Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage devices are fixed in frames of the host casing, then stability and security are improved, but accessibility and ease of maintenance deteriorate
Solution Approach 1:
The patent applies the dynamics principle by transforming the static fixed mounting into a dynamic rotatable mounting system. The modular frame can be rotated between a horizontal position (for stable operation) and a vertical position (for easy removal and maintenance). This allows the system to adapt its state based on operational requirements, combining both stability during use and accessibility during maintenance without requiring separate fixed and removable mounting systems.
2Device complexity
If conventional fixed mounting is used, then structural simplicity is maintained, but maintenance time and complexity increase
Solution Approach 1:
The patent applies segmentation by dividing the mounting system into distinct modular components: the modular frame that holds storage devices, the rotatable connection mechanism, and the retaining buckles. This modular design allows the frame and devices to be easily separated and reassembled, dramatically reducing maintenance time while keeping the overall structure relatively simple and organized.
3Reliability
If screws are used for fixed mounting, then secure attachment is achieved, but risk of losing fastening elements increases
Solution Approach 1:
The patent applies self-service through the retaining buckle mechanism that integrates the fastening function into the modular frame itself. The retaining buckles are permanently attached to the frame and automatically engage with the host casing, eliminating the need for separate loose screws or fastening elements that could be lost. The system performs its own fastening function through the self-contained retaining buckles.
4Ease of operation
If storage devices are made movable and rotatable, then ease of maintenance is improved, but structural complexity and potential instability increase
Solution Approach 1:
The patent applies dynamics by implementing a rotatable connection mechanism that allows the modular frame to move between horizontal and vertical positions. This dynamic capability enables easy maintenance access while maintaining structural integrity through the engineered connection points and retaining buckles, resolving the contradiction between movability and structural complexity.
5Area of stationary object
If storage devices are made rotatable, then operating space is enlarged, but risk of accidental damage increases
Solution Approach 1:
The patent applies preliminary anti-action through the retaining buckle mechanism that prevents the modular frame from rotating beyond the intended vertical position. The retaining buckles engage with corresponding features on the host casing to stop the rotation, preventing the frame from falling or causing accidental damage while still allowing the full range of motion needed to enlarge operating space during maintenance.

AI summary
A rotational retaining mechanism for storage devices allows storage devices to be unlocked quickly in a rotatable way thereby enlarging the operating space in a housing. The rotational retaining mechanism includes a housing, a modular frame for receiving storage devices and a retaining buckle. The housing has a bottom board, a stopping part protruded upwardly from the bottom board, and a front board. The front board has a receiving entry and a pair of pivotal parts respectively formed at two sides thereof. The module frame has a pair of pivotal parts for mounting pivotally with the pivotal parts of the housing, a holding tab, and a clipping part. The holding tab is held by the stopping part of the housing, when the module frame is opened. The retaining buckle is positioned on the housing and clipped with the clipping part when the modular frame is closed.
