Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing volume measuring apparatuses are prone to inaccuracies due to improper user operation, such as incorrect posture or angle, leading to measurement errors when measuring the volume of objects.
Innovation Solution
A handheld volume measuring apparatus equipped with a processor, trigger button, first camera, and second camera that captures images from different angles, generates depth graphics, and sends an alarming signal if the measuring posture does not match the preset conditions, ensuring accurate volume data computation only when the posture is correct.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the volume measuring apparatus is made handheld and portable, then the ease of operation and mobility are improved, but the measurement precision deteriorates due to improper user posture and angle
Solution Approach 1:
The system captures images from multiple cameras, computes depth graphics, and analyzes whether the target object is fully contained and whether the capturing angle meets preset conditions. This feedback mechanism allows the system to evaluate measurement quality in real-time and provide guidance to the user for posture correction, thereby maintaining high measurement precision despite the handheld portable design
Solution Approach 2:
The system performs preliminary validation by analyzing the captured images and depth graphics before final volume computation. It checks whether the target object is fully contained in the field of view and whether the capturing angle satisfies preset conditions, preventing inaccurate measurements from being processed further
2Ease of operation
If the user operates the volume measuring apparatus without proper training or guidance, then the ease of operation is improved, but the measurement precision deteriorates due to incorrect posture
Solution Approach 1:
The system provides automatic feedback by analyzing captured images and depth graphics to determine whether measurement conditions are met. This eliminates the need for user training while maintaining high measurement precision through automated quality control
Solution Approach 2:
The system performs self-validation by automatically checking whether the target object is fully contained and whether capturing angles are appropriate, without requiring external guidance or user expertise. The system serves itself by identifying and correcting measurement quality issues
