Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional plumb and level determination devices using vial bubbles are prone to user error, time-consuming, and can provide false readings due to miscalibration, while laser levels are limited in application and expensive.
Innovation Solution
A sealed fluid chamber device with transparent or translucent material, marked with center lines and filled with a non-evaporating fluid, determines plumb, level, and angle accurately without vial bubbles or lasers, using gravity to maintain fluid alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional vial bubbles are used for level determination, then the device structure is simple and cost is low, but user error increases and measurement precision decreases
Solution Approach 1:
The patent uses a laser to project a visual copy (laser line) of the reference marking onto the workpiece, replacing the need for users to visually judge bubble position. The laser line serves as an optical copy of the precision reference, making the measurement result directly visible and eliminating subjective judgment error.
Solution Approach 2:
The patent replaces the mechanical bubble indicator system with an optical laser projection system. The laser-based optical measurement system substitutes the mechanical bubble-vial arrangement, providing more precise and easier-to-read measurements through direct visual projection of reference lines onto the workpiece surface.
2Measurement precision
If laser levels are used for level determination, then measurement precision improves and user error decreases, but device cost increases and application versatility is limited
Solution Approach 1:
The patent integrates multiple measurement functions into a single device by combining the laser projection system with both horizontal and vertical reference line capabilities. The device can function as both a level (horizontal reference) and a plumb line (vertical reference), providing multi-functionality that exceeds traditional single-purpose tools while maintaining measurement precision.
3Reliability
If traditional vial bubbles are used, then device cost is low, but reliability decreases due to miscalibration and breakage
Solution Approach 1:
The patent replaces the mechanical bubble-vial system with an optical laser system that projects reference lines directly. This substitution eliminates the mechanical components (vial, bubble, glass walls) that are prone to breakage and miscalibration, while the laser system provides consistent, reliable reference lines that are not susceptible to physical damage or calibration drift.
Solution Approach 2:
The laser projects an optical copy of the reference marking onto the workpiece, creating a visible reference line that serves as a direct visual indicator. This optical copying mechanism provides consistent and reliable reference lines without the reliability issues associated with physical bubble vials, such as breakage, evaporation, or calibration errors.
4Productivity
If vial bubbles are used for level determination, then device complexity is low, but productivity decreases due to time-consuming operations
Solution Approach 1:
The patent replaces the mechanical bubble indication system with an optical laser projection system that directly displays reference lines on the workpiece. This substitution eliminates the time required for users to carefully observe and interpret bubble position relative to markings, as the laser line provides immediate visual feedback, thereby increasing measurement speed and productivity.
