Dual Camera Module Assembly With Overlapped FPCBs for Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require replacement of entire assemblies when one component needs maintenance, leading to unnecessary costs and cumbersome redesigns due to non-independent component arrangements.
Innovation Solution
The electronic device features a housing with a printed circuit board and a camera module assembly where two camera modules are removably disposed in a single module housing, with their flexible PCBs overlapped and facing the same direction, allowing individual replacement of each module without affecting the other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple electronic components are disposed as a single assembly, then space utilization is improved, but replacement complexity increases when one component needs maintenance
Solution Approach 1:
The assembly housing is divided into multiple removable slots, each accommodating a separate electronic component (first camera module, second camera module). Each component can be independently removed and replaced by sliding it out of its designated slot, allowing maintenance of individual components without replacing the entire assembly.
2Quantity of substance
If multiple components share a single assembly housing, then manufacturing cost is reduced, but assembly redesign complexity increases
Solution Approach 1:
The assembly housing is designed as a universal structure with multiple standardized slots that can accommodate different types of electronic components. Each slot follows the same removable design pattern, allowing the housing to serve multiple functions while maintaining a consistent, simple structure that does not require complex redesign when components are updated.
Solution Approach 2:
The housing is segmented into independent slots with standardized interfaces, allowing each component to be manufactured and assembled separately. This modular approach simplifies manufacturing by breaking down complex assembly processes into simpler, repeatable operations for each slot.
3Area of stationary object
If flexible PCBs are overlapped and drawn in the same direction, then space efficiency is improved, but electrical connection complexity increases
Solution Approach 1:
Multiple flexible PCBs are overlapped and routed in the same direction through the housing, merging their pathways into a unified routing structure. This consolidates the electrical connection paths, making them easier to manage and connect to the main circuit board while maximizing the use of available space within the housing.
