Solution Overview
Problem
Existing electrical lock mechanisms are difficult to replace existing conventional cylinder lock mechanisms without significant modification or additional wiring, making them inconvenient for instant substitution.
Innovation Solution
An electrical lock mechanism with a lock barrel shaped like a conventional cylinder that can be easily fixed to a door, featuring a doorknob-driven assembly with a built-in motor and biometric authentication, allowing for wireless communication and operation without additional power sources or mechanical modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an existing conventional cylinder lock mechanism is replaced with an electrical lock mechanism, then locking and unlocking functionality is improved, but mounting complexity and time consumption increase significantly
Solution Approach 1:
The electrical lock mechanism is designed with a universal mounting interface that fits standard door configurations. The housing includes a mounting plate with screw holes that align with conventional lock installations, allowing the electrical lock to replace traditional locks without requiring custom fabrication or extensive modification of the door structure.
Solution Approach 2:
The electrical lock mechanism is divided into separable components including a housing, mounting plate, and internal mechanism. This segmentation allows for easy installation by mounting the housing first, then assembling internal components, and facilitates replacement without removing the entire assembly at once.
2Extent of automation
If an existing conventional cylinder lock mechanism is replaced with an electrical lock mechanism, then locking and unlocking functionality is improved, but installation time increases significantly
Solution Approach 1:
The mounting plate is pre-drilled with screw holes in standard positions that match conventional lock installations. The housing is pre-assembled with internal components before installation, allowing for quick mounting to the door without requiring on-site assembly of complex internal mechanisms.
3Reliability
If additional fastening means are used to mount the electrical lock assembly, then mounting security is improved, but ease of installation deteriorates
Solution Approach 1:
The mounting plate is designed with a universal pattern of screw hole positions that accommodate standard door configurations. This allows the same mounting plate to provide secure attachment across different door types without requiring custom fastening solutions or additional modification work.

Data Source
AI summary
An electrical lock system comprises an electric motor, a remote control unit for authenticating authorized users prior to granting permission and communicating such information to a motor (5) driver circuitry wherein said motor (5) is built-in in a doorknob whose axis of rotation is arranged coaxial to said cylinder's longitudinal axis such that said motor's shaft extend along a cylinder adaptor region integrating said doorknob to said lock cylinder. Said adaptor portion is coupled to a mechanical bloc connecting said adaptor region to a battery bloc and to said motor (5) through an intermediary body integral to said doorknob enclosing said motor (5) and gear mechanism.
