Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices are limited in application range due to their reliance on only one type of terminal, and adapting to different criteria and standards across countries and areas requires dedicated molds, increasing production costs.
Innovation Solution
A terminal assembly comprising a first threaded terminal and a second unthreaded terminal, connected via a hook and clamping arm, allowing for connection with both multi-core and single-core wires, thereby satisfying diverse terminal requirements and reducing mold costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one type of terminal is used in the electrical device, then the device complexity is reduced, but the adaptability to different criteria and standards is limited
Solution Approach 1:
The patent combines both threaded terminal and unthreaded terminal types into a single integrated terminal assembly. The terminal assembly includes a terminal body with both a threaded hole for threaded terminals and a clamping structure for unthreaded terminals, allowing one assembly to fulfill multiple terminal connection functions and adapt to different regional standards.
Solution Approach 2:
The terminal assembly is designed with multi-functionality to accommodate both threaded and unthreaded terminal configurations. By integrating multiple connection methods into a single universal assembly, the invention enables the electrical device to meet diverse terminal standards without requiring separate dedicated assemblies for each standard type.
2Ease of manufacture
If dedicated molds are produced for different terminal types, then the manufacturing precision for each terminal type is improved, but the production cost increases
Solution Approach 1:
The terminal assembly serves as a universal component that can accommodate both threaded and unthreaded terminal types through its integrated design. This multi-functional approach eliminates the need for producing separate dedicated molds for different terminal types, thereby reducing mold investment and production costs while maintaining reliable connection capabilities for various terminal configurations.
Solution Approach 2:
The patent merges the functions of multiple terminal types into a single terminal assembly design. By consolidating both threaded and unthreaded connection capabilities into one assembly type, the invention reduces the number of dedicated molds required, lowering manufacturing costs while preserving the manufacturing precision needed for reliable terminal connections.
3Adaptability or versatility
If a single terminal type is used, then the device structure is simplified, but the application range is limited
Solution Approach 1:
The terminal assembly is designed as a universal component capable of supporting both threaded and unthreaded terminal connections. This multi-functional design expands the application range of the electrical device to meet different regional standards and wire types, while the integrated structure keeps the overall complexity manageable through unified design elements.
Solution Approach 2:
The invention combines multiple terminal connection methods within a single terminal assembly structure. By merging threaded and unthreaded connection capabilities into one unified assembly, the patent broadens the application range without proportionally increasing structural complexity, as both connection types share common structural elements and mounting interfaces.

AI summary
Embodiments of the present disclosure provide a terminal assembly for an electrical device and an electrical device comprising the same. The terminal assembly comprises: a first terminal comprising a terminal seat and a screw in a threaded connection with the terminal seat, a cavity for receiving a wire being formed in the terminal seat; and a second terminal, comprising: a body provided with a hook thereon, wherein the first terminal is adapted to be connected with the second terminal via the hook; and a clamping arm with one end connected with the body and the other end being a free end adapted to cooperate with the body for clamping the wire. Such terminal assembly can provide two different types of terminals to adapt to criteria in different countries and areas, and thus can broaden the application range of the product.
