Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional systems use multiple input devices to specify dimensions of multidimensional objects, then measurement precision and control are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple input functions (position indication, pressure detection, shape specification) into a single integrated position indicator device. The core body with tip allows users to specify both position and shape by combining positional movement with pressure application, eliminating the need for separate keyboard and mouse operations while maintaining precise dimension specification capability
Solution Approach 2:
The position indicator serves multiple functions: it acts as a position indicator through its core body and tip, a pressure sensor through the pressure detection element, and a shape specifier through the combination of position and pressure data. This multi-functional design replaces multiple specialized input devices with one universal tool
2Measurement precision
If conventional systems require simultaneous operation of multiple input devices, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent merges position indication and shape specification operations into a single unified input action. Users specify both position and shape by moving the position indicator to the desired location and applying appropriate pressure, combining what were previously separate keyboard and mouse operations into one intuitive gesture
Solution Approach 2:
The system automatically interprets the combination of position and pressure data to determine the intended shape specification. The processing device self-adjusts the object shape based on the pressure magnitude and position, eliminating the need for users to manually coordinate multiple devices or learn complex operation sequences

AI summary
A method for displaying a three-dimensional object based on user operation of a position indicator. The method includes defining a two-dimensional shape based on movement of a tip of the position indicator on an input surface; determining a direction in which the two-dimensional shape extends, based on at least one of a pressure applied to the input surface by the position indicator or an acceleration of the position indicator; generating a representation of a three-dimensional object extruded from the two-dimensional shape in the direction in which the two-dimensional shape is determined to extend; and displaying the three-dimensional object on a display.
