Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera device assembly methods are inefficient due to dependencies between electrical contacting and the alignment and connection of camera modules, which can lead to inaccuracies and increased forces during bonding, affecting the alignment and fastening between the objective device and image sensor.
Innovation Solution
A method for assembling camera devices that allows for independent alignment and connection of camera modules, using a bonded connection and a deflectable connection element to decouple alignment and bonding forces from electrical contacting, enabling precise alignment and stable connection without interference from electrical loads during bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical contacting is performed during alignment and connection of camera modules, then electrical connection is established, but alignment accuracy and bonding quality deteriorate due to forces acting on the interface
Solution Approach 1:
The patent divides the connection process into two independent stages: first, alignment and bonding of camera modules without electrical contacting; second, electrical contacting after bonding has cured. This segmentation eliminates the harmful interaction between electrical forces and alignment precision during the critical bonding phase.
Solution Approach 2:
The patent performs alignment and bonding actions before electrical contacting. The camera modules are aligned and bonded while the connection element is in a non-contacting state, ensuring that alignment accuracy is not compromised by electrical forces during the preliminary bonding stage.
2Device complexity
If connection element is used for both electrical contacting and mechanical connection, then device complexity is reduced, but alignment accuracy and bonding quality worsen due to coupled forces
Solution Approach 1:
The patent separates the mechanical connection function and electrical contacting function into distinct operational stages. The connection element serves mechanical connection during alignment and bonding, then performs electrical contacting separately after bonding curing, eliminating the coupling of forces that would otherwise degrade bonding quality.
Solution Approach 2:
The connection element is designed to be movable between a first position (for alignment and bonding without electrical contact) and a second position (for electrical contacting). This dynamic positioning allows the same component to fulfill multiple functions at different times without compromising bonding quality.
3Manufacturing precision
If alignment and connection are performed independently of electrical contacting, then alignment accuracy improves, but assembly process complexity increases
Solution Approach 1:
The patent employs a movable connection element that can dynamically switch between a first position (where it does not contact the contact region, allowing precise alignment and bonding) and a second position (where it contacts the contact region for electrical connection). This dynamic mechanism enables independent alignment and connection processes while managing overall assembly complexity through a single multi-functional component.
