Camera Module Connection Structure for Thinned Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera module assembly processes are complex, costly, and prone to damaging the printed circuit board due to the need for multiple steps and the use of adhesives, which also results in poor structural strength and increased defect rates, especially in thinned or narrowed bezel designs.
Innovation Solution
A camera device connection structure featuring a circuit board with locating holes, a lens assembly with mating sections and leg sections, and case assemblies with connection sections and leaf spring bodies that securely engage with the lens assembly, reducing the need for adhesives and fixing jigs, thereby enhancing structural strength and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is used to adhere the lens to the iron cases, then the lens can be secured to the case, but the production cost increases and the total volume enlarges
Solution Approach 1:
The patent extracts and removes the adhesive from the assembly system, replacing it with a mechanical connection structure. The lens is directly connected to the case body through a connection structure that eliminates the need for adhesive, thereby reducing production cost and simplifying the assembly structure while maintaining securing strength.
Solution Approach 2:
The patent introduces a connection structure as an intermediary component between the lens and the case body. This connection structure serves as a mechanical mediator that replaces the chemical bonding of adhesive with a physical connection, achieving both cost reduction and structural simplification.
2Stability of the object's composition
If a fixing jig is used to tightly press and locate the camera module during baking, then the assembly can be secured, but the pressing force becomes uncontrollable and may bend or damage the printed circuit board
Solution Approach 1:
The patent incorporates locating structures that are pre-integrated into the case body and lens assembly. These locating structures perform the positioning function in advance, eliminating the need for external fixing jigs during the baking process. The circuit board is pre-positioned by these locating structures, ensuring precision is maintained without requiring additional pressing equipment.
Solution Approach 2:
The case body and lens assembly are designed with self-locating features that enable them to automatically position and stabilize each other without external assistance. The locating structures on the case body engage with corresponding features on the lens assembly, creating a self-sufficient positioning system that eliminates dependency on fixing jigs.
3Volume of moving object
If the camera module is thinned or the bezel is narrowed, then the device size is reduced, but the structural strength decreases and the defect rate increases
Solution Approach 1:
The patent employs a composite connection structure that combines multiple functional elements (connection sections, locating structures, and integrating sections) into a unified assembly. This composite structure achieves high structural strength in a compact form factor, allowing the camera module to be thinned without compromising strength. The integrated design optimizes the use of space while maintaining robust mechanical connections.

AI summary
A camera device connection structure includes a circuit board, a lens assembly and a case assembly. The lens assembly is disposed on upper side of the circuit board and has a first mating section and a second mating section respectively disposed on two opposite sides of the lens assembly. The case assembly has a first case body and a second case body. The first and second case bodies are disposed on the upper side of the circuit board and respectively positioned on two sides of the lens assembly. The first and second case bodies respectively have a first connection section and a second connection section corresponding to the lens assembly. The first and second connection sections are respectively connected with the first and second mating sections of the lens assembly, whereby the structural strength of the camera device can be still enhanced in precondition that the camera device is thinned.
