Solution Overview
Problem
Photographic devices face inconvenience and increased weight due to the need for external power connections and multiple battery modules for lens drivers, making it difficult to rotate lenses while moving the device.
Innovation Solution
A lens driver with a mounting member for installing a battery, which is electrically connected to the driving assembly, eliminating the need for external power connections and reducing the number of battery modules required, thereby simplifying installation and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external connection cable is used to connect the lens driver to the external power source, then the lens driver can be powered, but the ease of operation deteriorates due to inconvenience when the cable is forgotten
Solution Approach 1:
The battery module is extracted from the photographic device and integrated into the lens driver itself, allowing the lens driver to be self-powered without requiring external connection cables. This resolves the contradiction by eliminating the cable dependency while maintaining power supply reliability.
Solution Approach 2:
The power supply system is segmented into independent battery modules that can be individually installed in each lens driver. This modular approach allows each lens driver to be self-sufficient, improving ease of operation while ensuring reliable power supply.
2Reliability
If multiple battery modules are installed for multiple lens drivers, then each lens driver can be powered independently, but the device complexity increases due to multiple battery installations
Solution Approach 1:
The power supply system is divided into independent battery modules, with each lens driver containing its own battery module. This segmentation enables independent power supply for each lens driver while keeping the overall system modular and manageable, resolving the contradiction between power independence and system complexity.
3Reliability
If multiple battery modules are installed on the photographic device, then each lens driver has dedicated power supply, but the weight of the photographic device increases
Solution Approach 1:
The battery modules are extracted from the main body of the photographic device and integrated into the lens drivers themselves. This extraction reduces the overall weight of the photographic device while maintaining reliable power supply for each lens driver through their respective integrated batteries.
4Adaptability or versatility
If multiple lens drivers are installed for different lens functions, then all lens functions can be controlled, but the installation complexity increases
Solution Approach 1:
Each lens driver is designed as an independent modular unit with its own battery module, allowing multiple lens drivers to be installed for different lens functions (zoom, focus, filter transmittance) without increasing overall installation complexity. The standardized modular design enables straightforward installation while achieving comprehensive lens function coverage.
