Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual coating of protruding objects with fluid products, such as mastic or paint, on aircraft components is time-consuming, expensive, and difficult to control for reproducibility, especially in hard-to-reach areas, leading to inefficiencies and potential product degradation due to exposure to air.
Innovation Solution
A device comprising a dispensing assembly with a deformable bell and a rotating dispensing head that applies a controlled amount of fluid product to protruding objects, ensuring homogeneous coverage and minimizing exposure to air, while allowing for efficient operation in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual coating with a brush is used, then the operator can apply the fluid product to the protruding object, but the coating is time-consuming and requires special skill and great concentration
Solution Approach 1:
The patent replaces the manual mechanical brushing operation with an automated dispensing system that uses a rotating bell-shaped applicator. The fluid product is delivered through a controlled dispensing mechanism, eliminating the need for manual brush manipulation and operator skill while significantly increasing coating speed and consistency.
Solution Approach 2:
The dispensing device is designed to automatically control the coating process without requiring operator intervention for skill-based decisions. The system self-regulates the fluid delivery and application through its mechanical design, making the operation independent of operator expertise while maintaining high productivity.
2Manufacturing precision
If manual coating is used, then the operator can control the coating process, but the quantity of product deposited is difficult to control in a reproducible manner
Solution Approach 1:
The patent controls coating parameters through the physical design of the dispensing system, specifically the bell geometry, rotation speed, and fluid delivery rate. These parameters are engineered to provide consistent coating thickness without requiring manual adjustment, achieving both precision and productivity simultaneously.
Solution Approach 2:
The system replaces manual coating control with an automated mechanical dispensing mechanism that delivers precise, reproducible quantities of fluid product. The controlled delivery system ensures consistent coating thickness while operating continuously at high speed, eliminating the trade-off between precision and productivity.
3Ease of operation
If the brush is placed in an open container, then the product is easily accessible, but the product quality degrades when the fluid product is sensitive to air
Solution Approach 1:
The patent uses a bell-shaped flexible or rigid shell that encloses the fluid product during dispensing. This shell structure protects the product from air exposure while allowing controlled delivery through the dispensing mechanism, maintaining both product quality and operational ease.
Solution Approach 2:
The dispensing device creates a protected environment for the fluid product, isolating it from air during storage and dispensing. The enclosed bell structure and controlled delivery system prevent air contact with the product, maintaining its quality while keeping it accessible for application.
4Productivity
If the receptacle is located close to the element to be coated, then the coating operation is efficient, but the displacement of the brush towards the container generates losses of productivity due to non-productive movements
Solution Approach 1:
The patent replaces the operator's manual brush movements with an automated dispensing device that can be positioned and oriented mechanically. The rotating bell applicator eliminates the need for repeated brush-to-container movements, achieving high efficiency without operator fatigue or non-productive movements.
Solution Approach 2:
The invention introduces rotational motion as a new dimension to the coating operation. The bell-shaped applicator rotates around the protruding object, delivering coating material from multiple angles in a single continuous motion, thereby eliminating linear back-and-forth movements and significantly improving productivity.
5Adaptability or versatility
If the fixing elements are located in places that are not easily accessible, then the coating must be done manually with frequent brush replacement, but this increases time consumption and cost
Solution Approach 1:
The patent employs a dynamic dispensing system with a rotatable bell applicator that can adapt its orientation and position to reach fixing elements in difficult-to-access locations. The rotational mechanism and flexible positioning allow the device to coat protruding objects from various angles without requiring manual repositioning or brush replacement, reducing time loss while maintaining versatility.
