Motor Terminal Substrate Layout for Variable Terminal Pitch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible substrates require separate substrates for motors with different terminal pitches, necessitating multiple designs and increasing complexity and cost.
Innovation Solution
A substrate design with intersecting holes in the fixing sections allows for flexible alignment and fixation of motors with varying terminal pitches, enabling a single substrate to accommodate multiple motor types by inserting terminals through specific holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate substrates are used for motors with different terminal pitches, then each motor type can be precisely accommodated, but the number of substrate designs increases and complexity increases
Solution Approach 1:
The substrate is designed with multiple holes in the first fixing section, allowing a single substrate to accommodate motors with different terminal pitches. The first terminal can be inserted through different holes depending on the motor type, making the substrate universal for multiple motor variants while maintaining precise terminal pitch accommodation.
Solution Approach 2:
The first fixing section is segmented into multiple holes arranged at different positions. This segmentation allows selective insertion of the first terminal through appropriate holes to match different terminal pitches, enabling one substrate to serve multiple motor types without requiring separate substrate designs for each pitch variation.
2Reliability
If multiple substrate designs are created for different motor types, then each motor can be precisely fixed, but the manufacturing cost and design complexity increase
Solution Approach 1:
By incorporating multiple holes in the first fixing section, the substrate becomes a universal component that can reliably fix various motor types with different terminal pitches. This eliminates the need for multiple specialized substrate designs, thereby reducing manufacturing costs while maintaining reliable fixation for each motor type.
3Ease of manufacture
If a single substrate design is used for all motor types, then manufacturing is simplified, but accommodation of different terminal pitches becomes difficult
Solution Approach 1:
The first fixing section is divided into multiple holes positioned to accommodate different terminal pitches. This segmentation allows the single substrate design to adapt to various motor types by selecting the appropriate hole for terminal insertion, thereby maintaining both manufacturing simplicity and terminal pitch adaptability.
Solution Approach 2:
The substrate provides dynamic adaptability through multiple hole options, allowing the configuration to be adjusted based on the specific motor type being installed. This enables a single static substrate design to dynamically accommodate different terminal pitches through selective terminal insertion paths.

AI summary
A substrate includes a first fixing section and a second fixing section. On the first fixing section, a first terminal of a pair of plate-shaped terminals protruding from a motor is fixed. On the second fixing section, a second terminal of the pair of terminals is fixed. The first fixing section includes a first hole and a second hole. The first hole extends in a second direction, intersecting a first direction extending from the first terminal toward the second terminal. The second hole extends in the second direction, and is located adjacent to the first hole, on an opposite side of the second terminal with respect to the first hole, in the first direction. The first terminal is inserted through one of the first hole and the second hole.
