Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional woodworking processing machines require slow and energy-consuming adjustments for cutter seat height changes, especially when processing wood of varying thicknesses, making the process inconvenient and time-consuming.
Innovation Solution
A working height adjustment device featuring a slide seat with an adjustment seat containing an elastic member, a movable member with a toothed engaging hole, and a push knob, allowing the micro adjustment rod to be rapidly rotated or pulled to quickly adjust the cutter seat height through a control rod and link rod mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the micro adjustment rod is used to adjust the cutter seat height, then the adjustment precision is improved, but the adjustment speed deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the adjustment mechanism switchable between two states: fine adjustment mode (using the threaded micro adjustment rod for precision) and rapid adjustment mode (using the control rod pulled up by the elastic member for speed). The system dynamically adapts its adjustment characteristics based on the operational needs, allowing operators to choose between precision and speed as required.
Solution Approach 2:
The adjustment function is segmented into two distinct mechanisms: the micro adjustment rod with threaded section for fine adjustments, and the control rod with link rod for rapid adjustments. By dividing the adjustment function into separate mechanisms with specialized functions, the system achieves both high precision and high speed capabilities without compromising either aspect.
2Manufacturing precision
If the micro adjustment rod is turned to adjust the slide seat position, then the adjustment accuracy is improved, but the time consumption increases
Solution Approach 1:
The system dynamically switches between fine adjustment mode (threaded rod for accuracy) and rapid adjustment mode (elastic member pulling control rod for speed). This dynamic adaptability allows the system to minimize time consumption while maintaining adjustment accuracy when needed, resolving the trade-off between precision and time efficiency.
Solution Approach 2:
The elastic member is pre-loaded to store potential energy, enabling rapid adjustment without manual turning. The preliminary storage of energy in the elastic member allows for quick displacement of the control rod and link rod, significantly reducing adjustment time while maintaining positioning accuracy through the toothed portion engagement.
3Measurement precision
If the rotatable handle is turned to move the cutter seat, then the height adjustment precision is improved, but the energy consumption increases
Solution Approach 1:
The system dynamically selects between manual fine adjustment (low energy, high precision) and elastic-driven rapid adjustment (higher energy release, faster speed). The elastic member stores and releases energy to perform rapid adjustments, reducing the manual energy input required from the operator while maintaining adjustment precision through the engagement mechanism.
Solution Approach 2:
The patent substitutes the pure manual mechanical turning system with a hybrid system that incorporates elastic potential energy. The elastic member replaces part of the manual mechanical input, using stored elastic energy to drive the rapid adjustment, thereby reducing the energy consumption from the operator while maintaining adjustment capability.
