Manual Pulse Generator Dial Press Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional manual pulse generating devices allow for unintended movement of machine tools when operated with one hand, as the enable switch and dial can be inadvertently activated together, leading to accidental movement.
Innovation Solution
A manual pulse generating device design that requires both hands to operate by incorporating a rotatable dial and a pulse generating unit within a casing, where the dial must be pressed towards the casing to enable axial movement, utilizing press detection units to ensure intentional operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the enable switch and dial are disposed separately for one-handed operation, then the ease of operation is improved, but the reliability deteriorates due to accidental activation
Solution Approach 1:
The enable function and dial operation are merged into a single integrated component. The dial incorporates both the rotational movement function and the enable switch function, requiring a pressing action to activate the enable state while simultaneously initiating pulse generation. This integration ensures that accidental activation cannot occur without intentional dual-purpose operation.
Solution Approach 2:
Instead of requiring separate actions for enabling and operating (first switch, then dial), the invention inverts the sequence by requiring the dial to be pressed first to enable operation, after which rotation generates pulses. This reversed logic ensures that the dial cannot generate pulses unless intentionally pressed to activate the enable state.
2Reliability
If the dial is made pressable to enable movement, then the reliability of intentional operation is improved, but the device complexity increases
Solution Approach 1:
The pressing detection function is merged with the existing dial structure and pulse generation circuitry. The same dial component that rotates to generate pulses also incorporates a press switch mechanism, eliminating the need for separate enable switches and reducing overall device complexity while confirming intentional operation.
Solution Approach 2:
The dial is designed to perform multiple functions: it can be rotated to generate pulses, pressed to activate the enable state, and potentially pulled to deactivate. This multi-functionality reduces the number of separate components needed, as the dial replaces both the traditional enable switch and the pulse generation dial that were previously separate elements.

AI summary
A manual pulse generating device is equipped with a rotatable dial, a pulse generating unit configured to generate drive pulses for commanding axial movement of a machine tool in accordance with an amount of rotation of the dial, and a casing having the dial disposed on a surface of the casing and accommodating the pulse generating unit in the interior thereof. When the dial is pressed toward the casing, the pulse generating unit enables the axial movement in accordance with the drive pulses.
