Centralized Data Processing for Building Machine Display Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building machines require complex and inflexible display units for showing operational variables and states, which are prone to mechanical stress and require multiple units for different operator control locations, limiting adaptability to new technologies and customer requirements.
Innovation Solution
A centralized data processing device generates display signals, allowing for flexible and reliable display of operational variables and states using standard software, with a conventional screen, and separate data buses for control and display data transmission, reducing complexity and mechanical stress on display units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex display unit with pixel display and custom programming is used at the operator control location, then operational variables and states can be displayed in the form of characters or images, but the display unit is subjected to relatively large mechanical stresses from vibrations, heat, cold, dust and dirt, and has large housing dimensions
Solution Approach 1:
The patent extracts the complex processing functions (signal generation, character/image rendering, programming logic) from the display unit and relocates them to a centralized data processing device. The display unit itself is reduced to a simple output device that only needs to display pre-processed signals, making it mechanically robust with small housing dimensions and resistant to vibrations, heat, cold, dust and dirt.
Solution Approach 2:
The patent uses a conventional screen (display) as a simple copy of the information processing function, rather than building a complex custom display unit. The centralized data processing device generates the visual information, and the display unit merely reproduces it, separating the intelligence from the physical display component.
2Ease of operation
If multiple operator control locations are provided on the building machine, then operators can control implements from different positions, but multiple complex display units are required, each needing all necessary components
Solution Approach 1:
The patent merges all display control functions into a single centralized data processing device that serves multiple operator control locations. Instead of having separate display units at each location, one centralized system generates and distributes display signals to multiple simple display outputs, dramatically reducing overall system complexity while maintaining full control capability at multiple positions.
Solution Approach 2:
The centralized data processing device performs multiple functions: it processes data from sensors, generates display signals, controls implements, and serves multiple operator locations simultaneously. This universal device replaces what would otherwise require multiple specialized display units, each needing identical components.
3Adaptability or versatility
If a customized display unit with specific programming is used for a particular application, then the display can be tailored to that application, but adapting to new technologies or customer requirements requires new display units or new programming
Solution Approach 1:
The patent extracts the programming and customization logic from the physical display unit and places it in the centralized data processing device. This allows software updates, new programming, and adaptation to new technologies to be implemented centrally without touching the display hardware itself. The display unit remains a simple, standardized component that can be easily manufactured and replaced if needed.
Data Source
AI summary
The invention relates to a building machine, in particular a road-building machine, having running gear and a chassis which is fitted with a working unit which has one or more implements. The building machine has a stored-program control device for controlling the implements of the working unit and a device for displaying operational variables or operational states in the form of characters or images. In addition to the stored-program control device, the building machine has a centralized data processing device which is embodied in such a way that operational variables or operational states can be displayed as characters or images with the device for displaying operational variables or operational states. The exchange of data between the stored-program control device and the centralized data processing device is carried out via a first data bus, while the exchange of data between the data processing device and the device for displaying operational variables or operational states is carried out via a second data bus.
