Height Gauge Multi-Chromatic Light Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height gauges require operators to divert their attention from the workpiece to read visual information, making complex measurements in noisy environments challenging and less intuitive.
Innovation Solution
A height gauge equipped with a motorized system, position encoder, and a multi-chromatic light-emitting device that provides visual cues near the workpiece, allowing operators to maintain focus on the workpiece while guiding them through measurements using synchronized light signals for detecting extremal points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a visual display is provided to show measurements, then measurement information can be displayed, but the operator must divert attention from the workpiece to read the display
Solution Approach 1:
The patent introduces an intermediary acoustic signal system that translates measurement information into auditory feedback. The acoustic device acts as a mediator between the measurement system and the operator, delivering measurement data through sound signals that can be perceived without visual distraction, thus resolving the contradiction between information display and operator attention focus.
Solution Approach 2:
The patent replaces the visual display mechanism with an acoustic signaling system. Instead of using optical information that requires visual attention, the system uses acoustic waves to communicate measurement data. This substitution allows the operator to receive information through a different sensory channel, maintaining focus on the workpiece while still accessing measurement information.
2Ease of operation
If acoustic signaling is added to indicate measurement points, then measurement guidance is improved, but the device complexity increases
Solution Approach 1:
The patent makes the acoustic device multi-functional by enabling it to perform multiple signaling tasks. The same acoustic system indicates not only when extremal points are reached but also provides real-time feedback during measurement operations. This universal approach allows a single added component to serve multiple guidance functions, reducing the overall complexity compared to adding separate signaling systems for each function.
Solution Approach 2:
The patent implements a feedback mechanism where the acoustic device provides real-time information about the measurement status to the operator. The system continuously monitors the measurement process and delivers immediate acoustic feedback when specific conditions are met (such as reaching extremal points). This feedback loop enhances operational ease by guiding the operator through the measurement process without requiring complex additional hardware, as the same acoustic system handles both initial signaling and ongoing feedback.
