Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate remote controls are used for different truck functions, then each function can be controlled reliably, but the system complexity and cost increase
Solution Approach 1:
The patent combines multiple separate remote controls into a single unified remote control device that can control all truck functions. The remote control includes a display showing multiple function icons and a single actuator that can select and execute different functions, eliminating the need for multiple separate control devices while maintaining reliable control for each function.
Solution Approach 2:
The remote control device is designed with universal functionality to control diverse truck operations including suspension, bunk area controls, and bodybuilder-specific equipment. The display dynamically adapts to show relevant function icons based on the current context, and the single actuator can trigger any displayed function, making one device perform the roles of multiple specialized controls.
2Device complexity
If a single unified remote control is used for all truck functions, then device complexity is reduced, but the ease of operation decreases due to the need to select from multiple functions
Solution Approach 1:
The remote control display is designed to be dynamic and adaptive, automatically changing the displayed function icons based on the current context such as the driver's position, active truck systems, and operational state. This dynamic adaptation ensures that only relevant functions are prominently displayed at any given time, simplifying the user interface despite the device's ability to control multiple functions.
Solution Approach 2:
The display acts as an intermediary between the single actuator and the multiple truck functions. It presents a simplified visual interface showing only the currently relevant function icons, mediating the complex mapping between one physical control element and numerous possible operations, thereby maintaining ease of operation while enabling comprehensive control.
3Reliability
If wired remote controls are used, then connection reliability is ensured, but the ease of operation is reduced due to physical constraints
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The remote control communicates with the truck's control unit via wireless signals, eliminating physical cables and connectors. This substitution maintains reliable communication while significantly improving accessibility, allowing the driver to operate controls from any position in the cab without being constrained by wire routing.
