Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex procedures and additional tools are used to install and remove modules, then secure module fixation is achieved, but user convenience deteriorates and device complexity increases
Solution Approach 1:
The tensile element automatically performs the fixation function when the module is inserted. The elastic deformation of the tensile element creates retention force without requiring external tools or complex procedures. The module itself triggers the fixation mechanism through its insertion motion.
Solution Approach 2:
The tensile element transitions from a static fixed state to a dynamic elastic deformation state during module insertion, then returns to its original shape to provide continuous retention force. This dynamic behavior enables automatic securing without manual intervention.
2Reliability
If additional tools and guiding components are used for module installation, then secure module fixation is achieved, but manufacturing cost increases
Solution Approach 1:
The guiding components and additional tools are completely removed from the system. The tensile element alone performs both the guiding and fixation functions through its elastic properties, eliminating the need for separate guiding components and reducing manufacturing complexity.
Solution Approach 2:
The tensile element serves multiple functions: it acts as a guiding component during insertion, provides retention force through elastic deformation, and maintains secure fixation. This multi-functionality eliminates the need for separate components, reducing manufacturing cost.
3Ease of operation
If tensile elements are used to hold modules, then module fixation is simplified, but the complexity of the tensile element mechanism increases
Solution Approach 1:
The tensile element utilizes changes in its physical state (elastic deformation) to achieve the fixation function. By exploiting the material's elastic properties, the mechanism achieves simple operation without requiring complex structural designs.
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 simple and tool-free module removal, reducing manufacturing costs by eliminating external guiding components and enhancing user convenience while maintaining secure module fixation.
Implementation Method 1
Each of modules is configured to abut against the corresponding tensile element, such that the corresponding tensile element at least partially extends elastically towards the chamber
Implementation Method 2
When the buckle between the first buckling portion of the module and the second buckling portion of the casing is released, the tensile element then releases the potential energy stored and recovers the winding about the shafts. Consequently, the module is pushed out of the casing

AI summary
A server includes a casing, a plurality of tensile elements and a plurality of modules. The casing has an opening and a chamber communicating with each other. The tensile elements are disposed on the casing and at least partially cover the opening. Each of modules is configured to abut against the corresponding tensile element, such that the corresponding tensile element at least partially extends elastically towards the chamber. The modules penetrate through the opening and enter into the chamber in order to fix the modules to the casing.
