Movable Handle Mount Adapter for Three-Plate Lens Camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera apparatuses with fixed handles struggle to accommodate changes in center of gravity and viewfinder mounting positions due to variations in peripheral equipment, leading to inefficiencies and obstacles when using lenses for three-plate type imaging sections with single plate type imaging bodies.
Innovation Solution
A camera apparatus with a handle mounting section that allows the handle to move in the front-back direction, a mount adapter that supports three-plate type lenses on a single plate type imaging body, and a shoulder adapter that adjusts to optimal positions, along with a support mechanism and filter disk unit for light quantity adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed handle is designed with optimized grip position and viewfinder mounting position according to the center of gravity, then the handling comfort is improved, but it becomes difficult to cope with changes in center of gravity caused by different peripheral equipment
Solution Approach 1:
The handle is designed to be movable in the front-back direction relative to the camera body, allowing the user to adjust its position dynamically. This dynamic adjustment capability enables the handle position to adapt to different center of gravity positions when various peripheral equipment is mounted, resolving the contradiction between optimized handling comfort and adaptability to different configurations
2Adaptability or versatility
If a large-sized handle is provided to accommodate various equipment configurations, then adaptability is improved, but the handle becomes an obstacle when not being used
Solution Approach 1:
The handle can be moved to different positions including a retracted position where it does not protrude from the camera body. This dynamic positioning allows the handle to provide extended functionality when needed while minimizing obstruction when not in use, resolving the contradiction between adaptability and obstacle generation
3Adaptability or versatility
If a detachable separate handle is provided, then adaptability to different center of gravity positions is improved, but it takes time to mount and dismount the handle
Solution Approach 1:
The handle is designed as a movable component that can be quickly adjusted along the front-back direction without complete detachment. This semi-detachable design provides the adaptability of a separate handle while eliminating the time-consuming mounting and dismounting operations, resolving the contradiction between adaptability and time loss
