Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing launch detection methods are used, then the system is simple to operate, but the reliability of launch detection is poor leading to unsafe motor activation
Solution Approach 1:
The patent combines multiple sensor types (accelerometers and touch sensors) into an integrated launch detection system. The accelerometers detect launch acceleration signatures while touch sensors detect launch touch inputs, and both sensor inputs are merged through a launch detector to determine launch conditions. This combination resolves the contradiction by improving reliability through multi-sensor validation while managing complexity through integrated processing.
Solution Approach 2:
The launch detector acts as an intermediary component that receives inputs from both accelerometers and touch sensors, processes these signals according to launch criteria, and outputs a determined launch condition. This intermediary layer isolates the complexity of multi-sensor integration from the motor control system, improving reliability while containing device complexity within a dedicated processing module.
2Reliability
If existing launch detection methods are used, then the device complexity is low, but the safety control is insufficient leading to accidental motor energization
Solution Approach 1:
The system performs preliminary detection of launch conditions by monitoring both acceleration signatures and touch inputs before motor activation. The launch detector evaluates sensor inputs against predefined launch criteria in advance of motor energization, ensuring that motors are only activated when genuine launch conditions are confirmed. This preliminary validation improves safety control while maintaining manageable device complexity through rule-based detection logic.
Solution Approach 2:
The system implements feedback by continuously monitoring sensor inputs (accelerometers and touch sensors) and using this information to determine launch conditions. The launch detector processes real-time sensor feedback to validate whether launch criteria are met, preventing accidental motor energization. This feedback mechanism improves safety control while containing complexity within the detection and decision-making layer.
3Productivity
If existing launch detection methods are used, then the system is simple, but the flight operations efficiency is poor due to unnecessary motor activation
Solution Approach 1:
The patent merges data from accelerometers (detecting launch acceleration signatures) and touch sensors (detecting launch touch inputs) into a unified launch detection process. By combining these sensor inputs and evaluating them together against launch criteria, the system accurately determines genuine launch conditions, preventing unnecessary motor activation and improving flight operations efficiency while managing detection system complexity through integrated processing.
Solution Approach 2:
The system replaces simple mechanical or single-sensor detection methods with an electronic multi-sensor detection system using accelerometers and touch sensors. This substitution enables more accurate and reliable launch condition determination through electronic signal processing, improving flight operations efficiency by eliminating false launches while containing complexity through electronic rather than mechanical implementation.

AI summary
Detection of a launch event of an autonomous vehicle may consider input from a variety of sensors, including acceleration sensors and touch sensors In some aspects, a method includes receiving a first input from a touch sensor, receiving a second input from an accelerometer, determining whether a launch of the autonomous vehicle is detected based on the first input and the second input, and controlling the autonomous vehicle in response to the determining. In some aspects, when a launch is detected, a motor of the autonomous vehicle may be energized. By detecting a launch event in this manner, improved safety and reliability may be realized. A reduced occurrence of false positive launch events may reduce a risk that the motor of the autonomous vehicle is energized when the vehicle has not actually been launched.
