Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual angle marking and reference mark methods are used, then the device complexity is low, but the measurement precision and manufacturing precision deteriorate due to inaccuracy in angle adjustment
Solution Approach 1:
The patent replaces manual mechanical marking methods with a digital inclinometer application on a smartphone. The inclinometer uses accelerometer sensors to digitally measure and display the angle in real-time, eliminating the need for manual angle markings and reference marks while significantly improving measurement precision.
Solution Approach 2:
The patent introduces a smartphone as an intermediary device between the operator and the bearing assembly process. The smartphone runs a specialized application that serves as a mediator, providing real-time angle feedback and lookup tables to guide the operator in achieving the correct bearing installation angle without direct manual measurement.
2Productivity
If manual angle marking methods are used, then the ease of operation is high, but the productivity deteriorates due to time-consuming trial and error adjustments
Solution Approach 1:
The patent implements real-time feedback through the inclinometer application, which continuously monitors and displays the current angle during bearing installation. This immediate feedback allows operators to adjust the locking nut position accurately and efficiently, eliminating time-consuming trial and error while maintaining operational simplicity through the user-friendly smartphone interface.
Solution Approach 2:
The patent provides lookup tables within the application that contain pre-calculated correct bearing installation angles for different bearing types. This preliminary preparation of reference data allows operators to quickly reference the correct angle without performing calculations or adjustments, significantly improving installation efficiency while keeping the operation simple.
3Reliability
If manual reference marks are used, then the device complexity is low, but the reliability deteriorates due to lack of real-time feedback and incorrect alignment
Solution Approach 1:
The patent replaces unreliable manual reference marks with a digital inclinometer system that provides continuous real-time angle monitoring. The smartphone application reliably tracks the angle throughout the installation process and alerts the operator when the correct angle is achieved, ensuring accurate alignment without the errors associated with manual marking methods.
