Innovation Solution
A candle-like lighting device featuring a hollow transparent candle shell with a pre-determined texture, a stand with a control circuit and rotating unit, and a non-transparent reflector with a void area, which spins to project dynamic light patterns when powered, enhancing visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electric candle uses a static shell with manufactured textures, then the manufacturing process is simple and cost-effective, but the visual effect is static and monotone without dynamic changes
Solution Approach 1:
The patent applies the dynamics principle by transforming the static shell into a rotatable component. The shell is mounted on a rotating unit that can spin it at variable speeds, converting a static visual display into a dynamic one. This allows the pre-determined textures on the shell to create changing light patterns and visual effects without requiring multiple shells or complex manufacturing processes.
Solution Approach 2:
The patent introduces temporal dimension to the visual effect by adding rotation capability. Instead of only spatial variations in texture, the rotation adds the dimension of time, creating dynamic visual patterns that change continuously. The reflector with void areas further enhances this by projecting moving shadows and light patterns as the shell rotates.
2Adaptability or versatility
If the electric candle adds a rotating unit and reflector with void areas, then the visual effect becomes dynamic with changing light patterns, but the device complexity increases
Solution Approach 1:
The rotating unit serves multiple functions: it rotates the shell to create dynamic visual effects, positions the shell correctly relative to the reflector, and can be controlled to vary rotation speed for different visual patterns. The reflector with void areas also serves dual purposes by both reflecting light and creating projected shadow patterns. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The reflector acts as an intermediary element between the illuminator and the rotating shell. It receives light from the illuminator and projects patterns through its void areas onto the rotating shell, mediating the interaction between the light source and the display surface. This intermediary component enables complex visual effects while keeping the overall structure relatively simple.
3Illumination intensity
If the shell is made transparent with pre-determined textures, then the light transmission and visual effect are enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The textures are pre-determined and formed on the shell during the injection molding process itself, rather than being added as separate post-processing steps. This preliminary action integrates texture creation into the primary manufacturing process, ensuring precision while reducing the need for subsequent manufacturing operations. The transparent material allows these pre-formed textures to effectively modulate light transmission.
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 spinning candle shell and light projection through the reflector's void area create a dynamic visual effect, enhancing the ambiance and mood with changing light patterns.
Implementation Method 1
a light from the illuminator transmits through the void area of the reflector for projecting the shape of the void area on a surface of the spinning candle shell
Implementation Method 2
the rotating unit consists of a gear set as connected with a power unit. The candle shell is positioned on the gear set and thus spins as driven thereby

AI summary
A candle-like lighting device includes a candle shell, a stand and a reflector. The candle shell is positioned above the stand at which the reflector is secured and extends inside the candle shell. A control circuit, an illuminator as surrounded by the reflector and a rotating unit are provided within the stand. The candle shell, spinning as driven y the rotating unit, is provided with a void area. Thereby a light from the illuminator transmits through the void area of the reflector for projecting the shape of the void area on a surface of the spinning candle shell in order to achieve the dynamic visual effect.
