Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical wild bird and animal repellent devices face issues with deformation, high production costs, and operational failures due to external factors like rain, dust, and rodent damage, as well as labor-intensive and error-prone mounting processes, which affect the reliability and longevity of the chassis.
Innovation Solution
A chassis for mechanical wild bird and animal repellent devices produced from composite plastic using injection molding, integrating key components like a bush, trigger pin, and blower bowl bearing into a single, standardized unit, reducing the need for multiple assembly steps and enhancing durability with a raincoat for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional multi-stage metal chassis production process is used, then structural strength is achieved, but production cost increases and manufacturing precision decreases due to multiple assembly steps and alignment requirements
Solution Approach 1:
The patent combines multiple separate metal components (chassis body, mounting plates, bearing supports, connection elements) into a single integrated plastic chassis housing produced by injection molding. This merging eliminates the need for multiple assembly steps, alignment operations, and fastening procedures, directly resolving the contradiction between manufacturing precision and production process complexity.
Solution Approach 2:
The plastic chassis housing serves multiple functions simultaneously: it provides structural support, acts as a mounting platform for bearings and mechanical components, offers protection against environmental factors, and integrates connection points for assembly. This multi-functionality replaces several separate metal components, reducing both production complexity and improving mounting precision.
2Productivity
If metal chassis with multiple assembly steps is used, then structural strength is achieved, but production time increases and productivity decreases
Solution Approach 1:
The plastic chassis housing is produced as a complete, pre-formed component with all mounting features, bearing supports, and connection points integrated during the injection molding process. This preliminary action eliminates the need for subsequent assembly steps, directly increasing productivity and reducing assembly time.
Solution Approach 2:
By merging multiple metal components into a single plastic housing produced in one manufacturing process, the patent eliminates sequential assembly operations. The single-shot injection molding process produces the complete chassis in one cycle, dramatically improving production efficiency and reducing time loss.
3Reliability
If metal chassis exposed to external factors is used, then mechanical strength is maintained, but reliability decreases due to corrosion and environmental damage
Solution Approach 1:
The patent changes the material parameter from metal to plastic, fundamentally altering the chemical and physical properties of the chassis. Plastic materials are inherently resistant to corrosion, rust, and electrochemical degradation, providing reliable operation in humid, rainy, and dusty environments without the protective coatings required by metal.
Solution Approach 2:
The use of plastic (potentially composite plastic materials) provides inherent resistance to environmental factors such as moisture, rust, and corrosion. This material substitution eliminates the reliability issues associated with metal chassis exposed to external factors while maintaining structural integrity.
4Ease of manufacture
If standardized plastic chassis produced by injection molding is used, then production cost decreases and manufacturing precision improves, but structural strength may be compromised
Solution Approach 1:
The patent employs plastic materials (potentially reinforced or composite plastics) that provide sufficient structural strength for the chassis application while enabling injection molding production. The material selection balances ease of manufacture through molding with the required mechanical strength to support the bird repeller mechanism.
Solution Approach 2:
By changing from metal to plastic materials, the patent alters the strength-to-manufacturing-ease ratio. While plastic has lower absolute strength than metal, it provides adequate strength for the application and enables complex geometries, integrated features, and high-precision mounting surfaces through injection molding, improving overall manufacturing ease.
