Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base module has at least two connection modules allowing submodules to be attached in different rotational positions, then the adaptability of the modular arrangement is improved, but the complexity of detecting and verifying correct configuration increases
Solution Approach 1:
The patent replaces manual verification of rotational position with automatic detection using sensing means. The sensing means detect the rotational position of submodules and send signals to evaluation electronics, which automatically verify correct configuration. This substitutes the mechanical/manual checking process with an automated sensor-based system, resolving the contradiction by making detection easier while maintaining adaptability.
Solution Approach 2:
The patent implements a feedback mechanism where sensing means continuously monitor the rotational position of submodules and provide information to evaluation electronics. The system compares detected positions against valid configurations and triggers countermeasures if incorrect. This feedback loop automates the verification process, reducing the difficulty of detecting and measuring configurational correctness while preserving the ability to accommodate multiple rotational positions.
2Reliability
If sensing means are added to detect rotational position and type of submodules, then the reliability of the safety system is improved, but the device complexity increases
Solution Approach 1:
The sensing means serve multiple functions: they detect both the rotational position of submodules and their type identification. The evaluation electronics perform multiple tasks including verifying rotational position, identifying submodule types, and determining whether the configuration is valid. This multi-functionality reduces the need for separate dedicated components for each detection task, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The patent combines the sensing means and evaluation electronics into an integrated detection system. The sensing means are positioned to simultaneously detect rotational position and submodule type, and the evaluation electronics process both types of information together to determine overall configuration validity. This merging of detection functions into a unified system improves reliability through comprehensive monitoring while avoiding the complexity of multiple separate detection systems.
3Reliability
If automatic countermeasures are implemented to prevent manipulations, then the security of the safety system is improved, but the device complexity increases
Solution Approach 1:
The patent implements preliminary anti-action by pre-programming valid configurations into the evaluation electronics before the system operates. The sensing means continuously monitor the current configuration and compare it against the pre-stored valid configurations. If an incorrect configuration is detected, the system automatically triggers countermeasures such as activating a safety switch or deactivating the machine. This preliminary setup of valid states and automatic comparison reduces the complexity of real-time decision-making while maintaining high security against manipulation.
