Service robots are widely deployed to address labor shortages and improve service quality, yet many still fail in practice. Most research has focused on the positive, overlooking why they fail. To address this gap, our study examines service robot failures from a service design perspective, focusing on design features. To validate this, we conducted a systematic literature review of 863 studies and selected 34 as our data sample. We identified 17 robot design features across three service design aspects and proposed an integrated framework that explains how these features lead to service failures. Theoretically, this study provides a framework for explaining service robot failures from a service design (S-D Logic) perspective, addressing a gap in HRI and service design research. In practice, this study offers actionable guidance for practitioners on improving the design of service robots, their human-robot interaction, and their system integration in real-world service environments.
