Solution Overview
Problem
Conventional slide devices suffer from cumulative tolerances, vibration, reduced positional repeatability, high production inefficiency due to jig limitations, fastener breakage, and increased temperature and size due to bulky rail designs, especially under high loads.
Innovation Solution
A slide apparatus with a track body, primary and secondary modules forming a linear motor, where the secondary module is integrated with the slider's housing and uses embedded rail elements and radiating fins to reduce size and temperature, and eliminate fastener issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional motor-driven slide devices use a bulky rail design, then the device can support load, but the volume and weight of the device increase
Solution Approach 1:
The patent combines the rail function with the housing structure by forming recessed spaces directly in the housing to receive linear motors, eliminating the need for separate bulky rails. The housing serves dual purposes as both structural support and motor mounting platform, reducing overall device volume while maintaining load capacity.
Solution Approach 2:
The patent repositions linear motors vertically within recessed spaces of the housing rather than mounting them horizontally on external rails. This dimensional reconfiguration reduces the horizontal footprint of the device while maintaining the necessary force generation capability for load support.
2Reliability
If conventional linear motors use fasteners to fix the mover onto the supportive body, then the motor can be secured, but the fasteners may breakage under acceleration or braking, reducing service life
Solution Approach 1:
The patent integrates the mover directly into the housing structure by forming recessed spaces in the housing that receive and secure the linear motors. This integration eliminates separate fasteners and creates a unified structure where the housing itself provides the securing function, preventing fastener breakage under dynamic loads.
Solution Approach 2:
The patent replaces the mechanical fastening system with an integrated structural design where the housing's recessed spaces provide both mounting and securing functions. This substitution eliminates the weak link of fasteners under high acceleration and braking forces.
3Power
If conventional linear motors are operated at high load, then the motor can drive the device, but the temperature of the device rises significantly
Solution Approach 1:
The patent integrates thermal management functionality into the housing structure by incorporating heat dissipation fins directly on the housing surfaces that contact the linear motors. This combination of structural support and thermal management in a single component allows high-power operation without significant temperature rise.
Solution Approach 2:
The patent introduces heat dissipation fins as an intermediary thermal management component between the linear motors and the external environment. These fins increase the surface area for heat transfer, acting as a thermal mediator that allows high-power operation while controlling temperature rise.
4Speed
If conventional slide devices use screw shafts to drive the sliding carrier, then the carrier can move linearly, but cumulative tolerances and vibration occur, reducing positional repeatability
Solution Approach 1:
The patent replaces the mechanical screw shaft drive system with linear motors that directly generate linear motion through electromagnetic forces. This substitution eliminates the cumulative tolerances and vibration inherent in screw shaft mechanisms, achieving high positional repeatability and smooth linear motion without mechanical intermediaries.

AI summary
A slide apparatus includes a track body, at least one primary module, and a slider provided therein with a secondary module. The track body defines a recessed space therein, and the primary module is installed in the recessed space. The slider is slidably mounted on the track body and has a housing located in the recessed pace of the track body. The housing is provided with at least one channel in which the secondary module is located. The channel of the housing, which opens out at a bottom opening facing to a bottom of the track body, serves as a jig to facilitate the secondary module formed integrally with the housing of the slider. The secondary module works with the primary module to constitute a linear motor, which enables the slider to move linearly along the track body.
