Lens Apparatus Standard Setting Switch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In television image capture systems, when multiple photographers use the same lens apparatus, unintended functions can be activated due to differing settings, leading to missed critical image opportunities.
Innovation Solution
A lens apparatus with a storing unit that allows user-specified data to be rewritten to standard settings, using a display panel and changing unit to ensure consistent settings across all users, preventing undesired function activations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user-specified settings are stored and retained, then individual user preferences and custom functions are preserved, but unintended functions may be activated when different photographers use the same apparatus
Solution Approach 1:
The system performs preliminary action by automatically detecting when a setting change is intended and proactively switching from user-specified settings to standard settings before the undesired function activation can occur. This prevents the problem rather than reacting to it after activation.
Solution Approach 2:
The system uses feedback through detection means that monitor switch operations and setting states. When a switch operation is detected that would change settings under user-specified mode, the system receives this feedback and automatically transitions to standard settings to prevent unintended activation.
2Ease of operation
If multiple photographers individually set various settings on the optical apparatus, then each photographer can optimize settings for their preferences, but the second photographer may encounter operation of undesired functions
Solution Approach 1:
The control means acts as an intermediary between the switch operations and the function activations. It monitors the setting state and intermediates by automatically switching to standard settings when a change is detected, thereby preventing the harmful effect of undesired function operation while preserving photographer flexibility.
Solution Approach 2:
The system provides universality by offering both user-specified and standard settings modes. The control means can switch between these modes based on detected operations, making the apparatus adaptable to different photographers while maintaining a safe default state that prevents undesired activations.
3Adaptability or versatility
If diverse functions are added to the drive unit with preset and assignment functions, then the range of image capture is extended, but the complexity of settings increases
Solution Approach 1:
The system extracts the complexity management function by separating the control of setting modes from the actual setting operations. The detection means and control means extract the burden of managing diverse function settings from the photographer, automatically handling the transition between user-specified and standard settings.

AI summary
A lens apparatus includes a changing unit for changing a user-specified value in a user-specified data segment to a standard set value at any screen state of a display panel. Therefore, a setting information element for each function regarding image capture in the lens apparatus is changed to a standard setting information element by a particular operation. As a result, problems, such as the activation of an undesired function upon the operation of a switch on a drive unit, and the like, are solved.
