Existing technologies for scaffold construction in
operational railway tunnels present multiple disadvantages, including time
consumption, high cost, and low construction efficiency. To address these
issues, the analytic hierarchy process(AHP)TRIZ multitheory set method
has been utilized to develop a disease treatment trolley scheme. Utilizing AHP,
the critical design elements of the trolley are identified, and their weights
are calculated and ranked as follows: B3>B2 > C3 > B1 > D2 > C1 = C2 > D1 > D4 > D3. Based
on this ranking and the boundary conditions for disease control construction,
eight design elements are prioritized: protective barriers, equipment antislip
and emergency recovery, high strength and stiffness, rapid entry and exit,
compact nonworking size, quick expansion and contraction, fullsection operational platform, and mechanized installation of steel
arch frames. Through pairwise comparison of design elements and construction of
a contradiction matrix, physical and technical contradictions are identified
and addressed using TRIZ theory, which clarifies the principles for resolving
these contradictions. Subsequently, a trolley scheme is designed, and a
prototype is developed. These findings indicate that the AHPTRIZ method provides an objective analysis of functional
requirements and effectively resolves conflicts between design elements,
leading to a trolley that exhibits excellent crosssectional
adaptability.
