Graphic Display Meter Pointer Transition Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional graphic display meters experience inconvenience when switching from motion blur display mode to normal mode due to a gap between the two modes, causing the vehicle operator to recognize both images simultaneously, especially when the pointer speed is between stopped and high speeds.
Innovation Solution
A graphic display meter that displays a motion blur pointer image at high speeds and a normal pointer image at lower speeds, with multiple aligned pointer images transitioning between the two modes, where the multiple images are selected based on the space between the modes and gradually change color from the motion blur to normal image side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion blur display mode is used when pointer moves fast, then after-images and multiplicity of pointer images are eliminated, but when switching to normal display mode at lower speeds, a gap appears between the two display modes causing operator inconvenience
Solution Approach 1:
The patent introduces an intermediary transition display mode that includes multiple aligned pointer images positioned between the motion blur pointer image and the normal pointer image. This intermediary display acts as a mediator during mode switching, filling the gap that would otherwise cause operator inconvenience. The multiple pointer images are arranged to bridge the spatial difference between the two display modes, creating a smooth visual transition.
Solution Approach 2:
The patent implements dynamic switching between different display modes based on pointer rotation speed. The system automatically transitions from motion blur display mode at high speeds to normal display mode at lower speeds, with an intermediary transition mode in between. This dynamic adaptation ensures optimal display quality across all operating conditions while maintaining continuity.
2Reliability
If multiple pointer images are displayed during mode transition, then the gap between motion blur and normal pointer images is filled, but the complexity of image selection and display increases
Solution Approach 1:
The patent segments the transition process into distinct stages: motion blur display mode, transition display mode with multiple aligned pointer images, and normal display mode. By dividing the transition into manageable segments with clearly defined pointer image arrangements, the system manages complexity through structured organization rather than random or chaotic image generation.
Solution Approach 2:
The patent utilizes parameter changes in pointer rotation speed to trigger mode transitions. The system monitors the pointer rotation speed parameter and automatically switches between display modes based on predefined thresholds. This parameter-driven approach simplifies control logic by using a single measurable parameter (rotation speed) to determine display mode, reducing the need for complex decision-making algorithms.

AI summary
The object of the invention is to provide an improved graphic display meter which is prevented from causing inconvenience to the vehicle operator, when a motion blur display mode is switched to a normal display mode.When a motion blur pointer image 10 is switched to a normal pointer image 20a, multiple pointer images 20 including the normal pointer image 20a are displayed adjacent to or in abutment with a leading part of the motion blur pointer image 10 in a direction where the pointer is rotating. The multiple pointer images 20 are consisted of the normal pointer image 20a and a plurality of auxiliary pointer images 20b, which are aligned with one another and are positioned in close proximity to the normal pointer image 20a. The multiple pointer images 20, a plurality set of which have been stored as data in advance, are selected on the basis of a space between the motion blur pointer image 10 prior to the switching of the pointer image and the normal pointer image 20 after the switching of the pointer image.
