Level Meter Bar Display for Visual Threshold Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional level meters struggle to allow users to visually grasp the relative position of level setting values with respect to a container, as they only display parameters as character strings and numerical values, making it difficult to understand the threshold's position relative to the container's capacity.
Innovation Solution
A level meter with a transmission/reception unit, a level determination unit, and a display portion that shows the relative position of level setting values using a bar display whose length expands and contracts according to the determined level, along with container information, allowing users to easily visualize the level setting values in relation to the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If parameters are displayed as character strings and numerical values, then information is provided accurately, but users cannot visually grasp the relative position of level setting values with respect to the container
Solution Approach 1:
The patent transitions from one-dimensional numerical display to two-dimensional visual representation by introducing a bar display that shows the relative position of level setting values as a proportion of container capacity. This dimensional change allows users to visually perceive spatial relationships that were previously abstract in numerical form.
Solution Approach 2:
The patent creates a visual copy or representation of the container with level setting values marked as bars. This graphical copy allows users to intuitively understand the relative positions without requiring calculation, as the visual representation directly mirrors the spatial relationship between levels and container capacity.
2Device complexity
If only numerical values are displayed, then the display is simple, but users must calculate and determine relative positions manually
Solution Approach 1:
The display system performs the calculation and visual representation function automatically. The bar display is generated based on the level setting values and container capacity, eliminating the need for users to manually calculate relative positions. The system serves itself by automatically providing visual context.
3Ease of manufacture
If level setting values are displayed without visual context, then the display is straightforward, but users cannot intuitively understand the relationship between thresholds and container capacity
Solution Approach 1:
The patent merges the level setting value display with the container capacity visualization by overlaying bars representing threshold values onto a visual representation of the container. This combination provides both the numerical data and its contextual meaning within the container framework in a single display element.

Function Achieved in This Case
Enables users to intuitively understand the relative position of level setting values, improving user experience by providing a clear visual representation of the level settings within the context of the container's capacity.
Implementation Method 1
a transmission circuit that transmits a measurement signal for measuring the level, and a reception circuit that receives a reflection signal due to reflection of the measurement signal by the object

AI summary
Provided is a level meter that allows a user to easily visually grasp a relative position of a threshold with respect to a container when the user sets a threshold of a level. The display portion of the level meter displays a bar display whose length expands and contracts according to the value of the level of the object stored in the container. In addition, the display portion displays a relative position of the plurality of level setting values related to the level with respect to the container together with the bar display.
