Solution Overview

Problem

Existing linear motor supports suffer from non-uniform stress and deformation due to lack of mutual restraint, leading to assembly difficulties and potential breakage, requiring screw locking which complicates installation.

Innovation Solution

A support structure comprising top covers, side plates, and a mounting base connected to form a closed ring, with integrated components allowing for screwless assembly and enhanced stability through insertion of pillars and elastic connectors, and silicon steel sheets to enhance magnetic field utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a semi-enclosed frame structure is used for the linear motor support, then the structure is simpler to manufacture, but the top cover and support side plates are prone to deformation or breakage due to non-uniform stress distribution

Engineering Contradiction:

Improveease of manufactureVSAvoidreliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent merges the top cover, support side plates, and mounting base into an integrated enclosed frame structure where the top cover is surrounded by support side plates at both ends and connected to the mounting base, forming a unified structural system that distributes stress uniformly across all components

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If screw locking is used to secure the stator core on the mounting base, then the connection is more reliable, but the installation process becomes more complex and difficult

Engineering Contradiction:

ImprovereliabilityVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the traditional screw locking mechanism with a snap-fit connection system where the stator core includes positioning protrusions that engage with corresponding positioning grooves on the mounting base, enabling tool-free assembly while maintaining secure mechanical connection

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If the top cover, support side plates and mounting base are not mutually restrained, then the assembly process is simpler, but the components are stressed non-uniformly leading to deformation or breakage

Engineering Contradiction:

Improvedevice complexityVSAvoidstrength

Core Design Contradiction:

Device complexityVSStrength

Solution Approach 1:

The patent creates an equipotential stress distribution system where the enclosed frame structure ensures that the top cover, support side plates, and mounting base are all equally restrained and share the mechanical loads uniformly, preventing stress concentration on any single component

Inventive Principle:

Principle #12Equipotentiality

AI summary

A support structure for a linear motor includes top covers, side plates, a mounting base and a stator core. The top covers, the side plates and the mounting base are integrally connected to form a closed ring, and a semi-enclosed structure is eliminated, such that the top covers, the side plates and the mounting base form a more stable connection structure and are mutually restrained and stressed more uniformly, thus improving the safety in production and assembly; moreover, the stator core and magnets are assembled by insertion and do not need to be locked with screws, such that assembly is easier.
