporting portion with a protruded rib shape is introduced as an intermediary element between the inspection object and the ejection opening. This rib-shaped support structure mediates the interaction by providing a stable reference surface that ensures consistent positioning of the inspection object relative to the ejection opening, thereby resolving the contradiction between ease of insertion and positional stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The supporting portion with the protruded rib shape represents a simple, cost-effective structural feature that is integrated into the device housing. This inexpensive geometric feature provides reliable positioning without requiring complex mechanical constraints or adjustable mechanisms, achieving stable positioning through a simple permanent structure.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If the ejection opening is positioned far from the inspection object, then the stability of positioning is improved, but the detachment efficiency of adhering substances decreases

Engineering Contradiction:
Improvepositioning stabilityVSAvoiddetachment efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The supporting portion with the protruded rib shape introduces a vertical dimension to the positioning system. By creating a height difference through the rib-shaped protrusion, the inspection object is elevated to a specific height that simultaneously achieves stable positioning and optimal distance from the ejection opening, resolving the contradiction between positioning stability and detachment efficiency.

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

3Quantity of substance

If multiple ejection openings are added to cover both surfaces, then the collection completeness is improved, but the device complexity increases

Engineering Contradiction:
Improvecollection completenessVSAvoidstructure complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The ejection system is segmented into multiple ejection openings distributed across different locations and surfaces. This segmentation allows the airflow to be delivered from multiple points simultaneously, ensuring complete coverage of both surfaces of the inspection object and comprehensive collection of adhering substances without requiring a single complex ejection mechanism.

Inventive Principle:
Principle #1Segmentation

AI summary

In order to detach substances stably from an inspection object, an adhering substance collecting device includes: ejection openings (n) configured to eject gas; a housing (B) on which the ejection openings (n) are provided; and supporting portions (H) which are installed on a surface of the housing (B) on which the ejection openings (n) are provided, and have a prescribed height. The supporting portions (H) include protruded portions formed on the housing (B). The supporting portions (H) each have a cuboid shape, and are installed such that a distance therebetween becomes smaller toward a direction of a recovery opening that is configured to collect substances having been detached from an inspection object (C), from the gas.
