Caliper Trigger Mechanism for Consistent Measurement Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caliper measurements are prone to errors due to varying contact strengths between the caliper and the object being measured, making it difficult for users to consistently apply the appropriate measurement force, leading to inconsistent and inaccurate results.
Innovation Solution
A caliper measuring device with a measuring trigger mechanism and electronic control unit that forms a current circuit when the trigger button is pressed, allowing for consistent force application by connecting and disconnecting the circuit based on contact with the object, and includes a function display mechanism to transmit measured values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually pushes the caliper to enable contact with the object, then the measurement can be performed, but different contact strengths result in different measurement results
Solution Approach 1:
The patent introduces a force sensing device that provides real-time feedback on the measurement force applied by the user. The electronic control unit receives signals from the force sensing device and uses this feedback to automatically adjust or control the measurement process, ensuring consistent measurement force without requiring manual adjustment by the user.
Solution Approach 2:
The system performs self-regulation of the measurement force through the electronic control unit and force sensing device. The control unit automatically maintains the appropriate measurement force based on sensor feedback, eliminating the need for the user to manually control and standardize the applied force across different measurements.
2Measurement precision
If the user controls the measurement force to a fixed level, then measurement consistency can be improved, but the difficulty for the user increases
Solution Approach 1:
The force sensing device continuously monitors the measurement force and provides feedback to the electronic control unit. The control unit uses this feedback to automatically maintain the optimal measurement force, removing the burden of manual force control from the user while ensuring consistent and accurate measurements.
Solution Approach 2:
The patent replaces the manual mechanical control of measurement force with an automated electronic control system. The electronic control unit, aided by force sensing devices, substitutes for the user's manual effort in controlling and standardizing the measurement force, thereby reducing user difficulty while improving measurement consistency.
3Measurement precision
If force sensing devices are used to sense measurement force, then the measurement force can be monitored, but the device complexity increases
Solution Approach 1:
The electronic control unit serves multiple functions: it processes signals from the force sensing device, controls the measurement process, and interfaces with the display mechanism. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while still providing comprehensive force measurement and control capabilities.
Solution Approach 2:
The patent merges the force sensing, electronic control, and display functions into an integrated system. The electronic control unit combines multiple functions that could have been separate components, and the force sensing device is integrated with the caliper structure, reducing overall system complexity while maintaining precise force measurement capabilities.
