Camera Lens Adapter with Data Memory for Movie Camera Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera lenses without integrated data memories, position sensors, and standardized electric interfaces cannot be fully utilized in existing control systems for movie cameras, limiting their application in automatic setting of lens values such as focus, iris, and zoom.
Innovation Solution
A device that allows camera lenses without integrated data memories and position sensors to be connected to a movie camera by using a miniaturized electronic system with a data store and standardized electric interface, which reads and processes optics-related data from the lens, enabling control of settings like depth of field, and optionally includes position sensors and adjusting devices for motorized adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If camera lenses without integrated data memories and position sensors are used, then cost and complexity of the lens are reduced, but the lens cannot be fully integrated into control systems for automatic setting
Solution Approach 1:
The patent introduces an intermediary device (adapter ring or interface unit) that connects the lens to the control system. This intermediary contains the necessary data memory, position sensors, and communication interface, allowing lenses without these components to be integrated into automated control systems. The intermediary acts as a bridge between the simple lens and the complex control system.
Solution Approach 2:
The patent separates the control system into modular components: the lens itself remains simple, while the data memory, position sensors, and communication interface are separated into a distinct adapter or interface unit. This segmentation allows the lens to remain inexpensive and simple while still enabling full control system integration through the separate modular components.
2Adaptability or versatility
If position sensors and data memory are integrated into the lens, then control system integration is enabled, but manufacturing cost and complexity increase
Solution Approach 1:
The patent creates a universal adapter or interface unit that can be used with multiple different lens types. Instead of integrating sensors and memory into each specific lens, the universal adapter provides these functions for all lenses, reducing per-lens manufacturing complexity while maintaining control system integration capabilities across different lens models.
Solution Approach 2:
The adapter serves as an intermediary that adds the complex functions (data memory, position sensors, communication interface) without requiring modifications to the lens manufacturing process. This keeps lens manufacturing simple while enabling advanced control system integration.
3Adaptability or versatility
If standardized electric interface is implemented, then compatibility with control systems is improved, but additional components and complexity are added to the lens
Solution Approach 1:
The standardized electric interface is implemented in the adapter or interface unit rather than in the lens itself. This intermediary provides the standardized connection and communication protocols, enabling compatibility with control systems while keeping the lens structure simple and unchanged.
Solution Approach 2:
The electric interface components (contacts, communication circuitry, data memory) are separated into a distinct adapter unit, keeping the lens structure simple while providing standardized interface capabilities through the separate modular component.
