The technological innovation systems (TIS) framework is one of the dominant perspectives in transitions studies to analyze success conditions and system failures of newly emerging technologies and industries. So far, TIS studies mostly adopted a rather harmonious view on the values of actors and by this were unable to address competition, conflicts and, in particular, battles over diverging directionalities within the system. To empirically assess this potential “harmony fallacy”, we identify values as part of underlying institutional logics of major organizations in the field of modular water technologies in Switzerland by means of 26 expert interviews. We show how logics may condition collaboration patterns and technological preferences. This analysis inspires key conceptual tasks of innovation system analysis, like the identification of system failures, the setting of appropriate system boundaries and the formulation of better policy recommendations.

技术创新系统（TIS）框架是转型研究中分析新兴技术和行业的成功条件和系统失败的主要观点之一。迄今为止，TIS 的研究大多对参与者的价值观采取了一种相当和谐的观点，因此无法解决竞争、冲突，尤其是系统内不同方向的斗争。为了从经验上评估这种潜在的“和谐谬误”，我们通过 26 位专家访谈将价值观确定为瑞士模块化水技术领域主要组织的基本制度逻辑的一部分。我们展示了逻辑如何影响协作模式和技术偏好。这种分析激发了创新系统分析的关键概念任务，
