Modular Wiring Device Terminal Block Installation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical wiring devices, such as switches and outlets, require complex and time-consuming processes for installation and removal, necessitating licensed electricians and incurring high costs due to the need for manual disconnection and reconnection of wires, which is not user-friendly and inefficient.
Innovation Solution
The introduction of a hand tool with release bars that can be inserted into channels of ramps to unlock and pull electrical wiring devices from support boxes, simplifying the installation and removal process by allowing plug-in devices to be easily locked and unlocked, enabling users to perform these tasks without professional assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wiring devices are manually disconnected and reconnected, then installation and removal can be completed, but the process becomes complex and time-consuming requiring licensed electricians
Solution Approach 1:
The device is segmented into modular components: a support box with mounting structure, removable wiring devices with terminal blocks, and connection mechanisms. This segmentation allows individual components to be easily installed and removed without affecting the entire system, eliminating the need for complex manual wire disconnection and reconnection.
Solution Approach 2:
Terminal blocks serve as intermediary components between wires and switching devices. Wires are connected to terminal blocks once, and the terminal blocks move with the devices. This intermediary mechanism simplifies device removal and reinstallation, as users only need to disconnect the device from the terminal block rather than manually rewiring all connections.
2Ease of operation
If licensed electricians perform manual wire disconnection and reconnection, then installation and removal can be completed, but costs increase due to professional assistance requirements
Solution Approach 1:
Wires are pre-connected to terminal blocks before device installation. The terminal blocks are prepared in advance with all necessary wire connections, allowing the device itself to be simply plugged in or unplugged without requiring time-consuming on-site wire manipulation by professionals.
Solution Approach 2:
The system enables end-users to perform device replacement themselves through simple plug-in and plug-out operations. The standardized interface and terminal block design allow users without electrical training to safely and easily replace devices, eliminating dependency on licensed electricians and reducing both time and cost.
3Reliability
If devices are individually wired to terminals, then electrical connections are established, but the process requires professional intervention and becomes inefficient
Solution Approach 1:
The electrical connection system is segmented into fixed terminal blocks and removable device units. Terminal blocks remain permanently mounted with wires securely connected, while devices are designed as self-contained units that can be quickly replaced. This segmentation maintains reliable electrical connections while dramatically improving installation efficiency.
Solution Approach 2:
Terminal blocks are designed as universal connection points that can serve multiple devices and wiring configurations. The standardized terminal block interface allows different device types to connect to the same wiring infrastructure, enabling efficient device replacement without compromising connection reliability or requiring custom wiring for each device.
