Offset Lens Barrel and Reinforcement Plate for Corner Camera Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to mount a camera lens module close to the corner edge of a mobile device screen without compromising its structural integrity and size, given the increasing demand for higher screen ratios.
Innovation Solution
The lens module design offsets the center of the lens barrel from the lens holder, incorporating a reinforcement plate to enhance structural strength and reduce size, allowing the lens assembly to be biased towards the corner edge while maintaining the mounting position of the lens holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the lens module is mounted adjacent to the edge of the screen to increase screen ratio, then the screen ratio is improved, but the lens module cannot be positioned close enough to the corner edge due to size and strength requirements
Solution Approach 1:
The lens barrel center is intentionally offset from the lens holder center, creating an asymmetric configuration. This allows the lens module to be positioned closer to the corner edge of the screen while maintaining proper optical alignment, effectively reducing the distance from the corner edge without compromising optical performance
Solution Approach 2:
The patent introduces a reinforcement plate structure that adds structural support in a different dimensional approach. The reinforcement plate compensates for the reduced structural margin caused by moving the lens module closer to the edge, enabling closer positioning while maintaining strength requirements
2Length of moving object
If the lens module size is reduced to enable closer mounting to the corner edge, then the distance from corner edge is improved, but the structural strength is compromised
Solution Approach 1:
The lens holder is segmented into multiple components: the base lens holder structure and an additional reinforcement plate. This segmentation allows the main holder to remain compact for closer corner mounting while the separate reinforcement plate provides the necessary structural strength without increasing the overall footprint
Solution Approach 2:
The reinforcement plate adds structural support through an additional dimensional layer. Rather than increasing the size of the existing holder structure, the patent introduces a separate reinforcement element that provides strength in a different spatial configuration, enabling closer positioning without compromising strength
