Solution Overview
Problem
Existing downlights lack the ability to adjust depth of anti-glare, illumination angle, and light-emitting angle, leading to increased mold investment and storage costs due to the need for various models with different functions.
Innovation Solution
A downlight design featuring a cylindrical body with a rotatable disk and connecting member, allowing for adjustments in anti-glare depth, illumination angle, and light-emitting angle through friction pivots and damping mechanisms, along with a heat sink and rotating lens system for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If downlights are designed with fixed functions (non-adjustable anti-glare depth, illumination angle, and light-emitting angle), then manufacturing and storage costs increase due to the need for multiple models, but structural simplicity is maintained
Solution Approach 1:
The patent implements a universal adjustable structure where a single downlight model can perform multiple functions by adjusting the lamp body position and rotation angle. The lamp body can be moved vertically to adjust anti-glare depth and rotated to change illumination and light-emitting angles, replacing the need for multiple fixed-function models.
Solution Approach 2:
The patent transforms fixed structural elements into dynamic adjustable components. The lamp body is designed to be movable vertically and rotatable, allowing users to dynamically adjust the anti-glare depth, illumination angle, and light-emitting angle according to different usage scenarios.
2Adaptability or versatility
If adjustable mechanisms are added to enable multi-functionality, then versatility improves, but manufacturing precision requirements increase due to friction pivots and damping mechanisms
Solution Approach 1:
The patent introduces damping mechanisms as intermediary elements between the adjustable lamp body and the fixed housing. These damping mechanisms facilitate smooth adjustment while maintaining stable positioning, reducing the precision requirements for direct connections between moving and stationary parts.
Solution Approach 2:
The damping mechanisms provide friction-based feedback that helps users sense and control the adjustment process. This feedback mechanism allows for precise positioning without requiring extremely tight manufacturing tolerances, as the damping effect compensates for minor variations in component dimensions.
3Adaptability or versatility
If multiple fixed-function downlight models are produced, then functional requirements are met, but storage costs and mold investment increase
Solution Approach 1:
The patent creates a universal downlight model that can replace multiple specialized models. By enabling vertical movement and rotation of the lamp body, a single model design can provide various lighting configurations (different anti-glare depths, illumination angles, and light-emitting angles), eliminating the need to manufacture and store multiple fixed-function models.
