Flying Insect Trap With Islands-In-Sea Color Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flying insect traps face issues such as liquid spillage, ineffective catching mechanisms, difficulty in assembly, and insufficient understanding of color combinations for attracting insects, leading to inefficient trapping performance.
Innovation Solution
A flying insect trap featuring a sticky sheet with an islands-in-sea pattern in specific color combinations (Hue No. 4-5 for the background and Hue No. 7-9 for island-like portions) on a main part covered by a hinged cover part, with multiple entrances and a support structure to ensure easy assembly and effective insect attraction and catching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid attracting agents and catching agents are used, then the trap can attract and catch insects, but the liquid is likely to spill or leak
Solution Approach 1:
The patent uses a flexible adhesive sheet as the catching agent carrier instead of liquid catching agents. The sheet can be conformally attached to the inner surface of the container, providing a stable, non-spilling surface that maintains insect-catching effectiveness while eliminating liquid leakage problems.
Solution Approach 2:
The patent changes the physical state of the catching agent from liquid to solid (adhesive sheet), and modifies the attracting agent delivery system to control evaporation rates and concentration gradients, thereby maintaining attraction effectiveness while preventing spillage.
2Reliability
If fat and oil are used as catching agents, then insects can be suffocated to death, but the agents are not inherently insecticidal and insects may survive
Solution Approach 1:
The patent converts the harmful sticky residue left by fat and oil into a beneficial trapping mechanism by using a specially formulated adhesive sheet. This sheet provides reliable sticking power to capture insects while incorporating insecticidal properties to ensure mortality, transforming the partial effectiveness of traditional agents into a complete solution.
Solution Approach 2:
The adhesive sheet combines multiple functional materials: adhesive substances for sticking, insecticidal components for killing, and potentially UV-reactive materials for enhanced attraction. This composite structure integrates the benefits of traditional agents while eliminating their shortcomings.
3Device complexity
If the support member and base are almost entirely exposed, then the trap structure is simple, but flying insect pests can easily avoid being caught
Solution Approach 1:
The patent divides the container into distinct functional segments: an attracting agent holding portion, an adhesive sheet portion, and a cover portion with controlled openings. This segmentation allows each component to perform its function optimally while working together to prevent insect escape.
Solution Approach 2:
The patent introduces a vertical dimension by adding a cover portion that extends over the base, creating a three-dimensional trapping space. The controlled openings in the cover restrict insect movement paths, forcing them to pass through the adhesive zone, thereby increasing catching reliability without significantly complicating the overall structure.
4Productivity
If large-area openings are provided for insect attraction, then insects can be attracted into the trap, but insects can easily escape from the trap
Solution Approach 1:
The patent creates a dynamic trapping system where the cover portion can be positioned to control opening size. During attraction, larger openings allow efficient insect entry; during containment, the cover is positioned to minimize openings, preventing escape while maintaining the adhesive sheet's effectiveness.
Solution Approach 2:
The adhesive sheet is pre-positioned on the inner surface of the container before insects enter. This preliminary placement ensures that insects are immediately captured upon entry through the openings, preventing escape even when openings are relatively large during the attraction phase.

AI summary
A flying insect trap is provided which utilizes a combination of colors that is highly attractive to flying insects and thereby achieving high attracting performance and catching performance. The flying insect trap includes a sticky sheet 30 which sticks to the flying insect, a main part 10 on which the sticky sheet 30 is placed, a cover part 20 which is attached to cover the sticky sheet 30, and an entrance 40 provided in the cover part 20, through which the flying insect enters. When the cover part 20 is attached to the main part 10, an internal space S which accommodates the sticky sheet 30 is formed between the main part 10 and the cover part 20. The internal space S is in communication with an external environment infested with the flying insect through the entrance 40. The sticky sheet 30 has an islands-in-sea pattern including a background region P having a color of Hue No. n1 [n1: 4 (reddish orange) - 6 (yellowish orange)] of the PCCS color wheel and a plurality of island-like portions Q having a color of Hue No. (n2 + 2) - (n2 + 4) [n2 ← n1: 6 (yellowish orange) - 10 (yellow-green)] of the PCCS color wheel.
