Solution Overview
Problem
Current secure grounding systems for electrical work, such as MALT devices, face challenges including high costs, cumbersome key-based operation, risk of key loss or breakage, and difficulty in managing multiple earthing clamps, leading to safety concerns and increased risk of electrocution during installation and removal.
Innovation Solution
The introduction of a secure MALT system with a BOUZER, an electronic monitoring and control device that eliminates the need for physical keys by providing a user-friendly, intelligent key-lock system, ensuring correct installation and removal procedures through electronic validation and control of earthing clamps and vice, and integrating with a centralized management system for authorization and tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If key-based locking systems are used for earthing clamps, then security control is improved, but ease of operation deteriorates due to key loss, breakage, and cumbersome handling
Solution Approach 1:
The patent replaces the mechanical key-based locking system with an electronic control system using a microprocessor, memory, and electronic interface. The electronic system stores authorization codes and validates user credentials, eliminating the need for physical keys while maintaining security control. This substitution resolves the contradiction by providing reliable security through electronic validation while improving ease of operation through contactless authorization.
Solution Approach 2:
The patent introduces an intermediary electronic control unit that mediates between the user and the locking mechanism. This unit verifies authorization codes and controls the electromagnetic actuator, serving as a smart intermediary that enhances security through validated access while improving operational ease by eliminating key handling. The intermediary process validates credentials before enabling clamp operation.
2Adaptability or versatility
If multiple earthing clamps are managed manually, then adaptability is improved, but reliability deteriorates due to human error in installation and removal sequences
Solution Approach 1:
The patent implements a feedback system where the microprocessor tracks the state of multiple earthing clamps and validates operation sequences. The system provides feedback by checking whether clamps are properly installed or removed in the correct order, preventing unsafe operations. This feedback mechanism maintains adaptability for managing multiple clamps while significantly improving reliability by eliminating human error in sequence management.
Solution Approach 2:
The patent applies preliminary action by requiring validation of authorization codes and verification of proper installation sequences before allowing clamp operations. The system checks prerequisites (authorization, correct sequence) before enabling actions, ensuring reliable operation while maintaining adaptability for multiple clamps through programmed validation rules.
3Ease of operation
If electronic control systems are introduced, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges the electronic control system components (microprocessor, memory, electromagnetic actuator, interface) into an integrated unit within the earthing clamp assembly. This consolidation improves ease of operation through unified control while managing device complexity by combining functions into a single integrated system rather than separate components. The merged design simplifies the user interface while encapsulating complexity internally.

AI summary
An earthing device comprises an earthing clamp and an earthing clip, both equipped with a mechanical locking mechanism, an electronically controlled and operated release device, and an electronic memory containing at least one unique identifier for the earthing clamp and at least one unique identifier for the earthing clip. Either the earthing clamp, the earthing clip, or both further comprise an interface for communicating with an external electronic control and monitoring device. This interface is capable of transmitting the stored unique identifiers to the electronic control and monitoring device and of receiving a release command for the respective release device from the electronic control and monitoring device.
