Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual wiring processes are used to connect sensors and actuators in electronic door locks, then electrical connections can be established, but the process becomes labor-intensive and costly

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidwiring assembly efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the wiring system into modular components: a circuit board with pre-attached electrical connectors and a separate actuator assembly with corresponding connectors. This allows independent manufacturing and assembly of components, reducing manual wiring labor while maintaining connection reliability through standardized connector interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Electrical connectors are pre-attached to the circuit board during manufacturing before final assembly with the actuator. This preliminary action eliminates the need for manual wiring during assembly, reducing labor intensity and cost while ensuring proper electrical connections are established through the pre-configured connector interfaces.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple sensor and actuator configurations are supported, then device versatility increases, but inventory complexity and cost increase

Engineering Contradiction:
Improvesensor actuator configuration flexibilityVSAvoidinventory management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs universal connector interfaces and standardized mounting patterns that allow the same actuator and circuit board assemblies to support multiple sensor configurations. This universality enables a single base product to be adapted for different applications by simply changing which sensors are populated on the circuit board, reducing inventory complexity while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The circuit board is designed with designated locations for different sensor types, allowing selective population of sensors based on the specific application requirements. This local quality approach enables customization of sensor configurations without requiring different complete assemblies, simplifying inventory management while supporting device versatility.

Inventive Principle:
Principle #3Local quality

3Volume of moving object

If constrained real estate within the lock is utilized for electronic components, then compact design is achieved, but wiring routing becomes more complicated

Engineering Contradiction:
Improvelock assembly compactnessVSAvoidwiring harness routing complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent integrates the circuit board directly into the actuator assembly housing, nesting the electronic components within the existing mechanical structure. This nesting eliminates the need for separate wiring harnesses routing through constrained spaces, as electrical connections are established through direct connector interfaces between nested components, maintaining compact design while simplifying wiring.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

Locks, systems and methods of monitoring a lock, the lock having a hub with a slot rotatable by a handle to open and close a latchbolt. A locking member is moveable into and out of engagement with the hub slot to prevent and permit movement of the hub and latchbolt. A sensor on the lock, adjacent the hub and locking member, monitors a moving lock component. The sensor may sense the position of the locking member in or out of engagement with the hub slot. The sensor may be a reed switch actuated by a magnet on the moving lock component. The lock may further include a magnet mounted on the hub and the sensor may comprise a reed switch capable of being actuated by the magnet on the hub. The lock and system may include an external control unit having an alarm for controlling operation of the lock.
