Mechanical Fastener Designs for Use in the Microassembly of 3D Microstructures
Bibliographic record
Abstract
This paper describes micro-mechanical fastener designs used to create joints between surface micromachined micro-parts. This is part of ongoing research to develop a general microassembly system capable of assembling various types of microstructures. The microassembly system is based on sequential robotic operations and the use of a microgripper. Two new joint designs referred to as ‘key-lock’ joints and ‘inter-lock’ joints are introduced. Key-lock joints are created by the insertion of a ‘key’ on one micro-part, into a mating slot on another micro-part. By translating the first micro-part within the other, after the key is inserted, it becomes locked into position. Inter-lock joints are created by the perpendicular insertion of one micro-part with a slit, into another micro-part with a slit. The slits create an interference fit and are permanent once the micro-parts are joined. The design of these joints and the experimental results are detailed. In addition, ongoing work involving recent ‘snap-lock’ joint fastener designs is described. This includes an example of a 3D micro-transformer and a stacked microstructure. These various micro-mechanical fasteners demonstrate a number of ways in which micro-parts can be assembled into 3D microstructures.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
