Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locating devices lack the ability to accurately determine the orientation of items within an examination object relative to a reference variable, making it difficult for operators to efficiently locate and assign images to surfaces, especially in three-dimensional structures.
Innovation Solution
A handheld locating device equipped with a computation unit and sensor unit that determines the orientation of an item image with respect to a housing characteristic variable or gravitational acceleration, using a display unit to display the orientation and image for easy identification, and incorporates an inclination sensor for absolute orientation detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the locating device only detects presence of items without orientation information, then the device complexity is reduced, but the measurement precision and information completeness deteriorate
Solution Approach 1:
The computation unit pre-establishs a reference variable (housing axis or gravitational acceleration direction) before measurement, and pre-defines the coordinate system for orientation calculation. This preliminary setup enables precise orientation detection without requiring complex real-time computations during the actual locating operation.
2Loss of information
If the device provides detailed orientation information, then the loss of information is reduced, but the ease of operation may worsen due to information overload
Solution Approach 1:
The display unit presents orientation information in a localized and structured manner, showing the item image with its orientation relative to the reference variable at specific positions on the display. This localized presentation allows operators to access detailed orientation information without being overwhelmed by global information overload.
3Adaptability or versatility
If the reference variable is based on gravitational acceleration, then the adaptability to different operating positions is improved, but the device complexity increases due to additional sensing requirements
Solution Approach 1:
The locating device integrates multiple functions into the sensor unit and computation unit, allowing the same hardware to perform both traditional locating functions and gravitational acceleration-based orientation detection. This multi-functionality enables the device to adapt to different operating positions without requiring separate dedicated sensors for each function.
