"Jury-rigged expedients" can be replaced with several other synonyms that can convey the same meaning, such as makeshift solutions, temporary fixes, stopgap measures, and ad hoc solutions. These terms refer to impromptu or temporary measures that are used to address a pressing issue or problem. They are often used when permanent solutions are not available or not feasible. Others may also use terms like quick fixes, band-aid solutions, or patchwork solutions to describe the same concept. All of these synonyms envision a temporary solution that might get the job done but may not be sustainable or long-lasting. Regardless of the terminology, they all emphasize the fact that the solution is only a temporary band-aid rather than a comprehensive fix.
