Lens Module Outer Pillars UV Glue Solidification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lens modules fixed to substrates using UV glue experience unstable adhesion due to incomplete solidification of UV glue within the containing cavity, as ultraviolet light cannot penetrate to irradiate the glue in this area.
Innovation Solution
The lens module design features a lens holder with outer pillars spaced from inner walls, allowing UV glue to be applied at the bottom of these pillars, enabling ultraviolet light to pass through the gaps and fully solidify the glue, ensuring stable fixation to the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If UV glue is distributed around the lens holder to fix the lens module to the substrate, then adhesion strength is improved, but complete solidification of UV glue cannot be achieved because ultraviolet light cannot penetrate into the containing cavity
Solution Approach 1:
The lens holder is segmented into inner walls forming a containing cavity and outer pillars spaced apart to create gaps. This segmentation allows UV light to pass through the gaps and irradiate UV glue both at the bottom and within the containing cavity, ensuring complete solidification while maintaining adhesion strength.
Solution Approach 2:
The structure transitions from a solid lens holder to one with localized gaps between outer pillars. This local structural modification enables selective UV light penetration in specific areas (through the gaps) while maintaining the containing cavity function, allowing differentiated solidification of UV glue in different regions.
2Adaptability or versatility
If the lens holder is designed with a containing cavity to hold components, then component containment is improved, but UV light penetration is blocked preventing glue solidification
Solution Approach 1:
The lens holder is divided into inner walls that form the containing cavity and outer pillars that create light-passing gaps. This segmentation maintains the cavity's component containment function while introducing pathways for UV light penetration to enable complete glue solidification.
Solution Approach 2:
The gaps between outer pillars serve as intermediary pathways that allow UV light to penetrate through the lens holder structure. These gaps act as mediators between the light source and the UV glue within the containing cavity, enabling solidification without compromising the cavity's containment function.
3Reliability
If outer pillars are added to the lens holder structure to enable UV light penetration, then glue solidification is improved, but device complexity increases
Solution Approach 1:
The outer pillars are integrated directly into the lens holder structure, merging the light-transmission function with the existing structural component. This consolidation avoids adding separate elements and reduces overall device complexity while achieving complete UV glue solidification.
Solution Approach 2:
The outer pillars serve multiple functions: they provide structural support for the lens holder, create gaps for UV light penetration, and define the boundaries of the containing cavity. This multi-functionality reduces the need for additional components, simplifying the overall device structure.

AI summary
A lens module for being fixed to a substrate by UV glues includes a lens barrel and a lens holder integratedly formed at a bottom of the lens barrel. The lens barrel has a hollow receiving groove for receiving an optical lens therein. The lens holder defines a containing cavity communicating with the receiving groove and penetrating through a bottom thereof to form a plurality of inner walls surrounding the containing cavity. The lens holder further defines a plurality of outer pillars spaced from each other and arranged apart from outer peripheries of the corresponding inner walls to define gaps therebetween. The UV glues are distributed to a bottom of each outer pillar so that ultraviolet lights can pass through the intervals between the outer pillars to adequately irradiate and solidify the UV glues for making the lens module fixed to the substrate firmly.
