Relational vulnerability as a design entry point: activating community connections through micro-prototypes

Research on vulnerability in community contexts has largely centered on physical infrastructure or gaps in public services. This study focuses instead on relational vulnerability—the decline of everyday social ties, which remains less visible but significantly shapes how communities collaborate. The research proposes treating vulnerable relationships as a primary focus of design. It introduces a method based on micro-prototypes—small, embedded interventions aimed at making social connections more visible, easier to initiate, and possible to sustain. Fieldwork in a pilot community revealed three relational design mechanisms: perception, which helps residents notice missing or silent connections; triggering, which invites informal and non-obligatory interaction; and sustaining, which supports continuity through recurring, low-effort social cues. Rather than solving defined problems, these relational strategies help open up space for encounter, attention, and emotional engagement in daily life. The findings show that design can quietly help bring inactive forms of collaboration back to life.
