Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with double-sided shooting functions require additional circuit boards for mounting second lens modules, increasing the size of the lens module assembly.
Innovation Solution
A double-sided lens module design where a single circuit board with dual interfaces supports both lens assemblies, sharing the same board to reduce size and enhance mechanical strength with reinforcement plates and adhesives, allowing for integrated double-sided shooting capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional circuit board is used to mount a second lens module for double-sided shooting, then the double-sided shooting function is achieved, but the size of the lens module assembly increases
Solution Approach 1:
The patent merges two lens modules onto a single circuit board, with each lens module mounted on opposite surfaces of the same board. This integration eliminates the need for separate circuit boards for each lens module, achieving double-sided shooting functionality while reducing the overall assembly size
Solution Approach 2:
The single circuit board serves multiple functions by simultaneously supporting both the first lens module and the second lens module. The board acts as a common mounting platform that enables dual-sided imaging capabilities, making the system more versatile without proportionally increasing size
2Strength
If reinforcement plates and adhesives are used to enhance mechanical strength, then the mechanical strength of the circuit board is improved, but the manufacturing complexity increases
Solution Approach 1:
The reinforcement plates are pre-positioned on the circuit board before mounting the lens modules. The adhesives are applied in advance to specific locations, allowing the assembly process to proceed systematically and reducing on-site manufacturing complexity while ensuring proper mechanical reinforcement
