Problem
Conventional pendulum painting methods are cumbersome for novices and children, requiring manual plugging of paint holes and limiting the ability to easily change paint colors or adjust the painting path.
Innovation Solution
A pendulum decorating apparatus featuring a base, a tilt tray, an arm, a tether, and a pot that contains decorating material, allowing for controlled release through a discharge opening and enabling the pot to swing and tilt for varied painting patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional container with a hole at the bottom is used for pendulum painting, then the paint can be discharged through the hole, but the user must manually plug the hole with their finger to prevent paint from dripping, which complicates the operation and reduces ease of use
Solution Approach 1:
The system performs the function of plugging the discharge opening automatically through the interaction of the stopper and spring mechanism. When the container is lifted, the stopper is pulled upward by the tether, automatically blocking the discharge opening without requiring user intervention. This self-service mechanism eliminates the need for manual plugging while maintaining control over paint discharge.
Solution Approach 2:
The stopper is pre-positioned to block the discharge opening before painting begins. The spring is pre-loaded to provide the necessary force to keep the stopper in place. This preliminary preparation ensures that the system is ready for immediate use without requiring the user to manually plug the hole during operation.
2Productivity
If multiple paint cans are connected to deposit more than one color at a time, then the productivity increases, but the device complexity and difficulty of operation increase significantly
Solution Approach 1:
The paint supply system is divided into separate chambers, each capable of holding different colors of paint. Each chamber has its own discharge opening and stopper mechanism. This segmentation allows multiple colors to be available simultaneously without requiring complex connections between multiple cans, maintaining simplicity while enabling multi-color painting capability.
Solution Approach 2:
The container is designed to serve multiple functions: it can hold different colors of paint in separate chambers, each color can be independently controlled by its own stopper, and the same basic structure supports all coloring functions. This multi-functionality eliminates the need for separate containers for each color while maintaining operational simplicity.
3Adaptability or versatility
If the user wants to change the flight path of the container, they must grab the swinging container and move it to a new location, which interrupts the painting process and reduces productivity
Solution Approach 1:
The system transitions from a static suspension to a dynamic tilting mechanism. The tray can be tilted during the painting process to change the flight path of the container without requiring the user to stop and reposition the container manually. This dynamic adjustment maintains painting continuity while providing adaptability in pattern creation.
Solution Approach 2:
The tilting mechanism adds a new degree of freedom to the system. Instead of only moving the container horizontally to change the flight path, the tray can be tilted to adjust the angle and trajectory of the container's swing. This dimensional change provides flight path adjustability without interrupting the painting process.
4Productivity
If paint is discharged from a swinging container, then the painting function is achieved, but paint may be deposited on surfaces other than the substrate, creating mess and requiring cleanup
Solution Approach 1:
The excess paint that would otherwise be deposited on surrounding surfaces is extracted and collected by the tilt tray positioned beneath the container. The tray captures and contains the overspray and drips, separating the harmful effect from the substrate and preventing mess while maintaining the swinging painting capability.
Solution Approach 2:
The tilt tray acts as an intermediary between the swinging container and the surrounding environment. It intercepts paint that would otherwise be deposited on unwanted surfaces, serving as a protective barrier that allows continuous painting without creating mess on surrounding areas.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus allows for efficient and controlled decoration with multiple colors, facilitating creative patterns and reducing mess, making it more accessible for users of all skill levels.
Implementation Method 1
The spring is configured to exert a bias force on the stopper to bias the stopper to the closed position
Implementation Method 2
the stopper is configured to move to the open position when the weight of the container and the decorating material in the container is greater than the bias force of the spring
Implementation Method 3
the pot is configured to swing with respect to the arm via the tether while releasing the decorating material

AI summary
A pendulum decorating apparatus having a base, an arm coupled to the base and extending upward from the base, a tether coupled to a portion of the arm above the base, and a pot coupled to the tether. The pot is configured to contain a decorating material, and the pot is configured to swing with respect to the arm via the tether while releasing the decorating material through a discharge opening of the pot. The arm may be coupled to a tilt tray supported by the base with the arm and tilt tray configured to tilt together with respect to the base. The pot may include a container configured to contain the decorating material and a stopper movable to close or open the discharge opening of the pot. The pot may include a plurality of chambers each configured to contain a different color or type of decorating material.
