Movement Adjustment Apparatus for Independent Motion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machinery for packaging and processing requires complex motor drive systems to manage specific motion rules for each element, leading to high production costs and limited reconfiguration capabilities, as well as reduced productivity due to the need for continuous operation of all elements following a common motion rule.
Innovation Solution
A movement assembly comprising a supporting frame with a driving element and a movement adjustment apparatus, including a contoured guide, levers, and linkages, allows for independent movement of elements according to predefined rules of motion without requiring individual controlled motor drive units, enabling variable acceleration and deceleration while maintaining constant speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If controlled motor drive units are used for each movable element, then each element can move independently according to specific rules of motion, but production costs increase considerably and complex control systems are required
Solution Approach 1:
The system segments the motion control function by separating the driving element (common motor) from the movable elements (packages), allowing independent motion control through mechanical linkages rather than individual motor drives for each element
Solution Approach 2:
The patent introduces an intermediary mechanism (the linkage system with guides and levers) between the single driving element and multiple movable elements, enabling independent motion control without requiring individual motor drives for each element
2Manufacturing precision
If controlled motor drive units are used for each movable element, then specific rules of motion can be complied with perfectly, but production costs increase due to purchase costs of individual units
Solution Approach 1:
The single driving element serves multiple functions by controlling multiple movable elements through the shared linkage system, eliminating the need for separate motor drives for each element and reducing overall production costs
3Ease of manufacture
If all elements follow a common rule of motion on a single conveyance element, then production costs are reduced, but productivity decreases due to continuous operation requirement and stopped elements affecting all
Solution Approach 1:
The system segments the motion control so that while elements share a common driving element, their individual motion is independently controlled through linkages, allowing selective stopping and acceleration of specific elements without affecting others, thus maintaining high productivity
4Adaptability or versatility
If individually controlled motor drive units are used, then reconfiguration possibility is available, but in many cases the reconfiguration capability is not utilized fully and validly
Solution Approach 1:
The linkage system provides dynamic reconfiguration capability through movable joints and adjustable linkages that can be modified during operation, allowing the system to adapt to different motion requirements without requiring complete system replacement, thereby fully utilizing reconfiguration potential
