Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection lamps with a rolling structure require high processing and installation accuracy due to the coaxial arrangement of the rotating shaft and connecting rod, making them difficult to assemble and inflexible in use.
Innovation Solution
A projection lamp design featuring a light condensing ball lens with a single-point connection to the outer housing via a shaft sleeve and motor-driven rotation, simplifying the mounting structure and reducing accuracy requirements through a gear and bearing system that allows synchronous rotation and stable support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rotating shaft and connecting rod portion are installed at the housing at the same time with coaxial arrangement, then the projection lamp can project movable light with gorgeous light effect, but the processing accuracy and installation accuracy requirements become extremely high, resulting in difficult processing and installation
Solution Approach 1:
The patent divides the connection structure into separate components: the connecting rod portion is connected to the housing, while the rotating shaft connects to the light condensing ball lens independently. This segmentation allows each component to be processed and installed separately, reducing the overall accuracy requirements while maintaining the functional integrity of the rolling light effect.
Solution Approach 2:
The patent extracts the rotating shaft connection from the housing structure, allowing it to rotate independently within the light condensing ball lens. This extraction enables the rotating shaft to be connected separately rather than requiring simultaneous coaxial alignment with the housing, significantly reducing installation complexity and accuracy requirements.
2Stability of the object's composition
If the light condensing ball lens has two points connected to the housing through coaxial arrangement, then the structure appears stable, but the processing and installation become difficult due to high accuracy requirements
Solution Approach 1:
The patent segments the connection points: one connecting rod portion remains connected to the housing for stability, while the rotating shaft connection is separated and allowed to rotate independently. This segmentation maintains structural stability through the fixed connecting rod while simplifying manufacturing through the independent, easily-installable rotating shaft assembly.
Solution Approach 2:
The patent changes the connection parameter from fixed coaxial alignment to independent rotational connection. The rotating shaft can rotate within a certain range without requiring precise coaxial alignment with the housing, changing the structural parameter from rigid fixed-position connection to flexible rotational connection, thereby improving ease of manufacture.
3Reliability
If coaxial arrangement is used for rotating shaft and connecting rod, then the rolling lamp effect can be achieved, but the structure becomes inflexible in use due to high accuracy requirements
Solution Approach 1:
The patent introduces dynamic rotation capability to the rotating shaft, allowing it to rotate independently within the light condensing ball lens. This dynamic feature enables the rolling lamp effect while providing usage flexibility, as the rotating shaft can adapt to different rotational positions without requiring precise fixed alignment, thereby improving adaptability.
Solution Approach 2:
The patent extracts the rotation function from the fixed coaxial structure, allowing the rotating shaft to operate independently. This extraction provides usage flexibility by enabling the rotating shaft to move freely within its rotational range without being constrained by strict coaxial alignment requirements, while still achieving the desired rolling lamp effect.
