Design Blueprint: Pool Gate Latch Height
Year: 2026
Type: article
Abstract: Design blueprint derived from the source paper (DOI 10.5281/zenodo.24121683): A gate between a garden and a swimming pool must be operable by every adult and by almost no young child, and the dimension that decides the matter is latch height. This study models a child's chance of reaching and operating a latch as a logistic function of height, with a midpoint of 1.38 m for five-year-olds and 1.43 m for six-year-olds, both stated values, and asks where the chance falls below one percent. At 1.35 m a five-year-old still succeeds 66.08 percent of the time; at 1.5 m the figure is 6.5 percent. The one-percent level for five-year-olds is reached at 1.587 m, and for six-year-o 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.
