Self-locking Trim Ring for Lens Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp assembly techniques require multiple component parts, increasing manufacturing costs and labor time, and are not easily adaptable for both wet and dry assembly methods, leading to higher assembly errors.
Innovation Solution
A self-locking trim ring with a plurality of teeth is used to securely attach an optical lens to a heat sink, eliminating the need for additional parts by engaging with a recess in the heat sink, allowing for both dry and wet assembly without separate components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple component parts are used to secure the optical lens, then the assembly can be securely attached, but the manufacturing cost and labor time increase
Solution Approach 1:
The patent combines multiple separate components (trim ring, lens securing mechanism, and locking features) into a single integrated self-locking trim ring assembly. This consolidation maintains secure attachment of the optical lens while reducing the number of parts that need to be handled and assembled, thereby improving assembly efficiency and reducing labor time.
Solution Approach 2:
The self-locking trim ring serves multiple functions simultaneously: it provides structural support, secures the optical lens, provides decorative finish, and includes self-locking features to prevent loosening. This multi-functionality eliminates the need for separate components for each function, reducing manufacturing cost and assembly complexity while maintaining secure attachment.

3Strength
If existing assembly techniques are used, then the optical lens can be secured to the heat sink, but the assembly process requires additional steps that increase assembly errors
Solution Approach 1:
The self-locking trim ring features self-aligning and self-locking mechanisms that automatically ensure proper positioning and secure attachment of the optical lens. The engagement features and recesses guide the assembly process, eliminating the need for multiple manual adjustment steps and reducing the likelihood of assembly errors, thereby improving assembly accuracy and reliability.
4Ease of manufacture
If existing heat sink and lamp assemblies are designed for specific assembly techniques, then the assembly process is simplified, but the design is not adaptable for both wet and dry assembly techniques
Solution Approach 1:
The self-locking trim ring and heat sink assembly are designed with universal engagement features that work effectively with both wet assembly (using adhesive) and dry assembly (mechanical fastening only) techniques. The recesses and engagement features provide structural securing in both methods, allowing the same design to be adapted to different assembly preferences or requirements without modification.

AI summary
A lamp comprises an optical lens. The lamp further comprises a self-locking trim ring including a plurality of teeth. The self-locking trim ring is disposed over the optical lens. The lamp further comprises a heat sink. The heat sink has an inner chamber wherein the optical lens is disposed in the inner chamber. The heat sink also has an outer chamber disposed radially outwardly from the inner chamber. The outer chamber has a recess that engages the plurality of teeth. The self-locking trim ring secures the optical lens to the heat sink.
