Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing night vision binoculars lack adaptability due to fixedly connected eyepiece and objective lenses, limiting their ability to adjust to different observational demands.
Innovation Solution
Design of night vision binoculars with a replaceable objective lens featuring a mounting base, locking mechanism, sliding rail, and sealing rings, allowing for easy assembly, disassembly, and adjustment of the objective lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the objective lens is fixedly connected to the main body, then the structure is simple and stable, but the adaptability is poor and the lens cannot be replaced according to different demands
Solution Approach 1:
The objective lens is separated from the main body through a detachable mounting base structure. The mounting base includes a positioning cavity that receives the objective lens, and a locking mechanism that can be engaged or disengaged to secure or release the lens. This segmentation allows the lens to be independently replaced while keeping the rest of the binoculars structure intact.
Solution Approach 2:
The mounting base incorporates a dynamic locking mechanism with movable locking components that can transition between locked and unlocked states. This dynamic structure enables the objective lens to be firmly fixed during use while allowing easy removal when needed, providing flexibility without permanently increasing structural complexity.
2Ease of operation
If the objective lens is fixedly connected, then the product stability is maintained, but the ease of operation is reduced due to inability to replace lenses
Solution Approach 1:
The mounting base includes pre-positioned positioning protrusions and corresponding positioning cavities that guide the objective lens into the correct position during installation. The locking mechanism is pre-configured with movable locking pieces that automatically engage with positioning features on the lens, ensuring proper alignment and secure fixation without requiring complex adjustment procedures.
Solution Approach 2:
The locking mechanism incorporates elastic resetting components that automatically return the locking pieces to their engaged position after the lens is inserted. This self-resetting feature ensures the lens is securely locked without requiring manual intervention to activate the locking action, simplifying the user operation while maintaining reliable fixation.
3Adaptability or versatility
If a locking mechanism is added to enable lens replacement, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The mounting base integrates multiple functions into a single structure: positioning protrusions for alignment, movable locking pieces for securing the lens, and elastic resetting components for automatic engagement. By combining these elements into one integrated mounting assembly rather than separate mechanisms, the design achieves lens replaceability without proportionally increasing overall structural complexity.
Solution Approach 2:
The mounting base acts as an intermediary component between the main body and the objective lens. It provides the positioning and locking functions while remaining a separate, replaceable unit itself. This intermediary structure isolates the complexity of the locking mechanism from both the main body and the lens, allowing each component to remain relatively simple while achieving the desired replaceability function.

AI summary
The present disclosure provides night vision binoculars with a replaceable objective lens. The night vision binoculars include: a main body, an objective lens and a locking member. The main body is provided with a mounting base; the objective lens is provided with a locking hole and detachably inserted into the mounting base. The objective lens rotates in the mounting base; and the locking member is slidingly disposed on the main body and provided with a locking position and an unlocking position. When the locking member is in the locking position, the locking member is inserted into the locking hole; and when the locking member is in the unlocking position. The objective lens can be removed from the mounting base. Through the above structure setting, the user is convenient to disassemble the objective lens; and the night vision binoculars are simple in structure and convenient to use.
