Solution Overview

Problem

Conventional connectors face challenges in connecting linear motors in series due to space constraints caused by the presence of iron cores and coils within the motors, limiting the efficient electrical connection and series arrangement of multiple motors.

Innovation Solution

A connector system comprising a plug holder and a tab holder, positioned in recessed portions on the exterior faces of linear motors, allowing for electrical and physical connection while minimizing space usage by being flush with the motor faces and using a relay connector for additional connections, enabling efficient series connection of multiple linear motors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional connectors are used to connect linear motors in series, then electrical connection is achieved, but space constraints prevent efficient connection due to iron cores and coils inside the motors

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidconnector space requirement
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The connector is repositioned from the traditional side-connection approach to the end-face of the linear motor, utilizing the end-face area that was previously underutilized. This dimensional shift allows the connector to be placed in a space that does not interfere with the internal components (iron cores and coils) of the motor, thereby resolving the space constraint issue while maintaining reliable electrical connection.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The invention uses a tab holder that replicates the electrical connection function traditionally performed by side-mounted connectors. By creating a copy of the connection interface at the end-face position, the system achieves the same electrical connectivity without the spatial constraints of the original connector design.

Inventive Principle:
Principle #26Copying

2Power

If multiple linear motors are connected in series to improve output, then system power increases, but space efficiency decreases due to connector placement

Engineering Contradiction:
Improvesystem outputVSAvoidspace efficiency
Core Design Contradiction:
PowerVSArea of moving object

Solution Approach 1:

By moving the connector to the end-face dimension of the linear motor, the design allows motors to be arranged in series along the motion direction without lateral space occupation. This enables compact series arrangements that maintain high space efficiency while achieving increased system power through multiple motor connections.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The end-face connector design allows for flexible series arrangements where multiple motors can be dynamically configured along the motion direction. The connector placement enables motors to be connected in a compact linear sequence, optimizing the use of available space while maintaining the ability to scale system power by adding more motors in series.

Inventive Principle:
Principle #15Dynamics

3Area of moving object

If connectors are positioned on the exterior face of linear motors, then space efficiency improves, but connection reliability may be compromised

Engineering Contradiction:
Improvespace efficiencyVSAvoidconnection reliability
Core Design Contradiction:
Area of moving objectVSReliability

Solution Approach 1:

The tab holder creates a replicated connection interface at the end-face position that mirrors the functionality of traditional side-mounted connectors. This copying approach ensures that the electrical connection reliability is maintained at the new end-face location, achieving both space efficiency and connection reliability simultaneously.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The tab holder acts as an intermediary element that bridges the electrical connection between series-connected motors at the end-face position. This intermediary structure ensures reliable electrical contact while being positioned in the space-efficient end-face location, resolving the contradiction between position and reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)
