Ultraminiature Tuning Fork Quartz Structure With Silver Glue Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ultraminiature tuning fork quartz crystal resonators face a challenge where opening holes at the connecting ends of the electrical connecting arms weakens the strength of these arms, leading to a reduced service life of the chip.
Innovation Solution
The design incorporates a symmetrical structure with connecting arms that extend outward from a fixing block, featuring at least one groove group on the outer walls for filling conductive silver glue, which enhances the connection strength by guiding the glue flow and wrapping around the arms, thereby avoiding the need for holes that weaken the arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If holes are opened at the connecting end of the electrical connecting arms to fill conductive silver glue, then the tightness of connection between the connecting arms and resonator base is improved, but the strength of the connecting arms is weakened
Solution Approach 1:
The patent transitions from a through-hole structure (penetrating the connecting arm) to a surface groove structure (on the outer wall). This dimensional change allows the conductive silver glue to be contained within grooves that do not compromise the structural integrity of the connecting arms, thereby maintaining both connection tightness and arm strength.
Solution Approach 2:
The patent introduces grooves at specific locations on the outer wall of the connecting arms where conductive silver glue needs to be applied. This localized modification provides targeted adhesion enhancement without weakening the entire connecting arm structure, resolving the contradiction between connection tightness and overall strength.
2Duration of action of moving object
If the tuning fork crystal chip is miniaturized to reduce power consumption and improve portability, then the service life in power-saving mode is extended, but the connection strength between the chip and base is reduced
Solution Approach 1:
By moving the conductive silver glue application from through-holes to surface grooves on the outer wall, the patent enables better glue distribution and adhesion in miniaturized structures. This allows the resonator to maintain strong connections even as the overall size is reduced for portability and extended service life.
Solution Approach 2:
The groove structure creates a controlled porous-like surface that enhances the adhesion of conductive silver glue to the connecting arms. This increased surface area for bonding compensates for the reduced size of miniaturized components, maintaining connection strength despite smaller dimensions.
