Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switchable sockets fail to meet the required current load standards and safety regulations, particularly in flush-mounted installations, due to limitations in design and space constraints, which poses a risk of electrical hazards, especially for children.
Innovation Solution
The use of miniature power relays, such as 10A relays, arranged vertically and at an angle to optimize installation space, with a printed circuit board design that includes recesses for the relays and control electronics, ensuring compliance with DIN 49440 standards while minimizing mechanical alterations to the chassis and maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional switchable sockets are used in flush-mounted installations, then the installation space is limited by standard dimensions, but the required current load standards and safety regulations cannot be met
Solution Approach 1:
The patent applies dimensional change by arranging the printed circuit board vertically behind the chassis rather than horizontally, utilizing the depth dimension of the installation space. This vertical arrangement allows sufficient space for both the switching elements and control electronics while maintaining compliance with front dimensional standards for socket outlets.
Solution Approach 2:
The patent implements nesting by integrating the control electronics directly onto the printed circuit board that also carries the switching elements, and positioning this entire assembly within the existing chassis structure. This nested arrangement maximizes space utilization within the standardized socket dimensions while providing all required safety functions.
2Productivity
If the installation space is reduced to meet standard dimensions, then the socket conforms to DIN 49440 standards, but the current load capacity and switching functionality are compromised
Solution Approach 1:
The patent utilizes the depth dimension by positioning the printed circuit board vertically behind the chassis, allowing high-current switching elements to be arranged in a configuration that provides adequate spacing for heat dissipation and electrical isolation, thereby maintaining current load capacity within standardized dimensions.
Solution Approach 2:
The patent applies local quality by providing enhanced cooling provisions specifically in the regions where high-current switching elements are mounted on the printed circuit board, while other areas of the socket maintain standard design characteristics. This localized optimization allows high current capacity without increasing overall installation space.
3Adaptability or versatility
If manual switches are used for socket control, then switching functionality is provided, but central control capability is not available
Solution Approach 1:
The patent implements multi-functionality by designing the control electronics to accept multiple types of control signals (manual switch inputs, central control signals, remote control inputs) through a unified interface on the printed circuit board. This allows the same basic control system to serve both local manual switching and centralized control functions without requiring separate control circuits.
Solution Approach 2:
The patent applies dynamics by making the control system adaptable - the control electronics can dynamically respond to different control modes (manual or central) based on the input signals received. This dynamic capability allows the socket to function in different control configurations without increasing physical complexity.
4Reliability
If sockets are constantly connected to voltage, then power availability is ensured, but safety risks for children increase
Solution Approach 1:
The patent applies preliminary action by implementing switching elements that can disconnect power before any hazardous situation occurs. The control system is designed to cut off voltage supply in advance when safety risks are detected or when not in use, preventing potential hazards while maintaining ready power availability when needed.
Solution Approach 2:
The patent implements preliminary anti-action by providing switching capability that can preemptively counteract the hazard of constant voltage connection. The control electronics and switching elements work together to prevent dangerous situations from arising in the first place, rather than merely responding to hazards after they occur.

AI summary
The socket has a support frame (10) for fastening in a flush box in an installation direction. A chassis (20) and contacts for voltage input lie behind the support frame. A circuit board (40) is arranged in the chassis and carries electrically controllable switching elements (R10) i.e. relays, and associated control electronics. The switching elements are arranged beside the chassis, so that the switching elements and/or the circuit board and the switching elements fill normative installation space.
