Solution Overview

Problem

Existing insect trapping devices face reduced trapping performance due to insufficient light reach and potential eye strain from attraction light placement, necessitating an improved air blowing device with enhanced insect trapping capabilities.

Innovation Solution

The air blowing device incorporates a dark-colored cover member with suction ports and a bright-colored housing, featuring an insect trapping sheet with an adhesive, positioned to attract and trap insects effectively while minimizing eye strain, with an attraction light source directing light towards the upper portion of the insect trapping space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the attraction light source is mounted on the outer surface of the insect trapping device, then the attraction light can reach farther to attract more insects, but it may exert an adverse effect on the user's eyes

Engineering Contradiction:

Improveinsect trapping performanceVSAvoideye strain from attraction light

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The device is divided into two distinct parts: a housing that emits attraction light to draw insects from a distance, and a separate cover member that traps insects. The housing contains the attraction light source and communicates with the cover member through opening portions, allowing insects to be lured in without exposing users to direct light while maintaining trapping effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The opening portions in the cover member serve as intermediaries between the attraction light source in the housing and the insect trapping space. Insects are attracted through these openings without users being directly exposed to the light source, effectively mediating between the need for long-range attraction and user safety.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the attraction light source is mounted inside the housing, then user safety is improved, but the attraction light reach is insufficient and insect trapping performance decreases

Engineering Contradiction:

Improveeye strain from attraction lightVSAvoidinsect trapping performance

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The device utilizes vertical stacking to create multiple spatial dimensions. The housing is positioned above the cover member with opening portions that extend downward, allowing attraction light to illuminate the trapping area from above without requiring the light source to be externally mounted. This dimensional arrangement maintains both safety and effectiveness.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Productivity

If the cover member is made transparent to allow light passage, then attraction light can reach insects effectively, but the dark color needed for insect attraction is compromised

Engineering Contradiction:

Improveinsect trapping performanceVSAvoidlight reach through cover member

Core Design Contradiction:

ProductivityVSIllumination intensity

Solution Approach 1:

Different parts of the device have different optical properties optimized for their specific functions. The housing is made transparent or translucent to allow attraction light to pass through and illuminate the trapping area, while the cover member is made dark-colored to attract insects and prevent them from escaping. This local differentiation of material properties resolves the contradiction between light transmission and insect attraction.

AI summary

Provided is an air blowing device that makes it possible to safely improve insect trapping performance. The air blowing device 1 is provided with: a housing 2 comprising an inlet 20 and an outlet 5 for air; an air blower 10 arranged within the housing 2; a pre-filter 8 that is arranged in the inlet 20 and that collects dust within air; and a cover member 3 that comprises an air suction port 4, that is attached to the housing 2, and that forms an insect trap space 25 between the suction port 4 and the inlet 20. Insects that enter the insect trap space 25 via the suction port 4 are trapped. The outer surface of the cover member 3 is formed so as to have a dark color.
