Optical Member Driving Mechanism with Integrated Electronic Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturized consumer electronic devices with lens modules face challenges in assembly and durability due to tiny components and wires that can detach or break when shaken or struck.
Innovation Solution
An optical member driving mechanism comprising a first module, a second module, a driving module, and an electronic member module, where the driving module drives the second module relative to the first, with an electronic member module including a lead frame connected to an external circuit through a package member that covers the electronic member and lead frame, enhancing assembly strength and preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electronic device is miniaturized, then the device size is reduced, but the components and wires become hard to assemble and may detach or break
Solution Approach 1:
The patent merges the electronic member, lead frame, and package member into a single integrated electronic member module. The package member simultaneously serves as both a protective cover and an assembly structure that integrates multiple components, preventing detachment and breakage while maintaining miniaturization.
Solution Approach 2:
The patent implements a nested structure where the electronic member is positioned on the lead frame, and both are covered and protected by the package member. This nested arrangement consolidates multiple components into a compact, stable unit that resists detachment and damage.
2Adaptability or versatility
If many tiny components and wires are used, then the device functionality is enhanced, but assembly difficulty increases and components may detach or break
Solution Approach 1:
The patent combines multiple tiny components (electronic member, lead frame, package member) into a pre-assembled electronic member module. This merging approach maintains the functionality provided by multiple components while significantly simplifying the assembly process, as the integrated module can be installed as a single unit.
3Strength
If the package member covers both electronic member and lead frame, then assembly strength is enhanced and detachment is prevented, but manufacturing complexity increases
Solution Approach 1:
The package member is designed to perform multiple functions simultaneously: it covers and protects the electronic member, provides structural support for the lead frame, and serves as an integration platform for all components. This multi-functionality enhances assembly strength while avoiding the need for additional separate components, thereby reducing manufacturing complexity.

AI summary
An optical member driving mechanism is provided, including a first module, a second module, a driving module, and an electronic member module. The driving module can drive the second module to move relative to the first module. The electronic member module includes at least one electronic member, at least one lead frame, and a package member. The lead frame is connected to the electronic member and an external circuit outside the optical member driving mechanism. The package member has a single material and covers the electronic member and the lead frame. The lead frame is exposed from the package member, and the electronic member is not exposed therefrom.
