Solution Overview

Problem

Current window and door handles lack convenience and effectiveness in preventing burglaries, as they often require manual key operation and can be compromised by force or sabotage, leading to security vulnerabilities and inconvenience.

Innovation Solution

An operating handle with an integrated electromechanical lock, break monitoring device, and sabotage protection, featuring a predetermined breaking point and keyless personal identification, such as fingerprint recognition, to securely manage the locking and unlocking of windows or doors, triggering alarms if tampered with or forced open.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate key lock is used on the window handle, then security against burglaries is improved, but convenience of operation deteriorates due to frequent key retrieval and locking/unlocking actions

Engineering Contradiction:
Improvesecurity against burglariesVSAvoidconvenience of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical key-lock system with an electromechanical locking mechanism controlled by a breakaway point detection system. When the handle is forcibly moved, a breakaway point breaks, triggering an alarm and automatically locking the window, thus substituting manual key operation with an automated electromechanical system that provides both security and convenience.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If the window handle is locked during programmed times, then security is improved, but emergency escape capability deteriorates in case of danger

Engineering Contradiction:
Improvesecurity during programmed timesVSAvoidemergency escape capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic locking system where the locking state is not fixed but can be changed based on detected conditions. The breakaway point detection system allows the window to be forcibly opened even when locked by breaking the detection point, which then triggers an alarm and changes the system state, providing adaptability for emergency situations while maintaining programmed security during normal times.

Inventive Principle:
Principle #15Dynamics

3Reliability

If a predetermined breaking point is introduced in the handle, then protection against forced entry is improved, but structural integrity of the handle deteriorates

Engineering Contradiction:
Improveprotection against forced entryVSAvoidstructural integrity of the handle
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent segments the handle structure by introducing a predetermined breaking point that separates the handle into two functional parts: a main handle body and a breakaway section. This segmentation allows the handle to maintain overall structural integrity while having a specific weak point designed to break under forced entry conditions, triggering the security system without compromising the main structural components.

Inventive Principle:
Principle #1Segmentation

4Measurement precision

If the breakage monitoring device is continuously active, then detection precision of tampering is improved, but energy consumption increases

Engineering Contradiction:
Improvedetection precision of tamperingVSAvoidenergy consumption of monitoring device
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic monitoring through the breakage detection system that checks for tampering at specific intervals or upon trigger events rather than continuous monitoring. The breakaway point is designed to break and trigger the alarm system periodically when force is applied, providing sufficient detection precision while minimizing energy consumption by avoiding constant active monitoring of the entire system.

Inventive Principle:
Principle #19Periodic action

AI summary

The invention relates to an actuating handle (17), provided with a preferably electromechanical locking mechanism (8, 8a), having a predetermined breaking point (4) which is between a handle neck (21) and a grip part (1) and is in particular monitored by an electrical switch (3) that preferably also acts as an "opening detector". During authorised opening of the actuating handle (17), a programmed switch (A1) closes the circuit of the electrical switch (3), the circuit of the physical switch (A2) is then opened, and therefore the grip part (1) can be brought into an opening or tilted position without the alarm being triggered by the switch (3). After the actuating handle has been brought into the closure position, and after the electromechanical locking process (8, 8a), the switch (A1, A2) procedure is executed in a reverse sequence.
