Solution Overview

Problem

Current manual application of mold-stripping agents to large surfaces is time-consuming and lacks repeatability due to operator dependence and uneven distribution.

Innovation Solution

A system comprising a frame on a locomotive system with a tank and application head, equipped with ejection nozzles and a guiding system for obstacle detection, allowing precise and repeatable application of a fluid product, including a cloth for soaking or projecting the agent.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual application by operator is used, then flexibility and adaptability are maintained, but application time increases and repeatability decreases

Engineering Contradiction:
ImproveflexibilityVSAvoidapplication time
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The application system is equipped with obstacle detection means that autonomously detect and respond to obstacles without requiring manual intervention. The system self-adjusts its operation based on detected obstacles, maintaining flexibility while eliminating the time cost of manual decision-making and adjustment.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If manual application by operator is used, then adaptability to obstacles is maintained, but application repeatability and consistency deteriorate

Engineering Contradiction:
Improveadaptability to obstaclesVSAvoidapplication repeatability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system incorporates obstacle detection means that provide real-time feedback about the application environment. This feedback loop enables the system to consistently adapt to obstacles while maintaining repeatable application quality, as the detection system objectively measures and responds to conditions rather than relying on variable human judgment.

Inventive Principle:
Principle #23Feedback

3Device complexity

If manual application with cloth soaking is used, then simple device structure is maintained, but fluid distribution uniformity deteriorates

Engineering Contradiction:
Improvestructure simplicityVSAvoidfluid distribution uniformity
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The system replaces the manual mechanical action of soaking and applying fluid with a controlled fluid delivery system. The application head with supply nozzle provides uniform fluid distribution through controlled flow, eliminating the uneven soaking characteristics of manual cloth application while maintaining operational simplicity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If automated application system is implemented, then application repeatability and precision are improved, but device complexity increases

Engineering Contradiction:
Improveapplication repeatabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The application system is divided into distinct functional modules: a locomotive system for movement, a tank for fluid storage, an application head with supply nozzle for fluid delivery, and obstacle detection means for environmental sensing. This segmentation allows each component to perform its function independently and reliably, improving overall system repeatability while keeping individual components relatively simple.

Inventive Principle:
Principle #1Segmentation

AI summary

An application system for depositing a fluid product on a surface. The application system comprises a frame mounted on a locomotive system ensuring the displacement of the frame over the surface, a tank mounted on the frame and receiving the fluid product to be applied, and an application head fluidically connected with the tank via a supply nozzle. The application system comprises a guiding system which comprises detectors to detect the obstacles in the environment of the application system. Such an application system allows for an even application of the fluid product over the entire surface.
