Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric pushing rods face issues with conductive wires breaking due to touch and friction from the rotor and limited inner space, leading to messy and damaged wiring.
Innovation Solution
An electric pushing rod design featuring a motor, transmission, sensor, and wire protector cover, where the wire protector cover secures conductive wires and prevents them from being damaged by gears, while also allowing space for wiring within a compact structure, using a reduction gear set, leadscrew, and expansion rod, and includes a temperature sensing member and electrostatic conductive members for static protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the displacement sensor is disposed near the rotor for easy detection, then the displacement control precision is improved, but the sensor is easily broken by touch, winding and friction from the rotor
Solution Approach 1:
The motor is divided into separate components: the rotor remains in the motor body while the displacement sensor is relocated to the end cover. This segmentation allows the sensor to be positioned close enough to the rotor for accurate displacement detection through the transmission mechanism, while physically isolating it from direct contact with the rotor to prevent damage from touch, winding, and friction.
2Volume of moving object
If the electric pushing rod is designed with a compact structure, then the device size is reduced, but no space is left for wiring which makes wires messy and easily broken
Solution Approach 1:
The end cover is designed with a groove that creates a dedicated wiring channel within the compact motor housing. This utilizes the vertical/dimensional space within the end cover structure rather than horizontal space, allowing wires to be neatly routed and protected without increasing the overall device footprint. The groove provides a protected pathway that prevents wires from being exposed to friction and damage while maintaining compact dimensions.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents wire damage, maintains a clean and organized wiring system, and ensures reliable operation by securing wires and managing static electricity, enhancing the structural integrity and functionality of the electric pushing rod.
Implementation Method 1
Temperature change of the motor can be measured by the temperature sensing member directly touching the body
Implementation Method 2
The electrostatic conductive members are in direct contact with the metallic sleeve of the body to guide out static electricity, preventing the interference of static electricity

AI summary
The invention relates to an electric pushing rod with wire protection, which includes a motor, a transmission, a sensor and a wire protector cover. The motor has a body and a shaft. The shaft has a head section and a tail section. Both the head section and the tail section are separately exposed from the body. The transmission is arranged beside the motor. The sensor is disposed correspondingly to the tail section of the shaft and includes a circuit board and conductive wires. The wire protector cover covers the sensor and the tail section of the shaft and is provided with an opening for being passed by the conductive wires. Thereby, the conductive wires are prevented from being broken by touches and friction of the shaft.
