Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing downlight devices are difficult to design with movable structures, making it challenging to adjust light direction and settings easily, as they are typically installed to a cavity or junction box.
Innovation Solution
A lighting apparatus with a fixing unit, a lamp body, and multiple elastic units that allow for adjustable light direction, featuring a rotation shaft and elastic attachments to enable rotation and tilt adjustments, along with a manual switch and reflective layer for light control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If downlight devices are installed to a cavity or junction box, then the installation is stable and secure, but the light direction cannot be adjusted easily
Solution Approach 1:
The patent applies the dynamics principle by incorporating a rotation shaft that enables the lamp body to rotate relative to the base housing, transforming a static downlight fixture into a dynamically adjustable lighting device. This allows the light direction to be changed easily while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent divides the downlight device into distinct functional modules: a base housing for stable installation in the cavity, a lamp body containing the light source, and a rotation shaft connecting them. This segmentation allows each component to be optimized independently - the base housing provides stable installation while the lamp body with rotation shaft provides adjustable lighting.
2Use of energy by moving object
If LED technology is used, then energy consumption is reduced and lifespan is extended, but initial cost and manufacturing complexity increase
Solution Approach 1:
The patent incorporates a reflective layer within the lamp body that serves multiple functions: it redirects light to optimize illumination distribution, enhances the effectiveness of the LED light source, and contributes to the overall aesthetic appearance. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The patent optimizes the structural parameters of the lamp body and base housing to achieve efficient light distribution and heat dissipation for LED components. By carefully designing the geometry and material properties, the system maximizes LED performance while managing manufacturing considerations.
