Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for airbag connectors that are miniaturized, lightweight, and flexible, with reduced material usage, while maintaining security and ease of assembly, and capable of being universally usable across different installation situations.
Innovation Solution
A connector system composed of three components: a plug connector, a fixing element, and a locking element, where the contact unit is pre-assembled and integrated subsequently, allowing for flexible assembly and enhanced security through precise positioning and tool-free handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the connector is miniaturized, then the dimensions and weight are reduced, but the assembly complexity and risk of errors increase
Solution Approach 1:
The connector is divided into three separate components: a plug connector, a fixing element, and a locking element. These components can be pre-assembled and stored separately, then easily combined with the contact unit during installation. This segmentation allows for simpler individual components that are less prone to assembly errors while maintaining a compact overall structure.
Solution Approach 2:
The plug connector, fixing element, and locking element can be pre-assembled and prepared in advance before the contact unit is installed. This preliminary preparation reduces the complexity during the final assembly step, as the components are already positioned and ready to be combined with the contact unit, minimizing the risk of assembly errors.
2Weight of stationary object
If the connector is made lightweight with reduced materials, then the weight and environmental impact are reduced, but the reliability and security may be compromised
Solution Approach 1:
By dividing the connector into three functional components (plug connector, fixing element, locking element), each part can be optimized for its specific function using minimal necessary material. This segmentation allows the overall connector to be lightweight while maintaining reliability, as each component contributes specifically to the security and functionality without redundant material.
Solution Approach 2:
The three components (plug connector, fixing element, locking element) work together as an integrated system to provide secure connection. The combining of these simple components creates a reliable connector system that achieves security through functional integration rather than through increased material quantity or weight.
3Adaptability or versatility
If the connector is designed for universal use, then the adaptability increases, but the device complexity increases
Solution Approach 1:
The connector system is designed with standardized components (plug connector, fixing element, locking element) that can be universally applied across different installation situations. The three-component structure allows the same basic design to be used for various contact units and installation locations, achieving universal usability without requiring complex specialized designs for each application.

AI summary
The system has a plug connection (1) for connecting the system to a plug socket, and a fixing element (2) latched to the plug connection. The fixing element fixes a contact unit (4) in an operating position, where the contact unit is electrically connected with an electrical control device. A locking element (3) locks the contact unit in the operating position, and the plug connection with the fixing element. The plug connection, the fixing element and the locking element are formed in a pre-assembling position. The contact unit is received in the system at the pre-assembling position.
