Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical switches, such as contactors, require additional control devices and extensive wiring for local and remote control, leading to a large size and complex wiring, which is not efficient for compact installations and smart control.
Innovation Solution
An electrical switch with a compact design integrating a relay assembly and a control assembly in a single module, utilizing wireless communication to remotely control the relay, reducing the overall volume and simplifying wiring, and incorporating dual circuit boards for improved space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional contactors use additional control devices and extensive wiring for local and remote control, then control functionality is achieved, but device size becomes large and wiring becomes complicated
Solution Approach 1:
The patent integrates the control assembly and relay assembly into a single contactor unit, merging previously separate components (contactor, control devices, wiring) into one integrated device. This eliminates the need for extensive external wiring and additional control devices, directly resolving the contradiction between control functionality and wiring complexity
Solution Approach 2:
The patent introduces a control board as an intermediary component that receives control signals and directly actuates the relay assembly within the same housing. This intermediary approach replaces complex external wiring systems with an internal signal transmission path, reducing wiring complexity while maintaining control versatility
2Adaptability or versatility
If conventional contactors include additional control devices, then remote control capability is achieved, but the overall size of the electrical switch becomes too large
Solution Approach 1:
The control assembly and relay assembly are merged into a single integrated unit housed together, eliminating the need for separate control devices mounted externally. This integration dramatically reduces the overall volume while preserving remote control capability through the wireless communication unit
Solution Approach 2:
The patent employs a wireless communication unit that operates in the electromagnetic dimension rather than requiring physical wiring connections. This dimensional shift from wired to wireless control eliminates the space required for control wiring and external control devices, reducing overall device volume
3Ease of operation
If conventional contactors use separate control modules, then control functions are provided, but the structure becomes complicated and installation space increases
Solution Approach 1:
The control board and relay assembly are merged into a single integrated structure within one housing, eliminating the need for separate control modules mounted on adjacent surfaces. This integration reduces the installation footprint from multiple separate components to a single compact unit
