Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fastening devices are used to secure oxygen concentrators, then the containers can be fixed, but the fastening process becomes intricate and requires tools, reducing ease of operation
Solution Approach 1:
The fastening device is divided into distinct functional segments: a receiving body for holding the concentrator, a securing device with latching mechanism for fastening, and a fixing device for mounting. This segmentation allows each component to be optimized independently and simplifies the overall operation by distributing functions across modular elements.
Solution Approach 2:
The latching mechanism is designed to automatically engage and secure the oxygen concentrator without requiring manual intervention or external tools. The mechanism self-actuates through the insertion motion itself, transforming the simple act of placing the concentrator into the receiving body into the fastening action, thereby eliminating the need for separate fastening operations.
2Productivity
If traditional fastening devices are used, then containers can be secured, but the process is time-consuming and not quick, reducing productivity
Solution Approach 1:
The receiving body is pre-configured with the securing device and latching mechanism in a ready state. The fixing device with mounting profile is pre-positioned for rapid attachment to standard rails. When the oxygen concentrator is inserted, the latching mechanism is already positioned to automatically engage, eliminating the need for sequential fastening steps and reducing the time required for securement.
Solution Approach 2:
The fastening process skips traditional multi-step procedures such as aligning separate fastening components, inserting bolts, or tightening fasteners. Instead, the single motion of inserting the concentrator into the receiving body rushes through the entire fastening sequence, with the latching mechanism completing the securing action in one continuous motion.
3Adaptability or versatility
If traditional fastening devices are used, then containers can be fixed, but they lack versatility for attaching to different surfaces like rails or stretchers, reducing adaptability
Solution Approach 1:
The fixing device incorporates a mounting profile designed to interface with standard rails, while the receiving body can be mounted on various surfaces including stretchers and vehicle walls. This universal design allows the same fastening device to be adapted to multiple mounting locations and surface types without requiring device-specific modifications, achieving multi-functionality across different application scenarios.
Solution Approach 2:
The mounting system is designed with dynamic adaptability, allowing the receiving body to be positioned and secured at various locations along the longitudinal direction. The fixing device can accommodate different mounting heights and orientations, providing flexibility in installation while maintaining a relatively simple overall structure through standardized interface elements.

AI summary
A fastening device for fastening an oxygen concentrator has a receiving body extending in a longitudinal direction. The receiving body has a facing side facing the oxygen concentrator and a facing-away side facing away from the oxygen concentrator. The receiving body has at least one receiving element on the facing side and at least one fixing device on the facing-away side. A securing device is arranged on the receiving body, wherein the securing device has a latching mechanism.
