Methods: We audited 15 initial variables and retained a four-dimensional exploratory space: nominal shell-edge radius (V06), pre-braking trigger distance (V09), translational speed (V11), and commanded deceleration (V12). Latin hypercube samples were filtered by V09 \u2212 V112\/(2V12) \u2265 0. A derived warning margin proxy, I5 = 1 \u2212 [V112\/(2V12)]\/V09, was evaluated with fixed-seed feasibility, distribution, coverage, cluster, coordinate stability, and distance-sensitivity diagnostics. Results: The pooled pre-check acceptance rate was 0.8621. I5 descriptive and distributional stability passed at N = 768\u21921024, but four-dimensional coverage passed in only 10\/30 seeds; no sufficient N was established up to 1024. Natural cluster structure was not detected, exact representative coordinates were seed-sensitive, and selection overlap under an alternative distance definition was 0.53. Two fixed-seed points were therefore retained only as illustrative boundaries. AI-assisted images and legacy Rhino studies were used for qualitative design communication, not as validated realizations of the computation. Conclusions: The evidence-tiered workflow supports traceable exclusion of infeasible combinations and transparent product design translation while preserving explicit limits: no physical safety, usability, manufacturing, or optimality claim is made.<\/jats:p>","DOI":"10.3390\/biomimetics11080578","type":"journal-article","created":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T08:06:16Z","timestamp":1786608376000},"page":"578","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["An Evidence-Tiered Biomimetic Design Space Workflow for the Conceptual Design of Elderly-Care Robots"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-0171-0749","authenticated-orcid":false,"given":"Wangshuang","family":"Zang","sequence":"first","affiliation":[{"name":"School of Design and Innovation, Guangzhou University of Software, Guangzhou 510990, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3776-4330","authenticated-orcid":false,"given":"Congrong","family":"Xiao","sequence":"additional","affiliation":[{"name":"College of Art and Design, Guangdong Baiyun University, Guangzhou 510900, China"},{"name":"Department of X-Cultural Studies, Kookmin University Graduate School, Kookmin University, Seoul 02707, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7607-1572","authenticated-orcid":false,"given":"Dongkwon","family":"Seong","sequence":"additional","affiliation":[{"name":"Department of X-Cultural Studies, Kookmin University Graduate School, Kookmin University, Seoul 02707, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Asgharian, P., Panchea, A.M., and Ferland, F.
