Lens Apparatus Preset Position Storage via Single Operation Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens apparatuses with preset functions require complex structures to store multiple preset positions, complicating their design and operation.
Innovation Solution
An optical apparatus with an adjustment unit, detection unit, storage unit, and operation unit that allows for the storage and recall of multiple preset positions using a single operation unit, simplifying the structure by detecting and storing states through a combination of sensors and memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation rings are provided to store multiple preset positions, then the preset function capability is improved, but the device structure becomes complicated
Solution Approach 1:
A single operation ring is designed to perform multiple functions by detecting different operation types (first operation vs. second operation). The same physical component (operation ring 110) can store different preset positions by recognizing different operation patterns, eliminating the need for multiple separate operation rings while maintaining full preset functionality.
Solution Approach 2:
The operation ring transitions between different operational states or modes. By detecting the type of operation performed on the operation ring, the system dynamically determines which preset position to store or recall. This dynamic behavior allows one static physical component to serve multiple functional purposes.
2Adaptability or versatility
If multiple operation rings are provided to store multiple preset positions, then the preset function capability is improved, but the ease of operation deteriorates
Solution Approach 1:
The operation ring serves as a universal control interface for all preset operations. Users interact with a single familiar component rather than learning multiple different controls, improving ease of operation while maintaining the ability to store and recall multiple preset positions through different operation types on the same ring.

AI summary
When a first or a second operation is performed on an operation unit included in a lens apparatus, a memory stores a first or a second state of a focus lens unit detected by an operation detection unit when the first or the second operation is performed. When the first or the second operation is performed on the operation unit after the memory stores the first or the second state, a focus driving unit puts a state of the focus lens unit into the first or the second state.
