Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnifying devices for watchmaking and small parts inspection require multiple lenses for different magnifications, leading to practical issues such as storage, handling, and repetitive assembly/disassembly, which can cause damage and are cumbersome.
Innovation Solution
A monocular magnifying device with a movable second lens integrated into a mobile carriage that can be deployed or retracted, allowing modification of optical characteristics and magnification without the need for multiple lenses, using a slide mechanism and guide grooves for angular adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple monocular magnifiers with different magnifications are used, then different orders of magnitude can be observed, but the user must carry and manage multiple devices which is cumbersome and inconvenient
Solution Approach 1:
The patent combines multiple lenses with different magnifications into a single monocular magnifier body. The device integrates a first lens and a second lens that can be superimposed, allowing the user to achieve different magnification levels (e.g., 2.5x, 5x, 10x, 20x) without needing to carry multiple separate magnifiers. This merging of functions into one device directly resolves the contradiction by maintaining versatility while improving handling convenience.
Solution Approach 2:
The monocular magnifier is designed to perform multiple magnification functions through a single device. By incorporating interchangeable or superimposable lenses within the same body, the device becomes universal, capable of adapting to different inspection needs (different orders of magnitude) without requiring the user to switch between multiple specialized tools, thus resolving the contradiction between versatility and ease of operation.
2Adaptability or versatility
If interchangeable lenses are used in a monocular magnifier, then different magnifications can be achieved with a single device, but the user must repeatedly assemble and disassemble lenses which is tedious and can cause damage
Solution Approach 1:
The patent introduces a mobile carriage mechanism that allows the second lens to move dynamically between a retracted position and a deployed position where it superimposes on the first lens. This dynamic mechanism enables quick switching between different magnification levels without requiring the user to manually assemble or disassemble lenses. The automated or semi-automated movement of the carriage significantly reduces the time and effort required to change magnifications, resolving the contradiction between adaptability and time loss.
3Adaptability or versatility
If interchangeable lenses are used in a monocular magnifier, then different magnifications can be achieved, but the lenses require separate storage and careful handling to avoid damage
Solution Approach 1:
The patent places the second lens and its mobile carriage inside the internal cavity of the monocular magnifier body, nesting the additional optical element within the existing device structure. This nested arrangement eliminates the need for separate storage of additional lenses, as everything is integrated into the single magnifier body. The user simply operates the carriage mechanism to deploy or retract the second lens, greatly simplifying handling and reducing the complexity of storage and maintenance compared to managing separate interchangeable lenses.
4Adaptability or versatility
If additional lenses are superimposed using clips or clamps, then magnification can be modified, but the additional lenses may become detached during handling operations
Solution Approach 1:
The patent replaces the unreliable clip or clamp mechanism with a more robust mobile carriage system that guides and secures the second lens during deployment and retraction. The carriage mechanism, with its guide grooves and controlled movement, provides stable and reliable attachment of the second lens to the first lens, preventing detachment during handling operations. This mechanical substitution resolves the contradiction by maintaining adaptability while significantly improving reliability.
