Solution Overview

Problem

Users are required to carry multiple keys and manually check each lock for vehicles and their add-ons, such as trailers and roof boxes, which is inconvenient and lacks centralized control for locking and unlocking.

Innovation Solution

A central locking system that uses a mobile device to wirelessly connect to a central locking unit, allowing simultaneous locking and unlocking of vehicle locks and remote locks for various add-ons, such as trailers, roof boxes, and bike carriers, via near-field communication or Bluetooth, enabling centralized control and status monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate locks are used for vehicle and add-ons, then each lock can be independently secured, but the user must carry multiple keys and manually check each lock

Engineering Contradiction:
ImprovesecurityVSAvoidconvenience of locking and monitoring
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent combines multiple separate locking mechanisms (vehicle lock and add-on locks) into a single centralized locking system. The control unit receives a single locking command and simultaneously actuates all connected locks, merging the function of multiple keys and manual operations into one unified system. This resolves the contradiction by maintaining independent security for each lock while providing centralized control through a single key or mobile device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The centralized locking system provides universal control over multiple different types of locks (vehicle doors, trailers, roof boxes, bike carriers) through a single control interface. The system can identify and control various add-on types based on their unique identifiers, making the locking system multi-functional rather than requiring separate key systems for each add-on type.

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

2Loss of information

If manual checking of each lock is required, then the locking status can be confirmed, but the process is time-consuming and inconvenient

Engineering Contradiction:
Improvelocking status informationVSAvoidtime for checking locks
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system implements automatic feedback by having each lock send its locking status back to the control unit. The control unit then transmits this status information to the user's mobile device, providing real-time confirmation of whether each lock is locked or unlocked. This eliminates the need for manual checking while maintaining complete visibility of locking status, resolving the contradiction between information accuracy and time consumption.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The locking system performs self-monitoring and automatic status reporting without requiring user intervention. Each lock automatically detects its own state and communicates it to the control unit, which then informs the user. This self-service capability eliminates the manual checking process while ensuring the user has accurate information about all lock statuses.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If separate locking systems are used for vehicle and add-ons, then each can be controlled independently, but centralized control is not achieved

Engineering Contradiction:
Improvecompatibility with different add-onsVSAvoidnumber of separate locking systems
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control unit is designed with universal compatibility to work with multiple types of add-ons (trailers, roof boxes, bike carriers, caravans) through a single interface. Each add-on is identified by a unique identifier, allowing the system to adapt to different add-on types while maintaining a unified control structure. This reduces device complexity by replacing multiple separate locking systems with one multi-functional centralized system.

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

Solution Approach 2:

The system uses segmentation by assigning unique identifiers to each add-on type, allowing the control unit to distinguish and appropriately control different add-ons. This segmentation approach enables the centralized system to handle diverse add-on types individually while maintaining overall system unity, balancing adaptability with manageable complexity.

Inventive Principle:
Principle #1Segmentation
