Solution Overview
Problem
Current bird-repellent coating materials are ineffective due to issues with durability, environmental contamination, and toxicity, and existing solutions like nets and sound-based repellents have limitations in installation location and maintenance requirements.
Innovation Solution
A bird-repellent coating material incorporating microencapsulated visual and olfactory repellents, such as ultraviolet reflecting agents and sulfur-containing terpenoids, into an aqueous resin vehicle, with colloidal silica for enhanced durability and safety, allowing for sustained repellent effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional repellent coating materials (solvent-based, fragrance-based, plasticizer-based, amine-based, fierce animal excreta-based) are used, then bird repellent effect is achieved, but durability of effects is poor and environmental contamination occurs due to volatility
Solution Approach 1:
The patent changes the chemical parameters of the repellent coating by using water-soluble organic compounds with specific molecular weight ranges (50-500 Daltons) and incorporating them into a water-based resin system. This parameter change eliminates the volatility issues of conventional solvents while maintaining repellent effectiveness, thereby improving durability and reducing environmental contamination.
Solution Approach 2:
The patent creates a composite coating material by combining water-based resin with water-soluble organic repellent compounds. This composite structure allows the coating to maintain its integrity and repellent properties over time without the harmful volatility of conventional solvent-based systems, resolving the contradiction between durability and environmental contamination.
2Reliability
If toxic repellents such as agrichemicals are formulated into coating material, then strong bird repellent effect is achieved, but safety and environmental friendliness deteriorate
Solution Approach 1:
The patent converts potentially harmful substances into safe repellents by using water-soluble organic compounds that occur naturally or can be synthesized without toxic residues. These compounds provide strong repellent effects while being environmentally benign, thus converting the need for strong repellency into an opportunity to use safe, water-based materials.
Solution Approach 2:
The patent employs biodegradable water-soluble organic compounds that can break down naturally after serving their repellent function. This approach ensures that while the repellent effect is strong and reliable during the coating's service life, the material does not persist as a toxic substance in the environment, thereby maintaining both reliability and safety.
3Reliability
If capsaicin and/or lanolic acid ester are used as repellents, then effectiveness is achieved when birds ingest the coating film, but effectiveness in preventing birds from coming is poor
Solution Approach 1:
The patent replaces the ingestion-based repellent mechanism (mechanical/taste-based) with a volatile aroma-based mechanism (olfactory). By using water-soluble organic compounds that emit repellent aromas, the coating prevents birds from approaching in the first place, rather than only working after ingestion. This substitution of mechanism resolves the contradiction between ingestion effectiveness and preventive effectiveness.

AI summary
Various measures have conventionally been adopted against bird damage, but as yet none has proved decisive. There is moreover no technology that affords sustained repellency of coating materials against bird damage. A bird-repellent coating material according to the present invention contains at least one component selected from the group consisting of a microencapsulated aqueous dispersion of a visual repellent against birds, a microencapsulated volatile olfactory repellent against birds and a powder of a visual repellent against birds, and an aqueous resin vehicle that contains the above component. No bird-repellent coating material has been conventionally produced in which the components and so forth of the material are established taking into consideration the diversity and learning ability of birds. The formulation of the bird-repellent coating material according to the present invention, by contrast, has been devised taking into account the senses of sight and smell in birds.
