Binocular Diopter and Focus Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Binoculars face issues where the diopter difference and focus position can be inadvertently changed during observation due to accidental operation of the diopter and focusing mechanisms, disrupting the viewing experience.
Innovation Solution
The design incorporates a diopter-adjustment-operation-preventing member and a focus-position-change-preventing member, which restrict the operational movement of the diopter adjustment wheel and focusing mechanism, ensuring that once adjusted, these settings remain unchanged. This is achieved through a configuration where the diopter adjustment wheel is locked in place by a diopter-adjustment-operation-preventing member and the focus position is secured by a focus-position-change-preventing member, using a mechanism that prevents accidental operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the diopter adjustment wheel is made operable for adjustment, then diopter difference can be adjusted, but it may be accidentally changed during observation
Solution Approach 1:
The diopter adjustment wheel is designed to be dynamically switchable between an operable state (for adjustment) and an inoperable state (for protection). The operation preventing member can be moved to cover the wheel, preventing accidental operation while allowing intentional adjustment when needed.
Solution Approach 2:
The operational state of the diopter adjustment wheel is changed by moving the operation preventing member between two positions: covering the wheel to make it inoperable, and exposing the wheel to make it operable. This parameter change controls accessibility.
2Ease of operation
If the focusing mechanism is made operable for focusing, then focus position can be adjusted, but it may be accidentally changed during observation
Solution Approach 1:
The focusing mechanism is designed to be dynamically switchable between an operable state (for focusing) and an inoperable state (for protection). The operation preventing member can be moved to cover the focusing operation portion, preventing accidental operation while allowing intentional focusing when needed.
Solution Approach 2:
The operational state of the focusing mechanism is changed by moving the operation preventing member between two positions: covering the focusing operation portion to make it inoperable, and exposing it to make it operable. This parameter change controls accessibility.
3Device complexity
If no operation preventing members are provided, then the structure remains simple, but accidental operation disrupts observation
Solution Approach 1:
The operation preventing member serves multiple functions: it acts as a protective cover for both the diopter adjustment wheel and the focusing operation portion, and it serves as a switch to control the operability of both mechanisms. This multi-functionality reduces the need for separate protective components.

AI summary
Providing a pair of binoculars that is able to prevent diopter from being changed after adjusting diopter difference by pushing down the focus knob after adjusting diopter difference so as not to touch the operating knob, and able to prevent the focus position from being changed after adjusting focus position by pulling out the focus knob to create a focus lock state after adjusting focus position.
