[0002] In many engineering applications, such as aerospace equipment, deep-sea exploration devices, and building maintenance equipment, electromechanical equipment and components often need to be installed in extremely confined spaces. Traditional electromechanical model design methods typically focus on functional implementation, while rarely considering the numerous constraints imposed by the limited space, such as irregular spatial geometry, heat dissipation difficulties, narrow maintenance passages, and insufficient space for piping and wiring. This can easily lead to interference, unstable performance, or even malfunction of the designed electromechanical model during actual assembly and operation, as well as mismatches during on-site installation of electromechanical equipment.
