Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional metal keys and codes are used for locking systems, then each lock can be secured, but a great number of keys and codes are required which increases complexity and inconvenience

Engineering Contradiction:

Improveability to access multiple locksVSAvoidnumber of keys and codes required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mobile unit serves as a universal key that can access multiple different locks. Each lock stores the mobile unit's unique address and user code, allowing a single mobile unit to function as multiple different keys for different locking members, thereby eliminating the need to carry separate keys for each lock.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of using physical keys that must be duplicated for each lock, the system creates a digital copy of the locking mechanism in the form of a mobile unit. The mobile unit contains a memory that stores the unique addresses and user codes of multiple locks, allowing it to replicate the key function across different locks without physical duplication.

Inventive Principle:

Principle #26Copying

2Reliability

If multiple metal keys and codes are used, then each lock can be secured, but it becomes inconvenient and inefficient to manage them

Engineering Contradiction:

Improvesecurity of locksVSAvoidconvenience of accessing locks

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system replaces the mechanical key system with a wireless communication-based electronic system. The mobile unit communicates with locks via wireless transmission of unique addresses and user codes, eliminating the need for physical key insertion and manual code entry, thereby improving convenience while maintaining security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mobile unit automatically handles the authentication process for multiple locks without requiring manual intervention for each lock. The system self-manages the identification and authentication by transmitting and comparing unique addresses and user codes, reducing the operational burden on the user.

Inventive Principle:

Principle #25Self-service

3Device complexity

If a wireless communication system is implemented, then the number of keys and codes is reduced, but communication security must be maintained

Engineering Contradiction:

Improvenumber of communication interfacesVSAvoidsecurity of wireless transmission

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system implements security on a local level by storing unique addresses and user codes specifically for each lock in the mobile unit's memory. Each lock has its own unique identification data that is transmitted and verified locally, ensuring that the wireless communication is secure and that only authorized access to specific locks is possible.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system performs preliminary authentication by transmitting and verifying unique addresses and user codes before allowing access to any lock. The mobile unit must first establish its identity and authentication credentials with each lock before the locking mechanism can be actuated, preventing unauthorized access.

Inventive Principle:

Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system allows for efficient management of multiple locks with fewer keys and codes, enhancing security and convenience by using a central processing unit and memory for address and code storage, and automatic operation modes.

Implementation Method 1

Each electrical locking member is associated with a first communication member for wireless communication over short distances. Each key member comprises a programmable, mobile unit comprising a second communication member for wireless communication over short distances.

AI summary

A locking system includes at least one electrical locking member for a door and at least one key member. Each electrical locking member is associated with a first communication member for wireless communication over short distances, and each key member includes a programmable, mobile unit including a second communication member for wireless communication over short distances. The electrical locking member is unlocked or locked by the fact that the second communication member encryptedly transmits an address unique to the second mobile unit, as well as an authorized user code to the first communication member.
