NASA Positive Connection (Robuste and simple)

Here are some photos as well as the stages of the different states of the design:Phase 1: Not connectedPhase 2: At the limit, rod descending. A shock is produced to position the parts.Phase 3: The mirrors are connected and positioned with the desired compression force.I'd like to point out that this project still requires an industrialization phase before it can be produced. It is more of a concept at this stage. I have done my best to define its shapes, but there are still specific data missing to determine all the dimensions, such as the size of the springs, etc. To obtain 9N of shock, it's necessary to know the exact force required for locking in order to dimension the accelaration distance of the assembly for the shock. If needed, I am available for further industrialization or to answer any questions.Responses to questions:Question: Written justification explaining why the latch will produce the desired preload and how these forces have been calculated.Response: The mechanics of this design can accommodate a lock between 50 and 200N. However, it's crucial to size the compression spring based on the exact desired force.Question: Why an acceleration of 250G will not accidentally trigger the device.Response: Based on the spring's force and the rod's mass, it is necessary to select a spring that exceeds the maximum effort that this acceleration could produce. However, it's essential to know the precise locking force to size the spring and the slope that exerts pressure on the pin correctly. The trigger distance is also a significant factor in preventing any unintentional triggering.Question: The device can operate between -10°C and 60°C and survive temperatures ranging from -60°C to 100°C.Response: There's no issue concerning the temperatures; the materials used can operate flawlessly within these ranges. However, it will be necessary to select the spring's coil count, its diameter, and its material to match the desired pressure tolerances for the entire system.PS: I'd like to apologize for the error in positioning the concept on the CAD (Miror fixation), I didn't have time to reposition and resize the whole thing, but if necessary I'll be happy to help.
