Solution Overview
Problem
Existing oscillator designs face challenges in connecting terminals efficiently when a vibrator is positioned between the package terminal and the circuit element, leading to potential wire interference and increased device complexity or size.
Innovation Solution
A vibrator device configuration that includes a base with terminals, a circuit element, a vibrator with a wiring unit, and wires connecting these components, where the vibrator is positioned between the terminals to allow easy electrical connection without wire interference, and a relay substrate on the vibrator to manage wire height and prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vibrator is positioned between the package terminal and the circuit element terminal, then the wire connection becomes complicated and the device size increases, but the electrical connection between terminals can be achieved
Solution Approach 1:
The patent introduces a relay substrate that extends in the planar direction (another dimension) to route wires around the vibrator. Instead of wires crossing over the vibrator in the vertical dimension, the relay substrate provides alternative paths in the horizontal plane, allowing electrical connection without increasing device height while avoiding wire-vibrator interference.
Solution Approach 2:
The relay substrate acts as an intermediary component between the package terminal and the circuit element terminal. It provides intermediate connection points and routing paths, mediating the electrical connection while the vibrator is positioned between the terminals. This intermediary structure simplifies the overall wire configuration by breaking down the direct connection into manageable segments.
2Reliability
If the wire height is increased to prevent interference with the vibrator, then the device height increases, but wire interference with the vibrator is prevented
Solution Approach 1:
The relay substrate routes wires in the horizontal plane rather than increasing vertical height. By providing alternative paths that go around the vibrator laterally, the design achieves interference prevention without sacrificing device compactness in the height dimension.
Solution Approach 2:
The electrical connection path is segmented into multiple sections using the relay substrate. Instead of a single long wire that would need to clear the vibrator vertically, the connection is divided into shorter segments that can be routed through the relay substrate's planar structure, avoiding the need for increased wire height.
3Adaptability or versatility
If the vibrator is disposed between the package terminal and the circuit element terminal, then the wire routing becomes difficult, but the terminal positions are fixed by the application
Solution Approach 1:
The relay substrate serves as a flexible intermediary that can be designed with various routing patterns to accommodate different terminal positions. It provides a platform for creating customized wire paths that adapt to the specific layout requirements while maintaining ease of manufacture through standardized substrate fabrication processes.
Solution Approach 2:
By utilizing the planar dimension of the relay substrate, the design gains flexibility in routing wires without being constrained by vertical clearance issues. This dimensional approach allows for adaptable wire paths that can accommodate fixed terminal positions while simplifying the manufacturing process.
