Design Blueprint: Deadbolt Throw
Year: 2026
Type: article
Abstract: Design blueprint derived from the source paper (DOI 10.5281/zenodo.24121578): A deadbolt is sold by its throw, the distance the bolt travels into the frame, yet what a household needs is resistance to the frame splitting around the strike. This study models that resistance from stated assumptions: a steel bolt of 11 mm by 20 mm section has a shear capacity near 61,600 N and never governs, while the timber frame around the strike pocket is modelled as failing at F = 700 + 330 e^0.8 newtons, where e is the engagement depth in millimetres after a 4 mm allowance for door gap and strike recess. A standard 25 mm throw then resists 4470 N and delays entry by about 3.99 minutes Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
