Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws and screw holes are used to fasten electronic devices, then the connection strength is sufficient, but the installation time and material costs increase
Solution Approach 1:
The patent removes screws and screw holes from the fastening system, extracting the time-consuming and costly elements while replacing them with a friction-based rotational mechanism that achieves secure fixation without traditional fasteners
Solution Approach 2:
The invention replaces the screw-thread mechanical fastening system with a friction-based rotational positioning system, where the electronic device is secured through friction between contact surfaces rather than threaded engagement
2Strength
If screws and screw holes are used to fasten electronic devices, then the connection is secure, but the material costs increase
Solution Approach 1:
The patent eliminates screws and corresponding screw holes from the design, removing the material requirements for these fastening components and reducing overall material costs while maintaining connection integrity through alternative friction-based mechanisms
3Productivity
If a rotational mechanism is used for fastening, then the installation speed increases, but the device complexity increases
Solution Approach 1:
The patent introduces a rotational mechanism that allows the electronic device to be installed by rotating into position, transforming a static fastening approach into a dynamic one that enables quicker installation while the friction-based securing method keeps the overall structure relatively simple
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
Enables rapid and secure installation and removal of electronic devices, reducing material costs and assembly time while preventing device damage during handling, as the rotational mechanism provides stable and friction-assisted positioning without the need for screws.
Implementation Method 1
the buffer unit contacts the electronic device fastening set... When the electronic device rotates relative to the main body, the buffer unit contacts the electronic device fastening set

AI summary
A computer host case structure for fastening at least one electronic device is disclosed. The computer host case includes a main body, two pivot structures, an electronic device fastening set, and two pivot axes. The pivot structure includes a notch. Two pivot axes are used for pivotally connecting to the pivot structure. The electronic device fastening set is fastened to at least one electronic device. When the electronic device fastening set rotates to a specific angle relative to the main body via the pivotal connection between the pivot axes and the pivot structures, the two pivot axes respectively enter the notches of the two pivot structures.
