Interchangeable Fixed Lens Caps for Compact Camera Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
DSLR cameras are large, heavy, and expensive, making them non-portable and sensitive to outdoor elements, and they lack the flexibility of changing magnifications without significant cost.
Innovation Solution
A camera system with interchangeable fixed lenses that are sealed to be waterproof, allowing for different magnifications and field of views without compromising image quality, and can be mounted on various objects or vehicles for versatile use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single variable magnification lens is used in a DSLR camera, then different magnifications can be achieved, but the camera becomes large, heavy, and expensive
Solution Approach 1:
The camera system divides the lens functionality into separate fixed lenses instead of using a single variable magnification lens. Each lens cap contains a different fixed lens (wide-angle, standard, telephoto), allowing magnification variation by simply changing lens caps rather than using a complex zoom mechanism, thereby reducing camera weight and complexity.
2Adaptability or versatility
If a single variable magnification lens is used in a DSLR camera, then different magnifications can be achieved, but the camera becomes large and costly
Solution Approach 1:
Instead of manufacturing one expensive variable magnification lens, the system segments the lens into multiple simple fixed lenses that can be produced more economically. Each lens cap with a fixed lens is simpler and cheaper to manufacture than a complex zoom lens, while still providing the versatility of different magnifications through lens cap interchangeability.
3Adaptability or versatility
If a DSLR camera is designed for versatility, then different magnifications can be achieved, but the camera becomes sensitive to outdoor elements
Solution Approach 1:
The lens caps serve multiple functions: they protect the camera lens from environmental elements (water, dust, scratches) and simultaneously provide different magnification options through interchangeable fixed lenses. This multi-functionality eliminates the need for separate protective covers and lens attachments, reducing sensitivity to elements while maintaining versatility.
4Weight of moving object
If a compact camera design is used, then portability is improved, but the ability to provide different magnifications is limited
Solution Approach 1:
The camera system introduces dynamic adaptability through interchangeable lens caps that can be quickly swapped to change magnification. Although each individual lens cap is fixed, the system as a whole becomes dynamically adaptable to different shooting scenarios, providing the versatility of a zoom lens while maintaining a compact, lightweight camera body.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The camera system is compact, lightweight, and cost-effective, providing optimal focus and image quality in various settings, including outdoor and underwater conditions, with the ability to switch lenses easily for different scenarios without adjusting focus.
Implementation Method 1
a camera that includes fixed lenses in respective caps that can be interchanged to change the magnification and/or the field of view
Implementation Method 2
The lens cap of the camera can be interchanged with other lens caps that have different respective lenses (e.g., wide angle lens, an intermediate lens, a zoom lens, a fish eye lens, etc.)
Data Source
AI summary
A camera system is disclosed. The camera system includes a camera that employs interchangeable fixed lenses. By replacing one lens cap with another lens cap, the field of view can be changed since each lens cap has a different fixed lens. The camera can also record images or video in a forward and a backward direction at the same time.
