Camera Module Carrier Groove for Glue Overflow Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glue-limiting structures in camera module production fail to effectively control glue overflow, leading to contamination and potential failure of the camera module.
Innovation Solution
A carrier with a glue dispensing area and an outwardly extending groove designed to receive overflowing glue, ensuring controlled flow and preventing contamination by guiding glue away from critical areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a glue-limiting structure is provided far from the glue dispensing area, then the structure can be simpler and easier to manufacture, but the limiting effect on glue overflow is poor and cannot completely control glue flow
Solution Approach 1:
The carrier is divided into distinct functional zones: a glue dispensing area with a bonding area for glue application, and a separate groove area for receiving overflowed glue. This segmentation allows each zone to be optimized independently - the bonding area for precise glue dispensing and the groove area for capturing overflow, thereby achieving both ease of manufacture and effective glue control.
Solution Approach 2:
The groove acts as an intermediary structure between the glue dispensing area and the surrounding components. It receives overflowed glue from the bonding area and directs it away from critical areas, serving as a mediator that prevents glue contamination while maintaining a simple overall structure.
2Manufacturing precision
If the groove capacity is increased to ensure complete glue containment, then the limiting effect is improved, but the carrier area is increased and may affect assembly
Solution Approach 1:
The groove is positioned and dimensioned to provide adequate capacity for glue containment only where needed - adjacent to and surrounding the bonding area. The groove has a specific capacity of at least 1/4 of the volume of glue dispensed, which is sufficient to contain overflow without requiring excessive area elsewhere on the carrier. This local optimization balances glue containment effectiveness with minimal carrier area.
Solution Approach 2:
The groove extends outwardly from the bonding area in a radial direction, utilizing the radial dimension of the carrier. This positioning allows the groove to capture overflow from multiple directions while maintaining a compact overall footprint, effectively containing glue without significantly increasing the carrier's area.
3Manufacturing precision
If the groove is positioned close to the bonding area, then glue overflow is better controlled, but the bonding area for glue dispensing is reduced
Solution Approach 1:
The carrier surface is segmented into a bonding area for glue dispensing and a groove area for overflow reception. This segmentation allows the bonding area to be positioned optimally for glue application while the groove is positioned to capture overflow, ensuring both adequate bonding area and effective glue control without compromise.

AI summary
A carrier of a camera module to receive glue for fixing a lens structure thereon comprises a glue dispensing area, the glue dispensing area comprises a bonding area and a groove extending outwards from the bonding area, the groove is directly adjacent to the bonding area to receive glue overflowing from the glue dispensing area. The groove prevents glue dispensed in the bonding area from overflowing towards, or entering, the center of the carrier and improves the production quality of the camera module. The application also discloses a camera module including the above camera carrier.
