Push Button Cover Prevents Unauthorized Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for protecting electrical devices from unauthorized access often require complex mechanisms with multiple buttons, which can lead to unintentional operation and increased complexity, making them unreliable and costly.
Innovation Solution
A device with a single button housed in a recess and covered by a plastic or metal cover that prevents unintentional actuation, featuring a design where the button is only accessible after the cover is partially removed and deformed, ensuring secure and ergonomic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple buttons are used to prevent unauthorized access, then security against unauthorized access is improved, but device complexity increases and unintentional operation risk increases
Solution Approach 1:
The protective function is segmented into two independent components: a cover element that must be removed and a button that must be pressed. This segmentation maintains security while simplifying the interface, as each component alone is insufficient to activate the protective function.
Solution Approach 2:
The cover element must be removed before the button becomes accessible. This preliminary action ensures that intentional activation requires a deliberate two-step process, preventing unintentional operation while maintaining a simple single-button interface.
2Device complexity
If a single button is used to simplify the device, then device complexity is reduced, but protection against unintentional operation is worsened
Solution Approach 1:
The cover element serves as an intermediary between the user and the button. It physically blocks access to the button in the normal state, requiring deliberate removal before the button can be pressed, thus preventing accidental activation.
Solution Approach 2:
The solution adds a spatial dimension to the activation process by introducing a cover element that must be removed from a different dimensional space (the front surface) before the button on the same surface becomes accessible. This multi-dimensional approach enhances protection while maintaining interface simplicity.
3Reliability
If the button is recessed to prevent accidental activation, then protection against unintentional operation is improved, but ease of operation is worsened
Solution Approach 1:
The cover removal serves as a preliminary action that deliberately prepares the system for activation. This intentional first step ensures that subsequent button pressing is a deliberate action, while the recessed design maintains protection against accidental activation.
4Loss of information
If the cover is made transparent to show the button, then visual indication is improved, but protection against unintentional operation is worsened
Solution Approach 1:
The cover's optical properties (transparency/opacity) are utilized to provide visual information about the system state. When the cover is intact, the button visibility is controlled; when removed or deformed, the state change is visually apparent, providing information without compromising security.

AI summary
The invention relates to a device for protecting a device against unauthorized access, wherein the device comprises protective means designed, in particular, to render the device permanently unusable. To enable reliable and simultaneously cost-effective protection of the device, it is proposed that the protective means comprise a (single) push button (1) for closing an electrical contact and a cover (4) for covering the push button (1), wherein the cover (4) is designed to prevent actuation of the push button (1) in a normal operating state of the device and to allow actuation of the push button (1) when the cover (4) is at least partially removed.
