Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp designs lack the ability to easily alter light distribution and shape, limiting user flexibility in achieving desired light patterns.
Innovation Solution
A ceiling lamp with multiple plates that can be moved between closed and open positions using a link mechanism and string system, allowing for adjustable light distribution and shape changes from a continuous surface to a more open form, utilizing opaque plates with reflective inner surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the lamp shade shape is amended to alter light distribution, then the light distribution is improved, but the device complexity increases
Solution Approach 1:
The lamp shade is divided into multiple separate plates (first plate, second plate, third plate, fourth plate) that can move independently. This segmentation allows each plate to be positioned separately to achieve desired light distribution patterns while keeping the overall structure relatively simple and modular.
Solution Approach 2:
The plates are made movable between different positions using link mechanisms and strings, transforming the static lamp shade into a dynamic structure. This allows the light distribution to be adjusted by changing the positions of the plates, providing adaptability without requiring a completely complex redesign of the entire lamp structure.
2Adaptability or versatility
If the lamp is designed with movable plates for shape adjustment, then the adaptability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The lamp is constructed from multiple identical or similar plates and link mechanisms that can be manufactured separately and then assembled. This modular approach allows for standardized manufacturing of individual components, making the overall assembly process more manageable despite the complex final structure.
Solution Approach 2:
The link mechanisms are designed to nest within each other when the lamp is in its closed spherical position. The strings and link arms can be stored within the compact form, reducing the manufacturing complexity of handling long flexible components and allowing for more compact packaging during assembly.
3Illumination intensity
If the plates are made opaque with reflective inner surfaces, then the light reflection is improved, but the illumination intensity deteriorates
Solution Approach 1:
The plates have different properties on different sides: the inner surface is made reflective to bounce light around the lamp and direct it outward, while the outer surface is opaque to block light from the outside and maintain the decorative spherical appearance. This local differentiation of material properties optimizes both light reflection and energy efficiency.
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
Enables easy adjustment of light distribution and shape, providing a decorative function in closed form and enhanced light reflection in open form, while maintaining low manufacturing, storage, and transport costs.
Implementation Method 1
The plates are made of an opaque material, having a reflective inner surface. Thereby when the lamp has the position of being in a closed form it will only give a spread weak light. In said closed position the lamp could be said to have only a decorative function. When the lamp is opened up the light will reflect on the inner surfaces of the plates giving a light distribution depending on how much the lamp has been opened.

AI summary
The present invention concerns a lamp (1) having a number of plates (3, 4, 5). The plates (3, 4, 5) are moveable between a position where the plates (3, 4, 5) form a common outer surface and a position where the plates (3, 4, 5) are separated from each other. By means of the plates the shape and appearance of the lamp (1) may be amended between having the form of for instance a closed sphere and a more or less open form. The plates (3, 4, 5) are placed on upper and lower curved arms (17, 26). The curved arms (17, 26) are connected to an upper ring (10) and a lower ring (9). The curved arms (17, 26) are moved by movement of the lower ring (9) towards and away from the upper ring (10).
