Lens Structure Adhesive Coverage for Optical Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lens structures have poor structural stability and light transmission efficiency due to inadequate adhesive coverage between the lens cone and the lens, with the adhesive often located on light incidence or emitting surfaces, limiting adherence and affecting optical performance.
Innovation Solution
A lens structure with a contacting structure and an acrylate or moisture-curable adhesive covering over 70% of the side surface area between the lens cone and the lens, ensuring increased adherence without compromising light transmission efficiency by placing the adhesive between the contacting structures and side surfaces rather than on the light incidence or emitting surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is located on light incidence surface or light emitting surface of the lens, then adherence between lens cone and lens is improved, but light transmission efficiency deteriorates
Solution Approach 1:
The adhesive is applied selectively to specific regions: the light incidence surface of the lens cone and the peripheral side wall, while deliberately avoiding the light emitting surface and central optical regions. This localized application ensures strong adhesion where structural bonding is needed while preserving optical clarity in light transmission paths.
Solution Approach 2:
The adhesive application extends from a two-dimensional surface approach to a three-dimensional spatial distribution, covering the peripheral region between the lens cone and lens while maintaining optical performance in the central light path dimensions.
2Stability of the object's composition
If adhesive coverage area is increased to improve adherence, then structural stability is improved, but light transmission efficiency deteriorates due to adhesive blocking light paths
Solution Approach 1:
The adhesive is applied selectively to specific regions: the light incidence surface of the lens cone and the peripheral side wall, while deliberately avoiding the light emitting surface and central optical regions. This localized application ensures strong adhesion where structural bonding is needed while preserving optical clarity in light transmission paths.
Solution Approach 2:
The lens structure is segmented into distinct functional zones: a peripheral bonding zone where adhesive is applied for structural stability, and a central optical zone kept free of adhesive for optimal light transmission. This segmentation allows independent optimization of both structural and optical performance.
3Ease of manufacture
If adhesive is applied between partial peripheral surface of lens and partial side wall of lens cone, then structural assembly is simplified, but adherence between lens cone and lens deteriorates
Solution Approach 1:
The adhesive is applied selectively to specific regions: the light incidence surface of the lens cone and the peripheral side wall, while deliberately avoiding the light emitting surface and central optical regions. This localized application ensures strong adhesion where structural bonding is needed while preserving optical clarity in light transmission paths.
