Excavator Display Image Quality Partitioning for Lower Memory Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices in work machines face challenges in reducing memory usage without increasing cost, especially when displaying image data without outline portions, and mounting multiple display control devices can increase costs.
Innovation Solution
A work machine with a display device that stores and displays different quality image data for work and service mode screens, using high-quality image data for work mode screens and lower-quality data for service mode screens to reduce memory usage without additional costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-quality image data is stored for all display screens, then display sharpness is ensured, but memory capacity usage increases
Solution Approach 1:
The patent applies local quality by storing high-quality image data only for work mode screens where sharpness is critical for operator safety and efficiency, while storing lower-quality image data for service mode screens where display quality requirements are reduced. This selective quality approach optimizes memory usage while maintaining necessary display sharpness in critical operational contexts.
2Adaptability or versatility
If multiple display control devices are mounted to handle different display functions, then multi-functional display is achieved, but device complexity and cost increase
Solution Approach 1:
The patent implements universality by enabling a single display control device to perform multiple functions through software-based screen mode switching. The controller can dynamically switch between work mode screens and service mode screens, allowing one hardware device to fulfill the roles previously requiring multiple specialized display control devices, thereby reducing system complexity and cost while maintaining multi-functional capability.
