Solution Overview
Problem
Control cabinet lamps require flexible mounting solutions to adapt to varying installation conditions within control cabinets, ensuring proper illumination, cable routing, and air circulation while allowing for equipotential bonding and tool-free or tool-dependent attachment options.
Innovation Solution
A pivot arm mechanism with adjustable attachment means and a locking piece that allows the pivot arm to be fixed in different positions, enabling flexible mounting and equipotential bonding, with the locking piece providing pretensioning and secure attachment to the support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different attachment means are provided for flexible mounting, then adaptability is improved, but device complexity increases
Solution Approach 1:
The attachment means are segmented into multiple discrete options (first attachment means with first receptacle, second attachment means with second receptacle) that can be independently selected and combined. This allows the device to offer multiple mounting configurations without requiring a single complex integrated attachment system, thereby improving adaptability while managing complexity through modular segmentation.
Solution Approach 2:
The device base is designed with universal adaptability by incorporating multiple types of attachment means and corresponding receptacles that can accommodate different mounting scenarios (frame sections, flat parts, mounting plates). This multi-functionality approach allows a single device design to serve multiple mounting purposes without requiring separate specialized devices for each mounting type.
2Reliability
If a locking mechanism is added to fix the pivot arm in setting positions, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is designed to be self-servicing through the interaction between the locking piece and the receptacles. The locking piece automatically engages with the first or second receptacle to fix the pivot arm in the desired setting position, providing reliable mounting without requiring additional complex control systems or manual intervention mechanisms.
3Ease of operation
If the pivot arm is made freely movable for adjustment, then ease of operation is improved, but reliability of fixed positioning deteriorates
Solution Approach 1:
The pivot arm transitions between dynamic and static states based on operational needs. During adjustment, the pivot arm is freely movable (dynamic state) allowing easy repositioning. When mounting is required, the locking piece engages the receptacles to fix the pivot arm in the desired position (static state), providing reliable fixed positioning. This dynamic behavior allows the system to switch between ease of operation and positioning reliability as needed.

AI summary
The invention relates to an electronic device with a device base for mounting the electronic device on a support, wherein at least one pivot arm is partially taken up in a receptacle of the device base and partially protrudes from the device base, which arm is adjustable about a pivot axis parallel to a contact side of the device base, wherein, in a first setting position of the pivot arm, a first attachment means is arranged outside the receptacle and wherein, in a second setting position of the pivot arm, a second attachment means differing from the first attachment means is arranged outside the receptacle, characterized in that a recess opening into the receptacle is formed on a side wall of the device base, into which recess a locking piece is inserted, which is adjustable between a release position, in which it releases the pivot arm, and a locking position, in which it fixes the pivot arm optionally in the first or in the second setting position. The electronic device can be a control cabinet lamp in particular.
