Zoom Lens Module Rear Surface Mounting for Slim Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with high-performance zoom lenses face challenges in maintaining portability and usability due to the bulkiness of the zoom lens barrel assembly, which increases the device's thickness and weight, compromising user convenience when trying to operate a touch panel or view images.
Innovation Solution
The electronic device incorporates a motor unit and side key to drive the lens module, allowing for zoom-in/out functionality through touch panel inputs, with a unique internal mounting structure that positions the lens module on the rear surface and motor unit on the side, minimizing the protrusion and optimizing component placement for a slim design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high-performance zoom lens is mounted on a portable terminal, then the camera function is strengthened, but the portability and usability deteriorate due to increased thickness and weight
Solution Approach 1:
The patent repositions the lens module from a protruding configuration to a recessed position on the rear surface of the housing. The lens module is disposed in a lens module cavity formed in the rear surface, allowing the zoom lens to achieve high-performance optical functionality while maintaining a slim overall device profile and eliminating the need for a protruding grip structure.
2Adaptability or versatility
If a multi-stage zoom lens barrel assembly is used to implement multi-magnification zoom, then the zoom function is enhanced, but the number of components and device size increase
Solution Approach 1:
The patent integrates the motor unit directly with the lens module assembly, positioning it adjacent to the lens module on the rear surface. This merged configuration drives the lens module to perform zoom-in and zoom-out operations, eliminating the need for separate multi-stage barrel assemblies and reducing the overall number of components while maintaining high-performance zoom functionality.
3Length of stationary object
If the lens module is positioned on the rear surface with motor unit on the side, then the device maintains a slim form factor, but component placement becomes more constrained
Solution Approach 1:
The patent creates a dedicated lens module cavity in the rear surface with specific dimensional characteristics to accommodate the lens module and motor unit. The cavity has a depth and width configured to receive the lens module, allowing optimized component placement within localized regions while maintaining the overall slim profile of the device housing.

AI summary
Disclosed is an electronic device having a display unit exposed on a front surface and a lens module disposed on a rear surface. The electronic device includes: a motor unit positioned at one side of the lens module and configured to provide a driving force to the lens module; and a side key positioned at the other side of the lens module which is opposite to the one side of the lens module, the side key being positioned on any one of side end parts of the electronic device. The lens module may be positioned between the side key and the motor unit.
