Hinged Viewfinder Assembly for Easy Battery Access in Optical Scopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical devices, such as firearm scopes and telescopes, face challenges with battery access and shape convenience due to battery placement, leading to inconvenient mounting on rifles or tripods, and existing hinge connections do not provide easy access to removable batteries.
Innovation Solution
A hinged eyepiece connection that allows the battery compartment to move longitudinally within the tube-shaped body, enabling easy access to the removable battery while maintaining a compact and convenient device shape for mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the battery pack is integrated into the tube-shaped body of the optical device, then the device shape becomes convenient for mounting on rifles or tripods, but the user cannot easily access the battery for replacement
Solution Approach 1:
The optical device is divided into separate functional modules: the main tube-shaped body and the hinged eyepiece assembly containing the battery compartment. This segmentation allows the battery compartment to be accessed independently through the hinged eyepiece without disassembling the entire device, resolving the contradiction between maintaining a compact tube shape and enabling easy battery replacement.
Solution Approach 2:
The eyepiece assembly is designed with a hinged connection that allows it to pivot between a closed position (maintaining the tube shape) and an open position (providing access to the battery compartment). This dynamic mechanism enables the device to transition between different functional states, allowing both compact mounting capability and easy battery access.
2Duration of action of moving object
If a big capacity battery pack is used to ensure enough working time, then the energy supply duration is sufficient for hunting situations, but the battery pack dimensions become large making the device inconvenient to mount
Solution Approach 1:
The battery compartment is nested within the hinged eyepiece assembly, which itself is integrated into the main tube body. This nested arrangement allows the battery pack to be contained within the overall device envelope without increasing the external dimensions of the tube-shaped body, maintaining mounting convenience while providing sufficient battery capacity.
3Ease of operation
If the eyepiece is removed to access the battery, then the battery becomes accessible, but the eyepiece can be accidentally dropped and damaged or lost
Solution Approach 1:
The device is segmented into the main body and the hinged eyepiece assembly with the battery compartment. This segmentation allows the battery to be accessed by opening the hinge rather than removing the eyepiece entirely, eliminating the risk of dropping or losing the eyepiece while still providing battery replacement capability.
Solution Approach 2:
The hinged connection acts as an intermediary mechanism between the eyepiece and the battery compartment. Instead of directly removing the eyepiece to access the battery, the hinge provides an intermediate opening mechanism that allows battery access while keeping the eyepiece securely attached to the device.

Function Achieved in This Case
The hinged eyepiece design provides easy battery replacement and maintains a compact, mountable optical device shape, enhancing usability and convenience.
Implementation Method 1
The electronic viewfinder is attached to the battery compartment by a hinge connection pivotally connecting the electronic viewfinder to the battery compartment allowing the electronic viewfinder to fold against the battery compartment
Implementation Method 2
a locking nut, attached on the tube-shaped body, and configured to release and lock a longitudinal movement of an assembly of the electronic viewfinder and battery compartment
