Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In low-voltage installation environments, the limited space in connection boxes makes the assembly and wiring of components extremely difficult and time-consuming due to the need for multiple devices to be installed without increasing space.
Innovation Solution
A tamper protection cover for surge protection devices on busbar systems, featuring a base body with a receiving subspace for a switching actuation lever and a separable side stem that defines a larger common receiving space, allowing flexible adjustment and ensuring tamper-proof installation by preventing lateral intervention through two distinct states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electrical components are installed in the connection compartment, then the functionality of the system is improved, but the assembly and wiring becomes extremely difficult and time-consuming due to limited space
Solution Approach 1:
The patent implements nesting by placing the electrical component (such as a circuit breaker) inside the housing of the surge protection device. The component is received in a receiving space formed by the housing, allowing multiple functions to be integrated within a single device envelope. This nested arrangement eliminates the need for separate installation space for each component, thereby improving productivity during assembly and wiring while maintaining enhanced system functionality.
2Adaptability or versatility
If the receiving space for electrical components is increased, then the adaptability for different component sizes is improved, but the space-saving installation advantage is lost
Solution Approach 1:
The receiving space is segmented into a base receiving area and an extendable receiving area. The lateral projection can be detachably connected to extend the receiving space when larger components are needed, or removed to maintain a compact installation profile. This segmentation allows the device to adapt to different component sizes while preserving the space-saving advantage for standard installations.
Solution Approach 2:
The receiving space is designed to be dynamically adjustable through the detachable lateral projection. The projection can be attached or detached via predetermined breaking points, allowing the receiving space volume to change based on the specific electrical component being installed. This dynamic configuration enables adaptability for various component sizes without permanently increasing the installation footprint.
3Ease of operation
If the electrical component is made accessible for assembly and wiring, then the ease of operation is improved, but tamper-proof installation and protection against unauthorized access is compromised
Solution Approach 1:
The electrical component is pre-installed within the housing during manufacturing, with connection terminals already positioned for wiring. This preliminary action allows professional installation and wiring to be performed easily during the initial assembly phase, while the component remains protected within the housing. The tamper-proof cover is then installed to seal the component, preventing unauthorized access while maintaining the ease of operation for authorized personnel during installation.
Solution Approach 2:
The housing acts as an intermediary structure that provides controlled access during installation while ensuring tamper-proof protection during operation. The housing includes a receiving space that accommodates the electrical component and connection terminals, allowing easy assembly and wiring by authorized personnel. After installation, the tamper-proof cover seals the housing, preventing unauthorized access while maintaining the integrity of the installed component.
4Device complexity
If a fixed-size receiving space is used, then the device complexity is reduced, but the adaptability for different electrical component sizes is limited
Solution Approach 1:
The receiving space is divided into a fixed base portion and a variable extension portion (lateral projection). The base receiving space provides a simple, fixed structure for standard components, while the lateral projection can be detachably added to accommodate larger components. This segmentation maintains low device complexity for standard installations while providing adaptability when needed.
Solution Approach 2:
The housing is designed with universal adaptability through the optional lateral projection. The same housing structure can accommodate both small electrical components using only the base receiving space and larger components by adding the lateral projection. This multi-functional design provides versatility for different component sizes without significantly increasing the base device complexity.

AI summary
The invention relates to a tamper-proof cover (10) for a surge protection device for installation on a busbar system. The tamper-proof cover (10) has a base body (28) that defines a receiving compartment (30) for a switching actuation lever (7) of an electrical component (6) received by the surge protection device. The tamper-proof cover (10) has a lateral extension (14) that is detachably connected to the base body (28) via at least one predetermined breaking point (32). The lateral extension (14) defines an additional compartment (34) which, together with the receiving compartment (30) of the base body (28), defines a common receiving compartment (38) for the switching actuation lever (7), which is larger than the receiving compartment (30) defined by the base body (28).
