Designing separation and uplift: structural problem-solving in brassiere design, 1890s–1970s
Kristina ShinPurpose
Breast separation and uplift are frequently cited objectives in brassiere design, yet they are rarely examined as explicit structural design mechanisms within textile and apparel research. Existing studies typically address these outcomes indirectly through evaluations of comfort, fit, pressure distribution or anthropometric change. This study aims to examine how breast separation and uplift have been conceptualized and addressed as structural design problems within US brassiere patents filed from the 1890s through the 1970s.
Design/methodology/approach
A patent-based historical analysis was conducted using a corpus of 1,671 US brassiere patents. Patent drawings and descriptions were interpreted as records of design intent rather than evidence of validated product performance. Through an interpretive qualitative analysis, patented constructions were examined to identify recurring structural design principles used to organize breast support.
Findings
Despite considerable variation in form and materials, brassiere patents repeatedly use five recurring structural design principles to achieve separation and uplift. These approaches organize breast support through spatial partitioning, suspension, and redistribution of support forces rather than through uniform compression alone. The recurrence of these structural design principles across the patent record indicates structural logic underlying bra design innovation prior to the widespread standardization of underwire-supported bras.
Originality/value
This study contributes to apparel design scholarship by proposing a conceptual classification framework comprising five recurring structural design principles for breast separation and uplift in historical brassiere design. The study further demonstrates how patent archives can be used to reconstruct the structural reasoning underlying garment construction.
