Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the linear motor is designed to vibrate in the vertical direction (Y-axis), then the vibration feedback capability is improved, but the size in the Y-axis direction increases and component placement flexibility is reduced
Solution Approach 1:
The patent reorients the linear motor's vibration direction from the conventional horizontal (X-axis) to vertical (Y-axis) direction by changing the placement orientation. The motor structure is designed to accommodate vertical vibration through proper arrangement of the magnet module, coil module, and swinging elements, enabling the motor to deliver vibration feedback in the Y-axis direction while maintaining a compact form factor that does not significantly increase the overall Y-axis dimension of the device.
Solution Approach 2:
The patent employs swinging elements (swinging arms or elastic elements) that can dynamically move between horizontal and vertical positions. These swinging elements connect the support base to the circuit mechanism, allowing the system to adapt its configuration. When activated, the swinging elements enable vertical vibration motion while maintaining structural flexibility, thus achieving Y-axis vibration without permanently increasing the device's Y-axis footprint.
2Ease of operation
If the linear motor is designed to vibrate in the vertical direction (Y-axis), then the vibration feedback capability is improved, but the component placement flexibility and circuit design flexibility are reduced
Solution Approach 1:
The patent designs the swinging elements to serve multiple functions: they act as mechanical connectors between the support base and circuit mechanism, provide structural support, enable vertical vibration motion, and offer placement flexibility through their ability to swing between positions. This multi-functionality allows the same component to address several design requirements simultaneously, maintaining component placement flexibility while achieving vertical vibration capability.
Solution Approach 2:
The dynamic swinging capability of the swinging elements allows the system to adapt its configuration based on operational requirements. The swinging arms or elastic elements can move between horizontal and vertical orientations, enabling the circuit mechanism to be positioned flexibly while still achieving vertical vibration when needed. This dynamic adaptability preserves design flexibility without compromising vibration performance.
3Length of moving object
If the linear motor size in the Y-axis direction is reduced, then the device can be made thinner, but the vibration performance in the vertical direction is compromised
Solution Approach 1:
The patent employs thin elastic elements as swinging components that provide both mechanical flexibility and structural support. These thin elastic elements maintain the compact Y-axis dimension of the device while still enabling effective vertical vibration transmission. The elastic nature of these thin components allows them to flex during vibration cycles, transmitting vibrational energy efficiently without requiring significant Y-axis space.
Solution Approach 2:
The dynamic swinging motion of the lightweight swinging elements amplifies the vibration effect. By utilizing the natural oscillation and swinging motion of these elements, the system achieves enhanced vibration performance without proportionally increasing the motor size. The dynamic motion allows small displacements to generate noticeable vibration feedback, maintaining strong vibration performance within a compact Y-axis footprint.
