Hermetic Control Panel with Movable Cover for Emergency Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control push-button stations for elevators and similar plants lack adequate protection against weather, dirt, and careless use, leading to malfunctions and safety risks, and are not suitable for use in wet conditions or aesthetically pleasing designs.
Innovation Solution
A hermetically sealed control push-button station with a movable cover that protects electric devices from weather and dirt while keeping the emergency button accessible, featuring a configuration that allows operation in wet conditions and compliance with safety regulations, and an attractive design suitable for exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the push-button station is hermetically sealed to protect against weather and dirt, then protection against weather and dirt is improved, but accessibility to the emergency button deteriorates
Solution Approach 1:
The cover is segmented to include a specific opening that exposes the emergency button while maintaining hermetic sealing for other components. This allows the emergency button to be accessible without compromising the protective sealing of the entire push-button station.
Solution Approach 2:
The cover provides differential protection: it maintains hermetic sealing for most components while creating a localized opening for the emergency button. This local quality change allows selective accessibility without compromising overall protection.
2Reliability
If the push-button station is enclosed in a hermetically sealed outer enclosure, then protection against weather and dirt is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The cover integrates multiple functions: it serves as both the protective hermetic seal and the access mechanism for the emergency button. By combining the sealing function and access function into a single component, the design eliminates the need for separate enclosures and complex assembly structures.
Solution Approach 2:
The cover performs multiple functions simultaneously: it provides hermetic sealing, protects internal components, and enables emergency access through its opening. This multi-functionality reduces the need for additional components and simplifies the overall device structure.
3Reliability
If the push-button station is mounted in an enclosed compartment, then protection against careless use is improved, but immediate access to the emergency button deteriorates
Solution Approach 1:
The cover is segmented to include a specific opening that exposes the emergency button while maintaining protection for other components. This segmentation allows operators to access the emergency button immediately without opening the entire enclosure, while still protecting internal components from careless use.
4Reliability
If the push-button station has a protective cover, then protection against weather and dirt is improved, but accessibility to electric devices deteriorates
Solution Approach 1:
The cover is segmented to include a specific opening for the emergency button, allowing selective access to critical components while maintaining protection for other electric devices. This segmentation enables protection without complete isolation.

AI summary
A control push-button station for plants comprises a box-like body (2) housing therein a plurality of electric contacts for one or more circuits of the plant, and having a side wall (3) upperly closed by an upper wall (4), an emergency button (6) located on said upper wall (4) and electrically connected to at least one first pair of electric contacts, at least one electric device (7, 8, 9, 10) located on the upper wall (4) and electrically connected to at least one second pair of electric contacts. The control push-button station comprises a protection cover (12) adapted to be movably associated with the box-like body (2) to move between an open position in which the electric device (7, 8, 9, 10) is accessible and a closed position in which the electric device (7, 8, 9, 10) is not accessible to an operator, with the emergency button (6) being accessible in both open and closed positions.
