Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a compact, multi-functional actuation system is implemented, then device complexity is reduced and versatility is improved, but manufacturing precision and reliability requirements increase
Solution Approach 1:
The patent combines multiple functions (actuation, sensing, status detection) into a single integrated lock actuator assembly. The motor assembly, sensing assembly, and actuator components are merged into one compact unit that can be applied across multiple fenestration product types, reducing the number of separate components needed while maintaining multi-functional capability.
Solution Approach 2:
The lock actuator is designed as a universal system that can be adapted to various fenestration products including sliding glass doors, patio doors, and other window/door applications. The system provides multiple functions (locking, unlocking, status sensing, integration with home automation systems) through a single device platform.
2Ease of operation
If manual operation is permitted after actuation, then ease of operation is improved, but control precision and reliability may be compromised
Solution Approach 1:
The system dynamically transitions between automated and manual operation modes. The lock actuator can be actuated automatically via motor assembly through the transmission mechanism, but also allows manual operation by users. The system adapts its control characteristics based on the operation mode, providing both automated reliability and manual flexibility.
Solution Approach 2:
The transmission mechanism acts as an intermediary between the motor assembly and the lock assembly. It transmits actuation force from the motor while also allowing manual input to be transmitted to the lock mechanism. This intermediary component enables both automated and manual operation modes to function through the same mechanical interface.
