Small Measuring Device Base-Point Timing for Accurate Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small measuring devices, such as dial gauges and lever-type dial gauges, suffer from measurement inaccuracies due to shifts in position and posture caused by user operations for base point setting and measurement start instructions.
Innovation Solution
A small-sized measuring device equipped with a position detector, timer, and central control unit that sets the base point after a standby time, allowing for accurate relative positioning without direct user interaction during the measurement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user operates buttons to set and capture the base point (origin), then the base point can be set, but the position and posture of the measuring device are moved, resulting in measurement errors
Solution Approach 1:
The patent replaces the mechanical button operation system with a voice recognition system. The user gives voice commands to set the base point and start measurement, eliminating the need to physically press buttons that would move the measuring device. This substitution of mechanical interaction with acoustic field interaction resolves the contradiction by allowing operation without physical contact.
Solution Approach 2:
The patent introduces voice commands as an intermediary between the user and the measuring device. Instead of direct mechanical contact through buttons, the user's intent is transmitted through voice, which is processed by the voice recognition unit. This intermediary allows base point setting without physical movement of the device, resolving the position shift problem.
2Measurement precision
If the user adjusts the measuring device to the correct posture before measurement, then accurate measurement can be performed, but user operations during base point setting shift the posture and cause errors
Solution Approach 1:
The voice recognition system allows users to set base points and start measurements without mechanical button pressing. This maintains the carefully adjusted posture of the measuring device while still providing easy operation through voice commands, resolving the contradiction between posture accuracy and operational ease.
3Loss of time
If direct user interaction is required for base point setting, then the operation can be completed quickly, but position shifts and human errors occur
Solution Approach 1:
The voice recognition system enables rapid base point setting through simple voice commands without the need for precise mechanical button pressing. This reduces the time required while eliminating position shifts and human errors associated with manual button operations, thereby improving both speed and reliability.
Solution Approach 2:
The measuring device automatically recognizes voice commands and executes base point setting without requiring precise manual intervention. The system serves itself by interpreting voice intent and performing the appropriate functions, reducing human error and positioning shifts while maintaining efficiency.

AI summary
A small-sized measuring device includes a position detector that is provided on a main body and detects the position of an object to be measured, a timer that measures time, and a central control unit that controls overall operation. The central control unit accepts a base-point setting standby time set by a user and stores the base-point setting standby time. The central control unit measures elapse of the base-point setting standby time after accepting an instruction to start measuring time from the user, performs a base-point setting step of setting the position of the object to be measured detected by the position detector as a base point after the base-point setting standby time has elapsed, and then measures the position of the object to be measured as a relative position from the base point.
