'standardly-designed' originates from the combination of 'standardly' and 'designed', where 'standardly' is derived from 'standard', meaning 'a level of quality or attainment', and 'designed' is the past participle of 'design', meaning 'to plan and make decisions about something that is being built or created'.

'standardly' evolved from the noun 'standard', and 'designed' is the past participle form of 'design', which has been used in English since the 14th century.

Initially, 'standard' referred to a flag or banner, but over time it evolved to mean a level of quality or attainment. 'Design' has largely retained its original meaning of planning and creating.
