Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If small internal combustion engines are used to power outdoor equipment, then mechanical output and power are achieved, but environmental harm and inefficiency occur
Solution Approach 1:
The patent replaces the internal combustion engine (mechanical/chemical system) with an electric motor (electrical system). The electric powerhead uses an electric motor coupled with a lithium-ion battery to provide mechanical output, eliminating combustion processes and associated environmental harm while improving energy efficiency.
2Object-generated harmful factors
If electric motors are designed to replace internal combustion engines, then environmental friendliness and efficiency improve, but compatibility with existing equipment mounting patterns may worsen
Solution Approach 1:
The mounting assembly is designed with opening patterns that match standard vertical shaft engine mounting configurations. This allows the electric powerhead to serve multiple functions: it can be installed in existing outdoor power equipment designed for internal combustion engines while maintaining zero emissions and high efficiency.
3Reliability
If a mounting assembly with multiple openings is used for secure attachment, then reliability of mounting improves, but device complexity increases
Solution Approach 1:
The mounting assembly is segmented into distinct functional elements: a mounting plate with multiple openings for attachment, and a mounting insert with corresponding openings. This segmentation allows each component to be optimized for its specific function while collectively providing secure mounting without excessive overall complexity.
