Optical Fiber Cutter Adjustable Lid Angle Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical fiber cutters have a limited opening angle, making it difficult to position the optical fiber for cutting when the device is held with one hand or placed on a workbench, which hampers workability.
Innovation Solution
An optical fiber cutter with an adjustable opening angle switching mechanism that allows the cutter lid to be set to either a smaller or larger angle, facilitated by a switcher and stopper system, enabling easier operation when the cutter is held by hand or placed on a workbench, and a base attachment for stabilizing the cutter when on a workbench.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening angle of the cutter lid is kept small to facilitate one-handed operation, then ease of operation is improved, but workability when placing the cutter on a workbench deteriorates
Solution Approach 1:
The cutter lid opening angle is made dynamically adjustable through a switcher mechanism that allows transition between a first opening angle (smaller) and a second opening angle (larger). This enables the device to adapt its geometry based on operational context, resolving the contradiction between ease of closing and workability on workbench.
Solution Approach 2:
The opening angle parameter of the cutter lid is changed between two discrete states using the switcher and stopper mechanism. By switching between a smaller opening angle for one-handed operation and a larger opening angle for workbench placement, the system optimizes performance for different operational scenarios.
2Adaptability or versatility
If the opening angle of the cutter lid is increased to improve workbench operation, then workability is improved, but ease of closing the cutter lid deteriorates
Solution Approach 1:
The cutter lid opening angle is made dynamically adjustable through a switcher mechanism that allows transition between a first opening angle (smaller) and a second opening angle (larger). This enables the device to adapt its geometry based on operational context, resolving the contradiction between ease of closing and workability on workbench.
Solution Approach 2:
The opening angle parameter of the cutter lid is changed between two discrete states using the switcher and stopper mechanism. By switching between a smaller opening angle for one-handed operation and a larger opening angle for workbench placement, the system optimizes performance for different operational scenarios.
3Device complexity
If a fixed opening angle mechanism is used, then device complexity is reduced, but adaptability to different operating conditions deteriorates
Solution Approach 1:
The cutter lid opening angle is made dynamically adjustable through a switcher mechanism that allows transition between a first opening angle (smaller) and a second opening angle (larger). This enables the device to adapt its geometry based on operational context, resolving the contradiction between ease of closing and workability on workbench.
Solution Approach 2:
The opening angle parameter of the cutter lid is changed between two discrete states using the switcher and stopper mechanism. By switching between a smaller opening angle for one-handed operation and a larger opening angle for workbench placement, the system optimizes performance for different operational scenarios.

AI summary
An optical fiber cutter is provided, which can improve workability when performing an operation while either being held with a hand or placed on a workbench. The optical fiber cutter 1 comprises a cutter base 3 and a cutter lid 4 attached openably and closably to the cutter base 3. A slider 8 having a blade member for incising an optical fiber is attached to the cutter base 3 so as to be movable widthwise. A switching plate 15 is attached to a rear end part of the cutter base 3, while a switcher 16 is provided on the outer surface side of the switching plate 15. When the switcher 16 is at a first position, the cutter lid 4 engages a stopper, thereby attaining an opening angle of 35°. When the switcher 16 is at a second position, the engagement between the cutter lid 4 and the stopper is released, whereby the cutter lid 4 attains an opening angle of 70°.
