Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combinations of control cabinet keys are difficult to handle due to their fixed connection, which limits ease of use and handling, especially when multiple keys are required for specialized applications.
Innovation Solution
A combination of control cabinet keys with detachable units connected via center parts, allowing for rotational movement in a predefined plane, enabling easy handling and torque application, with optional separable units connected by a chain or articulated connection, and varying lengths to accommodate different keyhole sizes without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If keys are fixedly connected in a combination, then structural strength for torque application is improved, but handling ease and accessibility deteriorate
Solution Approach 1:
The key combination is divided into multiple detachable units, each containing one or more keys connected to a center part. Users can separate the units to access individual keys or smaller subsets of keys, improving handling ease while maintaining structural integrity when units are connected
Solution Approach 2:
The connection between units is made detachable rather than fixed, allowing the structure to transition between connected (for strength) and separated (for handling) states. This dynamic configuration resolves the contradiction between needing structural strength and ease of operation
2Volume of moving object
If multiple keys are arranged in a compact combination, then portability is improved, but accessibility to individual keys deteriorates
Solution Approach 1:
By segmenting the key combination into detachable units, the system maintains a compact form when units are connected while enabling easy access to individual keys when units are separated. This segmentation allows the compactness and accessibility requirements to be satisfied in different operational states
Solution Approach 2:
The keys within each unit are arranged in a star-shaped configuration radiating from a center part, utilizing radial spatial arrangement. This dimensional organization allows multiple keys to be packed compactly while maintaining accessibility through rotational movement and unit separation
3Adaptability or versatility
If keys are made rotatable relative to each other, then versatility of configuration is improved, but structural stability deteriorates
Solution Approach 1:
The key combination is segmented into detachable units that can be separated and reconnected. Within each unit, keys can rotate relative to one another, providing configuration versatility. The segmentation ensures that rotational movement is contained within units, maintaining overall structural stability
Solution Approach 2:
The system incorporates both dynamic elements (rotatable keys within units) and stable elements (detachable unit connections). Keys can rotate to provide versatile configurations when needed, while the detachable unit structure maintains stability during operation and allows reconfiguration when required

AI summary
The invention relates to a combination (1) of control cabinet keys (2), individual keys being situated in the same plane but extending at a fixed angle (x) relative to one another and connected via a common center part (4, 5). Due to the fixed connection between the keys, during handling, a torque may be applied to a key (2) that is used. For ease of handling, a first unit (E1) and a second unit (E2) of keys extending at a fixed angle (x) relative to one another are provided, all units (E1, E2) have their own center part, and the units are detachably connected at their center parts (4, 5), and/or the keys are rotatable relative to one another, but only in a respective predefined plane.
