HMI Display Control with Dynamic Region Sizing and Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems fail to dynamically adjust the size and layout of display objects on a human-machine interface (HMI) in response to changes in screen size and user environment, leading to suboptimal visibility and operability.
Innovation Solution
A display control device with a display region setting unit, a display control unit, and a priority setting unit that adjusts the size and position of display objects based on screen size changes and user-defined priorities, ensuring optimal display and operability across varying environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the size of the split region is changed, then the display region can be divided into different sizes, but the display object cannot be dynamically adjusted to conform to the size change
Solution Approach 1:
The patent implements dynamic adjustment of display object size and layout based on the size of the split region. When the split region size changes, the display control unit automatically adjusts the display object's size, position, and arrangement to optimize visibility and operability for each specific region size scenario.
Solution Approach 2:
The patent changes multiple parameters of the display object simultaneously including size, position, arrangement layout, and selection priority based on the split region size. This multi-parameter adjustment ensures that the display object adapts comprehensively to different region sizes while maintaining optimal user interaction.
2Quantity of substance
If multiple display objects are arranged in the same arrangement region, then information density increases, but visibility and operability of individual objects degrade
Solution Approach 1:
The patent assigns different selection priorities to different display objects within the same arrangement region. Objects with higher priority are displayed with better visibility and operability characteristics, while lower priority objects are adjusted accordingly. This allows multiple objects to coexist in the same region while maintaining optimal interaction for the most important objects.
Solution Approach 2:
The patent dynamically adjusts the size, position, and display characteristics of individual objects based on their selection priority and the overall arrangement region size. High-priority objects receive more space and better positioning, while lower-priority objects are compacted or positioned less prominently, enabling effective display of multiple objects without sacrificing the usability of critical elements.
3Ease of operation
If the display object size is increased to improve visibility, then the arrangement region size must increase, but this reduces the number of objects that can be displayed
Solution Approach 1:
The patent adjusts multiple parameters including object size, position, and selection priority based on the arrangement region size. When the region is small, objects are displayed at reduced size with adjusted positioning to fit more objects. When the region is large, objects can be displayed at larger sizes with better spacing, maintaining visibility while increasing quantity.
Solution Approach 2:
The patent utilizes two-dimensional space optimization by adjusting both horizontal and vertical positioning of objects within the arrangement region. This allows efficient packing of multiple objects while maintaining adequate spacing for visibility and operability, effectively using the available spatial dimensions to balance quantity and quality of display.

AI summary
Display of a display object is changed more appropriately. A display control device includes: a display region setting unit configured to set a display region in accordance with a screen size of a display; a display control unit configured to control display of at least one or more display objects arranged in an arrangement region provided in the display region; and a priority setting unit configured to set relative priority among the display objects arranged in the same arrangement region, wherein the display control unit sets a size of the arrangement region correspondingly to the display region that is set in accordance with the screen size of the display, and controls display of the display objects based on the priority that is set among the display objects.
