Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing zone control systems in conveyor systems are limited in load capacity and introduce inefficiencies, as they lack effective mechanisms to selectively activate and deactivate zones for efficient goods transportation.
Innovation Solution
A zone control system comprising a roller with a drive and driven portion separated by a spring, actuated by an air bladder or actuator, allowing for controlled engagement and disengagement to manage the operational state of the roller, enhancing load capacity and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing control methods are used to selectively activate and deactivate zones, then zones can be controlled to transport goods, but load capacity is limited and inefficiencies are introduced
Solution Approach 1:
The patent employs a pneumatic actuator system with air bladders to control the engagement and disengagement of drive and driven portions in conveyor rollers. Compressed air inflates the bladders to engage the drive portion with the driven portion, enabling zone activation, while deflation disengages them for accumulation. This pneumatic mechanism provides reliable, scalable control that handles varying load capacities without introducing excessive mechanical complexity.
2Productivity
If zones are selectively activated and deactivated to allow goods accumulation, then efficiency is improved, but existing mechanisms introduce new inefficiencies
Solution Approach 1:
The pneumatic actuator system is integrated directly into the roller assembly, allowing each zone to independently control its own engagement state without requiring external mechanical linkages or complex control systems. The air bladder mechanism self-regulates the drive engagement based on pneumatic pressure, eliminating the need for additional actuators, linkages, or control components that would consume energy and reduce overall system efficiency.
3Force
If rollers are used to control zone engagement, then goods can be transported, but load capacity is limited
Solution Approach 1:
The pneumatic actuator with air bladders provides scalable force generation that can handle varying load capacities. By adjusting air pressure, the system can engage drive portions with sufficient force to move heavy goods while maintaining easy control through simple pneumatic valve operation. This eliminates the limitations of mechanical leverage systems and provides proportional force control that scales with operational requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables efficient activation and deactivation of zones, improving load handling capacity and reducing inefficiencies by using a spring and actuator mechanism to manage the engagement of drive and driven portions, thereby optimizing conveyor system operations.
Implementation Method 1
a spring disposed between the drive portion and the driven portion, wherein the spring is configured to transition between an extended state, such that the drive portion and the driven portion are separated by a gap and refrain from operably engaging, and a compressed state, such that the drive portion and the driven portion are operably engaged
Implementation Method 2
a bladder configured to transition between a filled state and an empty state, wherein the bladder is operably engaged with the actuator, wherein, when the bladder is in the filled state, the spring is compressed and the drive portion and driven portion are operably engaged, and, wherein, when the bladder is in the empty state, the spring is extended and the drive portion and driven portion refrain from operably engaging
