Rotating Locking Ring for Large Imaging Accessory Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems struggle to securely attach large and heavy accessory devices to imaging apparatuses, risking accidental detachment due to forces applied during use.
Innovation Solution
A mounting apparatus with a fixing member, first ring member, and locking member that engage and lock accessory devices using inclined surface portions and a biasing mechanism to maintain engagement, even under increased forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large-sized accessory device with large mass and long total length is mounted on the imaging apparatus, then the functionality and versatility of the imaging apparatus is improved, but the reliability of the mounting connection deteriorates due to increased forces that may cause the accessory device to be pulled out
Solution Approach 1:
The mounting apparatus is divided into multiple functional components: a first ring member with inclined surface portions for engagement, a locking member with corresponding inclined surface portions for applying pressure, and a biasing portion for maintaining the pressing force. This segmentation allows each component to specialize in a specific function, collectively achieving reliable mounting of large accessory devices.
Solution Approach 2:
The locking member is designed to be rotatable relative to the first ring member, transforming rotational motion into linear pressing motion through the inclined surface portions. This dynamic mechanism allows the system to adapt to different accessory device sizes and weights by adjusting the locking member's position and applying variable pressure through the biasing portion.
2Ease of operation
If a simple mounting mechanism is used, then the ease of operation is improved, but the strength of the mounting connection deteriorates under increased forces from large accessory devices
Solution Approach 1:
The locking member's rotatability provides a simple operational mechanism where users can easily rotate the locking member to engage or disengage the inclined surface portions, transforming a simple rotational motion into effective locking action without complex mechanisms.
Solution Approach 2:
The biasing portion automatically maintains the pressing force between the locking member and first ring member without requiring continuous user intervention. The inclined surface portions self-align and self-lock when the accessory device is mounted, providing automatic engagement and maintaining connection strength.
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 apparatus effectively prevents accessory devices from being pulled out, ensuring secure attachment and engagement, even with large and heavy devices, while allowing easy mounting and detachment without manual handling.
Implementation Method 1
the locking member includes a plurality of second inclined surface portions of which thicknesses in the optical axis direction change, and in a case where the locking member is rotated in the first direction, the second inclined surface portion overlaps the first inclined surface portion along a radial direction of the locking member, so that the locking member is pressed in the optical axis direction
Implementation Method 2
a biasing portion that biases the accessory device engaging with the first ring member is provided, in which the biasing portion is provided between a plurality of first inclined surface portions that are provided in the first ring member and of which thicknesses in the optical axis direction change
Data Source
AI summary
A locking member is rotatably supported, and in a case where the locking member is rotated in a first direction, the locking member presses a first ring member engaging with a lens barrel in an optical axis direction of the lens barrel to lock the lens barrel, and in a case where the locking member is rotated in a second direction, the pressing is released.
