Linear Actuator Centralized Wiring via Plug-in Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear actuators have disordered internal wiring arrangements, making adjustments and replacements cumbersome and aesthetically unpleasing, with multiple interfaces complicating the design and requiring disassembly for wiring modifications.
Innovation Solution
A linear actuator design with centralized circuit wiring on a circuit board, featuring a connecting seat for connection terminals and a plug-in window on the housing for external cable connection, allowing for easy adjustment and replacement of wires through a single electric plug, reducing the number of interfaces and simplifying the internal wiring design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wires are individually routed to multiple interfaces on the housing, then electrical connections can be established, but the internal wiring arrangement becomes disordered and the housing appearance becomes complex
Solution Approach 1:
Multiple individual wire interfaces are merged into a single integrated connecting seat that accepts one external cable with multiple conductors. This consolidates multiple separate connection points into one unified interface, simplifying the housing appearance and internal wiring arrangement while maintaining the same electrical connection capabilities.
2Ease of repair
If the housing is disassembled to adjust or replace wiring, then wiring modifications can be made, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The electrical connection system is segmented into two independent parts: the internal connecting seat with connection terminals that remains permanently installed in the housing, and the external cable with electric plug that can be easily connected and disconnected. This allows wiring adjustments to be made by simply plugging or unplugging the external cable without disassembling the housing.
Solution Approach 2:
The external cable with electric plug serves as an intermediary component between the power source and the internal connecting seat. This mediator allows for easy connection and disconnection, enabling wiring adjustments without requiring housing disassembly.
3Adaptability or versatility
If multiple input-and-output interfaces are provided on the housing, then wire connections can be established, but the actuator appearance becomes unaesthetic and cumbersome
Solution Approach 1:
Multiple separate input-and-output interfaces are combined into a single connecting seat with multiple connection terminals. This consolidation reduces the number of external interfaces from multiple separate openings to one unified interface, improving the housing appearance while maintaining the same wire connection capabilities.

AI summary
A linear actuator comprises a housing, inside which a spindle assembly, a push rod assembly driven by the spindle assembly, a limit switch for limiting stroke of the push rod assembly, and a motor for driving the spindle assembly are mounted. A connecting seat is disposed on the circuit board for centralizing connection terminals. The motor is electrically connected to the connection terminals. The housing is provided with a plug-in window aligned to the connecting seat. An electric plug of the linear actuator passes through the plug-in window and is plugged into the connecting seat. The electric plug and the housing are fastened together via a mounting component.
