Solution Overview

Problem

Conventional conveyor systems face inefficiencies and reduced lifespan due to high power consumption when changing the direction of object movement from a primary conveyor line to a secondary conveyor line, necessitating a more efficient transfer of rotational motion.

Innovation Solution

A motor driven roller transmission system using a worm gear assembly to transfer rotational motion from a primary rotating member to a secondary rotating member at an angle, allowing the secondary member to rotate at a higher rate, thereby increasing torque output and reducing the required rotational speed of the primary member, thus lowering power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a motor driven roller directly drives a secondary conveyor line at a different speed, then the conveyance direction can be changed, but the power consumption increases and the lifespan decreases

Engineering Contradiction:
Improverotational speed of secondary conveyor lineVSAvoidpower consumption of motor driven roller
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

A transmission assembly serving as an intermediary mechanism transfers rotational motion from the primary motor driven roller to the secondary conveyor line. This intermediary device enables speed transformation while reducing the power requirements on the primary motor, thereby resolving the contradiction between achieving different speeds and maintaining low power consumption.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The transmission assembly changes the rotational speed parameter from the primary roller to the secondary conveyor line. By using gear ratios or belt ratios, the system transforms the rotational speed parameter to match the requirements of the secondary line while keeping the primary motor operating at optimal, lower power consumption speeds.

Inventive Principle:
Principle #35Parameter changes

2Speed

If a motor driven roller directly drives a secondary conveyor line at a different speed, then the conveyance direction can be changed, but the operational lifespan decreases

Engineering Contradiction:
Improverotational speed of secondary conveyor lineVSAvoidlifespan of motor driven roller
Core Design Contradiction:
SpeedVSDuration of action of moving object

Solution Approach 1:

The transmission assembly acts as a protective intermediary that isolates the primary motor driven roller from the full mechanical stress of driving the secondary line at different speeds. This intermediary mechanism reduces wear and stress on the primary roller, thereby extending its operational lifespan while still enabling speed variation in the secondary line.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If the secondary rotating member rotates at a higher rate than the primary rotating member, then the conveyance speed can be increased, but the torque output requirements increase

Engineering Contradiction:
Improverotational speed of secondary rotating memberVSAvoidtorque output required
Core Design Contradiction:
SpeedVSForce

Solution Approach 1:

The transmission assembly serves as a mechanical intermediary that manages the torque requirements. It can provide gear multiplication or belt ratioing that allows the secondary rotating member to operate at higher speeds while the primary motor only needs to provide reduced torque, thus resolving the contradiction between speed increase and torque requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A motor driven roller transmission system for a conveyance assembly includes a transmission assembly connected between a first rotatable member and a second rotatable member, in which the first and second rotatable members are oriented at an angle from one another. The transmission assembly is adapted to efficiently transfer rotational motion of the first rotatable member to the second rotatable member. Rotation of the second rotatable member causes a conveyance surface to move in order to convey an object. The transmission assembly decreases the power required to drive the first rotatable member in order to move the conveyance surface by increasing the torque output of the first rotatable member, while also reducing the rotational speed required of the first rotatable member to drive the conveyance surface at a desired speed, thus extending the operational life of the first rotatable member.
