Compact Motor Connector Module with Right-Angle Flat Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motor designs for power window devices are hindered by the size of the connector module, which extends sideways and increases the overall motor size, making it difficult to arrange in various locations.
Innovation Solution
A motor design that incorporates a connector module with a flat relay electrically connecting the control circuit substrate and connector unit at a right angle, allowing for a compact configuration and reducing the motor's size by eliminating unnecessary extensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connector module is arranged to extend sideward from the motor, then the connector unit and control circuit substrate can be electrically connected, but the motor size is enlarged
Solution Approach 1:
The relay is arranged at a right angle relative to the control circuit substrate, changing the spatial dimension of electrical connection from planar extension to vertical stacking. This allows the connector module to be inserted along the insertion direction without sideward extension, reducing motor size while maintaining electrical connectivity between the connector unit and control circuit substrate through the vertically arranged relay
2Volume of moving object
If the relay is arranged at a right angle relative to the control circuit substrate, then the motor size is reduced, but the electrical connection path becomes more complex
Solution Approach 1:
The relay integrates multiple functions into a single component: it provides electrical connection between the connector unit and control circuit substrate, enables signal transmission for motor control, and allows compact vertical arrangement. By merging these functions into one vertically arranged component, the patent reduces motor size while avoiding the need for separate complex connection paths

AI summary
A motor including a motor case, a rotary shaft, and a connector module. The rotary shaft is accommodated and rotated in the motor case. The connector module includes a connector unit, which is electrically connected to an external device and supplies power, and a flat control circuit substrate, which controls rotation of the rotary shaft. The motor case includes an insertion opening into which the connector module is inserted along an insertion direction. The connector module includes a connector housing, which accommodates at least part of the control circuit substrate, and a flat relay, which electrically connects the control circuit substrate and the connector unit and is arranged at a right angle relative to the control circuit substrate.
