Sealed Safety Handle Assembly Against Industrial Access Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety handles for industrial machines and plants are vulnerable to disassembly, lack customization options, and do not provide evidence of tampering or disassembly attempts, and lack smart connectivity with control units.
Innovation Solution
A safety handle with a main body anchored to a movable part, an actuator interacting with a fixed part, and sealing means covering fixing members to prevent disassembly, along with customizable features and smart connectivity options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixing means (screws, pins, snap-in means) are made accessible for installation, then ease of installation is improved, but security against disassembly deteriorates
Solution Approach 1:
The handle is divided into two separate parts: a first part that is fixed to the movable part of the access, and a second part that is fixed to the fixed part of the access. This segmentation ensures that each part remains in place independently, preventing complete disassembly while maintaining ease of installation through modular assembly.
Solution Approach 2:
An intermediary element is introduced between the handle and the access parts to provide a secure connection. This intermediary mechanism allows for easy installation while preventing unauthorized disassembly, as the connection requires specific alignment and engagement that cannot be easily reversed.
2Reliability
If handle structure is made fixed and integrated, then security against disassembly is improved, but adaptability deteriorates
Solution Approach 1:
The handle is segmented into two separate parts that can be independently selected and configured. This allows different combinations of handle parts to be used with different access systems, providing adaptability while maintaining security through the integrated fixed nature of each part once installed.
Solution Approach 2:
The handle design incorporates universal features that allow it to be adapted to different access systems and configurations. The first and second parts can be configured to work with various types of access mechanisms while maintaining the same secure fixed connection method.
3Reliability
If sealing means are added to cover fixing means, then security against disassembly is improved, but device complexity deteriorates
Solution Approach 1:
The sealing function is merged with the existing handle parts rather than being added as a separate component. The first and second parts of the handle incorporate sealing features that prevent access to the fixing means, thereby providing security against disassembly without significantly increasing device complexity.

AI summary
A safety handle for the control of access for machines or industrial plants comprises a main body (3, 4) adapted to be anchored to the movable part (M) of the access (A) to be controlled and adapted to be gripped by a user for moving the movable part (M) of the access (A), fixing means for fixing the main body (3, 4) to the movable part (M) of the access (A), an actuator (2) to be associated with the main body (3, 4) and adapted to interact with control means associated with the fixed part (F) of the access (A) upon closure thereof for enabling the machine or industrial plant to be controlled, sealing means (11) suitable for covering the fixing means to prevent access from the outside.
