Multi-Camera Lens Attachment with Anamorphic Optics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens attachments for hand-held personal communications devices with multiple cameras are often bulky, complex, and designed for single-camera use, failing to efficiently adjust the field of view for devices with multiple cameras of varying specifications on the same side.
Innovation Solution
A removable optical attachment with an angular field-of-view-changing optic that simultaneously extends over the objective lenses of multiple cameras, providing optical power in one dimension to adjust the field of view without interfering with adjacent lenses, using either anamorphic lenses or prisms to redirect and expand the field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing lens attachments are used for multiple cameras, then field of view adjustment is achieved, but the attachment becomes bulky and complex
Solution Approach 1:
The optical attachment is divided into multiple independent lens elements, each designed to work with specific camera lenses. Each lens element can be separately manufactured and positioned, allowing the attachment to accommodate multiple cameras without requiring a single complex monolithic structure.
Solution Approach 2:
The attachment assembly is designed with a universal mounting structure that can accommodate different camera configurations. The lens elements are positioned to work with multiple camera lenses simultaneously, allowing one attachment to serve multiple functions across different camera setups.
2Reliability
If existing lens attachments are designed for single camera use, then optical performance is optimized, but the attachment cannot be used with multiple cameras
Solution Approach 1:
The attachment includes multiple discrete lens elements rather than a single lens, allowing each element to be optimized for its specific camera while the overall assembly works with multiple cameras. This segmentation maintains optical performance for each camera individually while enabling multi-camera compatibility.
Solution Approach 2:
Multiple lens elements are combined in a single attachment assembly that can be mounted to devices with multiple cameras. The lens elements are positioned and configured to work simultaneously with multiple camera lenses, merging individual optical functions into a unified attachment system.
3Volume of moving object
If lens attachments are made compact for multiple cameras, then device portability is improved, but optical quality may be compromised
Solution Approach 1:
The attachment uses adjustable and reconfigurable lens elements that can be dynamically positioned to optimize optical performance. The lens elements can be adjusted to account for variations in camera lens specifications, maintaining optical quality despite the compact size and multiple camera configuration.
