Lighting Device Modular Optical Attachment Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lighting devices lack the ability to easily replace optical elements of different sizes or types, as they are typically attached using non-detachable methods such as screws, adhesives, or welding, limiting flexibility and adaptability.
Innovation Solution
The lighting device features multiple attachment interfaces of varying dimensions and types, allowing for the selective attachment of optical elements behind the light exit opening, including reflective and refractive optics, enabling easy replacement and position adjustment without tools, using twist-lock, screwing, or bayonet locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components such as screws or adhesives are used to attach optical elements, then the attachment is secure, but the replacement and adjustment of optical elements becomes difficult and time-consuming
Solution Approach 1:
The attachment system is divided into separate components: a mounting structure with attachment interfaces and detachable optical elements. This segmentation allows the optical elements to be easily removed and replaced without affecting the mounting structure, resolving the contradiction between secure attachment and easy replacement.
Solution Approach 2:
The attachment interface is designed to be dynamically changeable, allowing optical elements to be attached, detached, and reattached multiple times. The bayonet-style or screw-style interfaces provide secure attachment when engaged but allow quick release when needed, enabling the system to transition between secure and easily replaceable states.
2Reliability
If non-detachable methods such as welding are used to attach optical elements, then the attachment is very secure, but the flexibility and adaptability to change optical elements is lost
Solution Approach 1:
The system separates the mounting structure from the optical elements, allowing different optical elements to be attached to the same mounting structure through standardized interfaces. This segmentation enables high attachment security while maintaining full adaptability to interchange elements.
Solution Approach 2:
The mounting structure with standardized attachment interfaces serves multiple functions: it can securely hold different types of optical elements (reflectors, lenses, bulbs) and allows easy replacement. The universal interface design enables one mounting structure to accommodate various optical elements, achieving both security and adaptability.
3Device complexity
If a single attachment interface is used, then the device structure is simple, but the ability to accommodate different sizes and types of optical elements is limited
Solution Approach 1:
Multiple attachment interfaces are provided on the mounting structure, each capable of accommodating different sizes and types of optical elements. These interfaces follow a standardized design that maintains structural simplicity while enabling universal compatibility with various optical elements through size variations and configuration differences.
Solution Approach 2:
Different attachment interfaces are designed with specific local characteristics (different sizes, positions, or configurations) to match different optical element requirements. This local differentiation allows the mounting structure to accommodate diverse optical elements while maintaining overall structural simplicity through a standardized interface design pattern.
