Lifting Platform Controller Layout for Secure Actuator Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lifting platforms experience unreliable connections between controllers and actuators due to wires easily falling off from the controller, leading to disconnection and reduced reliability.
Innovation Solution
A controller design with openings at the frontside and lateral side of the control box for wire connection, integrated with snap-fit buckles and slots for secure attachment to the lateral beam, ensuring stable connections between the circuit board and actuators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If openings are arranged at lateral sides of the control box to optimize wire length, then wire length is reduced, but wires easily fall off causing disconnection
Solution Approach 1:
The patent changes the symmetric arrangement of openings (both at lateral sides) to an asymmetric arrangement where at least one opening is positioned at the front side of the control box. This asymmetric positioning prevents wires from being pulled straight out and improves connection reliability while still maintaining reasonable wire lengths.
2Ease of operation
If openings are arranged at lateral sides of the control box, then wire access is optimized, but connection stability deteriorates
Solution Approach 1:
The patent introduces a new spatial dimension for opening placement by positioning at least one opening at the front side of the control box, rather than only at lateral sides. This dimensional change in opening arrangement simultaneously maintains wire access convenience and improves connection stability.

AI summary
A controller for a lifting platform and a lifting platform are provided. The lifting platform includes a lateral beam and actuators, two actuators being provided and respectively disposed at two ends of the lateral beam. The controller includes a control box and a circuit board provided in the control box. The circuit board is connected with the actuators via wires, and a backside of the control box is connected to the lateral beam. Openings facilitating connection between the wire and the circuit board are arranged on the control box, and at least one of the openings is provided at a frontside of the control box.
