Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat pump control solutions are complex, space-consuming, and expensive, requiring central interfaces and load management systems, which complicates installation and increases costs.
Innovation Solution
A flush-mounted heat pump control device installed in a standard electrical box with minimal connections (one to a power supply, one to a control unit, and two for heat pump control lines) that integrates with existing KNX systems or uses magnetic actuation, eliminating the need for complex logic units and load management systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex logic units and load management systems are used to control heat pumps, then the control functionality is comprehensive, but the device complexity and installation cost increase significantly
Solution Approach 1:
The patent extracts the essential control functionality from complex load management systems by implementing a simplified control unit that directly interfaces with the heat pump via standardized control lines (X1, X2). This extraction maintains core control capabilities while eliminating unnecessary system complexity and intermediate components.
Solution Approach 2:
The control unit is designed with universal interfaces that can work with different heat pump models and integrate with existing building automation systems through standard protocols. The device performs multiple functions including on/off control, temperature regulation, and system monitoring within a single compact unit, reducing the need for separate specialized devices.
2Adaptability or versatility
If central interfaces and load management systems are deployed, then the control capability is enhanced, but the installation space and cost increase
Solution Approach 1:
The patent merges the control unit, power supply interface, and heat pump interface into a single compact device that can be installed in a standard electrical junction box. This consolidation eliminates the need for separate control panels, wiring cabinets, and multiple interface devices, significantly reducing installation space while maintaining full control capability.
Solution Approach 2:
The control unit is designed to nest within existing electrical infrastructure, specifically standard junction boxes and cable conduits. The device utilizes existing cable pathways and mounting structures, effectively hiding the control system within the building's existing electrical architecture rather than requiring dedicated control system space.
3Measurement precision
If multiple connection cables are required for heat pump control, then the control precision is improved, but the installation effort and complexity increase
Solution Approach 1:
The patent segments the control connections into two distinct functional interfaces: power supply connections (L, N) and heat pump control line connections (X1, X2). This segmentation allows for modular installation where each connection type can be handled independently, simplifying the installation process while maintaining precise control through dedicated control lines for signaling and regulation.
