Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional reciprocating mechanisms (cams, push rods) are used to convert rotational motion to reciprocating motion, then the device can achieve reciprocating action, but the device requires awkward shaping and has limited stroke length
Solution Approach 1:
The patent replaces traditional mechanical reciprocating mechanisms (cams, push rods) with a direct linear motor that generates reciprocating motion through electromagnetic force. This substitution eliminates the need for complex mechanical linkages that require awkward shaping, allowing for a more compact and efficiently shaped device while achieving extended stroke length through direct linear actuation rather than mechanical conversion.
2Power
If traditional reciprocating mechanisms are used, then reciprocating action can be achieved, but power utilization is inefficient and drive force is weak for portable arrangements
Solution Approach 1:
The patent replaces mechanical reciprocating mechanisms with a linear motor that directly generates the required reciprocating force. This eliminates mechanical transmission losses associated with cams and push rods, improving power utilization efficiency. The linear motor can deliver higher drive force in a compact form factor, making the device suitable for portable applications while maintaining efficient energy conversion from electrical to mechanical form.
3Force
If traditional reciprocating mechanisms are used, then reciprocating motion can be generated, but the ascending and descending stroke forces are asymmetrical
Solution Approach 1:
The patent replaces mechanical reciprocating mechanisms with a linear motor that can independently control the force applied during ascending and descending strokes. By directly actuating the stimulation body along the longitudinal axis without mechanical conversion, the system achieves symmetrical force application in both directions of motion, eliminating the asymmetry inherent in cam-based mechanisms while reducing overall device complexity.
