Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a magnetic field is used to levitate the speaker, then the speaker can vibrate without contact with external objects, but it becomes difficult to control the height of the levitating speaker
Solution Approach 1:
The patent introduces a magnetic field as an intermediary force to enable contactless levitation of the speaker. The magnetic field acts as a mediator between the speaker and external objects, allowing the speaker to float without physical contact while still enabling controlled height adjustment through magnetic field manipulation.
Solution Approach 2:
The patent utilizes changes in magnetic field parameters (strength, distribution, polarity) to control the levitation height of the speaker. By adjusting magnetic field parameters, the system can precisely control the speaker's position in the air while maintaining contactless operation.
2Length of stationary object
If the device structure is simplified for compact design, then vertical length is reduced, but structural stability for height control may be compromised
Solution Approach 1:
The patent employs a nested structure where the magnetic field generation components are integrated within a compact housing. The elevation member, transmission member, and support member are arranged in a nested configuration that minimizes vertical space while maintaining structural integrity and stability for height control.
Solution Approach 2:
The patent transitions from a vertical arrangement to a more distributed spatial configuration, utilizing horizontal and angular dimensions to achieve the same functional goals. The transmission member rotates along a circumference rather than moving strictly vertically, allowing compact vertical design while preserving control stability.
3Measurement precision
If a transmission member rotates along a circumference to control elevation, then height control precision is improved, but the device complexity increases
Solution Approach 1:
The patent designs the transmission member to serve multiple functions: it rotates along a circumference for precise height control, supports the elevation member, and integrates with the magnetic field generation system. This multi-functionality reduces the need for separate components, thereby limiting the increase in overall device complexity despite the enhanced precision mechanism.
4Measurement precision
If the motor drives the transmission member continuously for height adjustment, then positioning accuracy is maintained, but the driving load on the motor increases
Solution Approach 1:
The patent implements periodic or intermittent motor operation rather than continuous driving. The motor activates only when height adjustment is needed, maintaining positioning accuracy through controlled periodic motion. This approach significantly reduces the overall driving load and energy consumption while preserving the ability to achieve precise positioning when required.
