Lens Module Mounting Bracket Mechanical Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The bonding strength between lens modules and the housing of portable electronic devices is poor, leading to potential separation under lateral pressure.
Innovation Solution
A lens module design that includes a mounting bracket with a recessed receiving groove for an optical filter and a voice coil motor with a casing and connection plates, featuring screw threads and mounting holes for enhanced mechanical attachment to the device housing, thereby increasing the bonding strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive mounting is used to attach lens module to housing, then the assembly process is simple, but the bonding strength is poor and separation occurs under lateral pressure
Solution Approach 1:
The mounting bracket is divided into multiple functional segments: a body portion for positioning, a connection portion with screw threads for mechanical attachment, and a recessed receiving groove for securing the optical filter. This segmentation allows each part to perform its specific function optimally while maintaining overall structural integrity.
Solution Approach 2:
The connection portion extends from the body portion in a different spatial dimension, creating a three-dimensional mounting structure that engages with the housing through screw threads. This dimensional extension transforms the simple adhesive interface into a multi-point mechanical fastening system, dramatically improving bonding strength while maintaining assembly feasibility.
2Strength
If mechanical attachment with mounting bracket is used, then the bonding strength is improved, but the device complexity increases
Solution Approach 1:
The mounting bracket merges multiple functions into a single integrated component: it provides structural support for the lens module, contains the recessed receiving groove for the optical filter, and incorporates the connection portion with screw threads for housing attachment. This consolidation reduces the number of separate parts and simplifies the overall assembly process.
Solution Approach 2:
The mounting bracket serves multiple purposes simultaneously: it acts as a structural support element, a positioning feature through its recessed groove, and a fastening mechanism via its screw threads. This multi-functionality eliminates the need for separate adhesive layers and additional fastening components, reducing overall device complexity while maintaining enhanced bonding strength.
