Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If mobile devices are integrated into access control systems, then real-time access information can be provided, but the system becomes vulnerable to battery failure and theft

Engineering Contradiction:

Improveaccess informationVSAvoidsystem reliability

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The system divides access control functionality into separate modules: mobile device for authentication, wireless button for mechanical actuation, and lock for security. This segmentation allows the lock to function independently if electronic systems fail, while still enabling real-time access information through the mobile device when available.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system incorporates a wireless button as a backup mechanical actuator that can be used if the mobile device battery fails or the device is stolen. This beforehand cushioning ensures continuous access capability while maintaining the ability to provide real-time access information through the mobile device when functional.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Loss of information

If hard-wired electronic lock systems are used, then real-time access information can be obtained, but installation cost and complexity increase

Engineering Contradiction:

Improveaccess informationVSAvoidsystem complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system replaces hard-wired electronic connections with wireless communication (Bluetooth, NFC) between the mobile device, wireless button, and lock. This substitution eliminates the need for complex wiring installation while maintaining real-time access information capability through wireless data transmission.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The lock system is designed to accept multiple types of authentication (mobile device, wireless button, traditional key) and communication methods (wireless, mechanical). This multi-functionality allows the same lock to operate in different modes depending on availability, reducing installation complexity while maintaining information capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If traditional mechanical locks are used, then system simplicity is maintained, but security against theft and loss is insufficient

Engineering Contradiction:

Improvesystem complexityVSAvoidtheft and loss

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The system merges traditional mechanical lock components with electronic authentication and wireless communication capabilities. The wireless button combines mechanical actuation with wireless signaling, while the mobile device provides cryptographic authentication. This merging enhances security against theft and loss while keeping the mechanical foundation simple and familiar.

Inventive Principle:

Principle #5Merging (Combining)

4Adaptability or versatility

If multiple keys are required for multiple locks, then access to different locks is enabled, but user convenience decreases

Engineering Contradiction:

Improveaccess capabilityVSAvoiduser convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The mobile device and wireless button are designed as universal access tools that can authenticate with multiple locks in the system. A single mobile device or wireless button can provide access to numerous locks without requiring separate physical keys for each, significantly improving user convenience while maintaining broad access capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Systems and methods for providing redundant access control systems with removable wireless buttons are disclosed. According to some embodiments of the invention, the systems and methods include a smart lock with a button that is enabled to communicate to a network device, a central access server, or an administrator device. When a user requests access to the lock, the removable wireless button communicates the request to the network device, administrator device, or central access server. The removable wireless button is configured to communicate directly to the central access server and the administrator device, or indirectly through a network device. The button may be detached from the cylinder and docked onto a recharge station. In some embodiments, the removable wireless button includes an inertial module motion sensor that determines whether a door is open or closed.
