Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flying objects with high volume ratio balloons experience instability due to external disturbances like wind, leading to increased time for maintaining flight and posture stability, which affects working efficiency in painting applications.
Innovation Solution
A flying object with multiple blades and a nozzle system that includes a paint ejection mechanism and a fluid ejection mechanism, where the angle between these mechanisms can be adjusted to stabilize flight and ensure high-quality painting, allowing for non-contact painting of surfaces without the need for scaffolding or expensive robots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a high volume ratio balloon is used in the flying object, then the flying object can achieve flight capability, but flight stability is significantly affected by external disturbances such as wind
Solution Approach 1:
The patent applies counterweight principle by adding weight to the lower portion of the flying object body to balance the high-volume balloon's buoyancy. This creates a stable center of gravity that resists external disturbances like wind, allowing the flying object to maintain flight stability while utilizing the balloon's lift capability.
Solution Approach 2:
The patent introduces a vertical dimension to stability control by positioning weight in the lower portion rather than distributing it uniformly. This dimensional adjustment of mass distribution creates a pendulum-like stabilizing effect that counteracts horizontal disturbances from wind.
2Reliability
If time is taken to maintain flight and posture stability, then flight stability is improved, but the working time is increased accordingly
Solution Approach 1:
The patent implements preliminary action by pre-configuring the weight distribution in the lower portion before flight operations begin. This preliminary structural arrangement automatically provides stability during flight, eliminating the need for time-consuming active stabilization adjustments and allowing immediate work commencement.
3Extent of automation
If a robot is used for painting, then painting automation is improved, but capital investment is large and facility conforming to explosion-proof specifications is required
Solution Approach 1:
The patent applies self-service principle by enabling the flying object to autonomously perform painting operations through onboard automated spray mechanisms. The system serves itself by integrating propulsion, positioning, and painting functions in a single unit, eliminating the need for external robotic systems and complex facility infrastructure.
Solution Approach 2:
The patent implements multi-functionality by designing the flying object to perform both navigation/positioning and painting operations. This universal design consolidates multiple functions into one device, reducing capital investment compared to separate robotic painting systems and explosion-proof facilities.
