Solution Overview

Problem

Existing lock cylinders require complete redesign and adaptation of evaluation electronics for different input systems and data transmission techniques, leading to high production and storage costs due to the integrated nature of evaluation electronics, antennas, and coupling devices.

Innovation Solution

The lock cylinder design separates the reading unit from the evaluation electronics, allowing the same evaluation electronics to be used across different types of input systems, with the reading unit generating a standardized access signal that can be evaluated by the electronics, and enabling easy replacement and adaptation of data transmission systems without altering the lock cylinder assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the evaluation electronics, antenna, and coupling device are integrated into a single unit, then the lock cylinder ensures reliable data transmission and secure operation, but it requires complete redesign and adaptation for different input systems, leading to high production and storage costs

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidadaptability to different input systems
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The lock cylinder system is divided into separate functional modules: a reader unit (with antenna and input interface) and an evaluation electronics unit (with coupling device). This segmentation allows the reader unit to be replaced or adapted for different input systems (transponder, RFID, contactless) while the evaluation electronics remains standardized, thus improving adaptability without compromising data transmission reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The evaluation electronics is designed as a universal component that can work with multiple types of reader units through standardized interfaces. This multi-functionality allows the same evaluation electronics to support different input systems (transponder, RFID, contactless, biometric) without requiring complete redesign, thereby reducing production and storage costs while maintaining reliable operation.

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

2Reliability

If the evaluation electronics are customized for each specific input system and data transmission technique, then the lock cylinder ensures optimized performance for that system, but it increases production, development, and storage costs

Engineering Contradiction:
Improvesystem performance optimizationVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The evaluation electronics is designed as a universal platform that can be configured to work with different reader units through software or programmable interfaces. This allows optimized performance for each specific input system without requiring complete hardware redesign, thus maintaining reliability while significantly reducing production and storage costs through standardized manufacturing processes.

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

Solution Approach 2:

The evaluation electronics incorporates programmable parameters and configurable settings that can be adjusted to optimize performance for different input systems and data transmission techniques. This parameter-based customization allows the same hardware platform to adapt to various requirements without physical modification, reducing manufacturing complexity and cost while maintaining system optimization.

3Productivity

If the reading unit is integrated with the evaluation electronics, then the lock cylinder ensures seamless data processing, but it prevents easy replacement and adaptation of data transmission systems

Engineering Contradiction:
Improvedata processing efficiencyVSAvoidease of replacement and adaptation
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system is segmented into a reader unit and evaluation electronics unit that are functionally separate but communicatively connected. The reader unit handles data acquisition and preliminary processing, while the evaluation electronics performs authorization and control functions. This segmentation maintains efficient data processing through dedicated functional modules while allowing independent replacement or adaptation of the reader unit for different data transmission systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A standardized communication interface acts as an intermediary between the reader unit and evaluation electronics. This intermediary layer enables seamless data processing by providing a uniform protocol for data exchange, while simultaneously allowing different reader units to be connected to the same evaluation electronics without direct integration, thus facilitating easy replacement and adaptation of data transmission systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A lock cylinder with a lock cylinder housing is provided. A knob shaft, rotatable by way of a knob, is mounted to rotate on one side or both sides of the lock cylinder. An authorization signal causes at least one electromechanically operating coupling device to connect a lock element to rotate in unison with the knob shaft and in order to operate a lock. The authorization signal is generated by evaluation electronics based on an input or input signal. It is proposed that at least one reading unit with an input unit to record the input and/or a receiving unit to receive the input signal is present, that the reading unit with the input unit and/or receiving unit is arranged in at least one knob and are spatially separated from the evaluation electronics, that the knob is connected electrically and mechanically releasable to the knob shaft, and that the reading unit generates, from the input or input signal, an access signal that can be evaluated by the evaluation electronics.
