Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw connections or material bonding processes are used to connect fluid lines to containers, then reliable fluid-tight connections are achieved, but assembly effort and manufacturing complexity increase significantly
Solution Approach 1:
The connection system is divided into two separate components: a wall element with integrated sealing structure and a connecting element with complementary sealing surfaces. This segmentation eliminates the need for complex bonding processes while maintaining reliable fluid-tight connections through mechanical insertion and sealing surface contact.
Solution Approach 2:
The sealing function is merged directly into the wall element by providing a flat bearing surface and sealing geometry within the wall element itself, rather than requiring separate sealing components or bonding materials. This integration simplifies the overall assembly process while ensuring reliable sealing.
2Stability of the object's composition
If multiple assembly steps including positioning and securing are used to attach nozzles to containers, then stable connections are achieved, but assembly time and labor costs increase
Solution Approach 1:
The wall element is pre-configured with the sealing structure and geometric features during manufacturing, so that during assembly only a single insertion and rotation movement is required. The preliminary preparation of the sealing surface and locking geometry eliminates the need for multiple positioning and securing steps, reducing assembly time while maintaining connection stability.
3Reliability
If conventional connection methods requiring several work steps are used, then secure fluid lines to containers are achieved, but manufacturing costs increase
Solution Approach 1:
The connecting element is designed to self-align and self-seal during the single movement assembly process. The geometric features of the connecting element automatically position themselves relative to the wall element, and the sealing surfaces engage automatically upon insertion and rotation, eliminating the need for additional securing operations and reducing manufacturing costs.
4Reliability
If traditional fittings requiring screwing or flange attachment are used, then reliable container connections are achieved, but assembly simplicity decreases
Solution Approach 1:
The connection process transitions from static multi-step operations (screwing, flange attachment) to a dynamic single-movement operation (insertion followed by rotation). The rotational movement dynamically engages the sealing surfaces and locking features, achieving reliable connection in one continuous action that is simpler to perform than traditional methods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces assembly effort by allowing a single movement sequence for mounting, enabling quick and efficient fluid-tight connections without gluing or welding, and can be used in various applications such as tanks, vessels, and containers.
Implementation Method 1
The first sealing surface can, for example, be designed as a radially circumferential groove with an O-ring. The axially directed contact pressure can, for example, be generated by a connecting element that has contact ramps.
