Percussive Adjusting Instrument With Y-Axis Pivot Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional percussive adjusting instruments are limited to movements only about the X and Z axes, failing to account for the Y-axis, leading to imprecise adjustments in chiropractic treatments.
Innovation Solution
A percussive adjusting instrument designed to move along the X, Y, and Z axes, incorporating a Y-axis pivot assembly with a central gear and pivot gear mechanism, allowing precise adjustments by pivoting about the Y-axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional percussive adjusting instruments are used with limited movement only about X and Z axes, then the device structure remains simple, but the adjustment precision is insufficient
Solution Approach 1:
The patent introduces Y-axis rotational capability to the existing X-Z axis movement system, transforming a two-dimensional adjustment plane into a three-dimensional adjustment space. The Y-axis pivot assembly with central gear and pivot gear mechanism enables the instrument head to rotate about the Y-axis in addition to moving along the X and Z axes, providing comprehensive three-axis movement capability that allows precise adjustments from multiple angles and improves measurement precision
2Adaptability or versatility
If the instrument head is made movable about all three axes (X, Y, Z), then adjustment versatility is improved, but the mechanism complexity increases
Solution Approach 1:
The patent divides the movement control into three independent segments: X-axis linear movement, Y-axis rotational movement, and Z-axis linear movement. Each axis has its own control mechanism, allowing independent adjustment of each degree of freedom. This segmentation enables versatile three-dimensional positioning while keeping each individual mechanism relatively simple and manageable
Solution Approach 2:
The instrument head is designed with dynamic movement capabilities along all three axes, transitioning from a fixed or limited two-axis system to a fully dynamic three-axis system. The Y-axis pivot assembly enables dynamic rotation about the Y-axis, allowing the instrument to adapt its orientation and positioning in three-dimensional space to accommodate various adjustment requirements
3Measurement precision
If a Y-axis pivot assembly with central gear and pivot gear is added, then measurement accuracy along Y-axis is improved, but the device complexity worsens
Solution Approach 1:
The patent replaces manual positioning methods with a gear-based mechanical transmission system for Y-axis rotation. The central gear connected to the Y-axis pivot control knob and the pivot gear mechanism provide precise mechanical control over the Y-axis rotational movement, enabling accurate measurement and adjustment along the Y-axis through controlled gear engagement and disengagement

AI summary
A percussive adjusting instrument is provided which includes a percussive instrument head and a traversing arm that couples to the percussive instrument head. The percussive instrument head is movable with respect to the traversing arm. A vertical arm supports the traversing arm. The vertical arm also pivots the traversing arm and the percussive instrument head about an axis. A pivot assembly allows movement of the vertical arm and the percussive instrument head.
