Dual-Opening Camera Socket for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connection methods for camera modules in multimedia devices, such as board-to-board connectors and flexible printed circuit boards, face issues with large occupation volume, low reliability, and high production costs, particularly in dual-camera mobile phones where a data bus between cameras occupies valuable wiring space and requires multiple connectors.
Innovation Solution
A socket design with two openings allows for the direct insertion of two cameras, eliminating the need for a data bus between them, simplifying manufacturing, reducing production costs, and enabling an ultrathin design by integrating elastic pins and pins for secure electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two cameras each adopt two connectors (FPCB and socket) to connect to the circuit board, then the connection reliability is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent combines two separate connectors (FPCB and socket) into a single integrated socket structure that can simultaneously connect both cameras to the circuit board. This unified connector design maintains reliable electrical connections while reducing the total number of connectors from four to two, thereby simplifying the device structure and reducing production complexity.
Solution Approach 2:
The socket is designed with multi-functional capabilities to accommodate both cameras through a single connector structure. It provides both mechanical support and electrical connection functions for multiple camera modules, eliminating the need for separate FPCB and socket connections for each camera, thus reducing overall device complexity while maintaining connection reliability.
2Reliability
If a data bus is arranged between the main camera and the auxiliary camera, then the electrical connection is improved, but the area occupation on the main board increases
Solution Approach 1:
The patent introduces a shared socket as an intermediary structure that directly connects both cameras to the circuit board. This intermediary connector eliminates the need for a separate data bus between the cameras, as both cameras can independently communicate with the circuit board through the socket's multiple contact points, thereby reducing wiring space occupation while maintaining electrical connection reliability.
3Adaptability or versatility
If FPCB and socket are used for camera connection, then the connection flexibility is improved, but the occupation volume increases
Solution Approach 1:
The patent merges the FPCB and socket into a single integrated socket structure that provides both the flexibility of FPCB connections and the reliability of socket connections. This combined design eliminates the need for separate FPCB and socket components, thereby reducing the total occupation volume while maintaining connection flexibility for camera modules.
4Reliability
If two separate connectors are used for each camera, then the connection reliability is improved, but the production cost increases
Solution Approach 1:
The patent combines multiple connectors into a single socket structure that can accommodate both cameras. This reduces the total number of connectors from four to two, simplifying the assembly process and reducing production costs. The integrated socket maintains reliable electrical connections for both cameras while requiring fewer materials and less assembly time, thereby improving ease of manufacture.
Solution Approach 2:
The socket is designed as a universal connector that can simultaneously connect multiple camera modules to the circuit board. This multi-functional design eliminates the need for multiple separate connectors, reducing material costs and assembly complexity while maintaining connection reliability across all camera interfaces.
