Cord Protection Connector for One-Step Appliance Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection of electrical connectors in household appliances, such as irons, requires a specific and time-consuming assembly operation that is not ergonomic, leading to inefficiencies in the assembly process.
Innovation Solution
A protective element integral with the cord, which includes a connector, is designed to facilitate the electrical connection directly during assembly, allowing for a single operation that simplifies the assembly process by integrating the connector into the protection element, such as a molded plastic sheath with a hinge and fixing flange, ensuring proper positioning and immobilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are manually connected to pins in a separate operation, then electrical connection is achieved, but assembly time increases and ergonomics deteriorate
Solution Approach 1:
The protective element is merged with the connector to form a single integrated component. This allows the protective element to be installed in the opening and the electrical connection to be made simultaneously in one operation, eliminating the need for a separate manual connection step and thereby reducing assembly time while maintaining reliable electrical connection.
2Reliability
If connectors are manually connected to pins in a separate operation, then electrical connection is achieved, but assembly ergonomics worsen
Solution Approach 1:
By combining the protective element and connector into one integrated component, the assembly operation is simplified to a single intuitive installation action. This improves ergonomics by reducing the number of discrete steps and manual manipulation required, while the integrated design ensures proper alignment and reliable electrical connection without requiring complex manual connection procedures.
3Productivity
If the protective element is integrated with the connector, then assembly operation is simplified, but device complexity increases
Solution Approach 1:
The protective element and connector are merged into a single integrated component that can be installed in one operation, improving productivity. The integration is achieved through design features such as the connector being formed as part of the protective element or vice versa, with positioning features that ensure proper alignment. This unified design simplifies the assembly process while the internal integration maintains manageable device complexity.
