Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional clock oscillator structure without shock absorption is used, then the device complexity is low, but the shock absorption performance is poor and the output frequency becomes unstable under external vibration
Solution Approach 1:
The patent introduces a shock-absorbing material layer as an intermediary component between the resonator and the base. This layer acts as a mediator that isolates the resonator from external vibrations transmitted through the base, thereby stabilizing the output frequency without fundamentally changing the overall oscillator structure
Solution Approach 2:
The shock-absorbing material layer is implemented as a thin film or layered structure with flexible shock-absorbing properties. This thin film approach provides effective vibration isolation while maintaining a compact device profile and minimizing increases in device complexity
2Reliability
If the shock-absorbing material layer thickness is increased to improve shock absorption, then the shock absorption performance improves, but the device size increases
Solution Approach 1:
The patent employs a shock-absorbing material layer in the form of a thin film with optimized thickness. This thin film structure provides effective shock absorption while minimizing the increase in device size, achieving a balance between protection performance and compact dimensions
Solution Approach 2:
The patent optimizes the thickness parameter of the shock-absorbing material layer to achieve the desired shock absorption performance. By carefully selecting and tuning this parameter, the design achieves effective vibration isolation while maintaining a compact device size suitable for small-scale applications
3Reliability
If high-strength and high-toughness materials are used for the shock-absorbing layer, then the reliability and shock absorption improve, but the manufacturing cost increases
Solution Approach 1:
The patent utilizes composite material structures for the shock-absorbing layer that combine high strength and toughness properties. These composite materials provide superior mechanical performance while being amenable to cost-effective manufacturing processes, balancing reliability requirements with manufacturing considerations

AI summary
A clock oscillator, a clock oscillator production method and use method, and a chip including the clock oscillator are provided. The clock oscillator includes a resonator, a shock-absorbing material layer, and a base, and at least a part of the shock-absorbing material layer is located between the resonator and the base. In the clock oscillator, the shock-absorbing material layer is added between the resonator and the base, and the shock-absorbing material layer can effectively prevent a mechanical wave from being conducted between the base and the resonator, so that the resonator is protected from external vibration. This can ensure, when there is external vibration, that an output frequency of the resonator is not deteriorated and improve shock absorption performance of the clock oscillator.
