Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belts used in conveyor belt scales face challenges in maintaining optimal tension and smooth operation at high speeds, which affects the accuracy of weight determination.
Innovation Solution
A conveyor belt with a belt guide device featuring rolling bearings, where the inner rings are mounted on axles that are either shared or separate and parallel, providing precise alignment and support without the need for manual alignment or balancing, and the outer rings contact the conveyor belt to ensure smooth running and reduce wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conveyor roller is used to tension the conveyor belt, then the conveyor belt can be maintained in tension, but the alignment of the conveyor roller must be precise to ensure smooth running and accurate weight determination
Solution Approach 1:
The patent replaces the traditional conveyor roller with a deflector plate that utilizes the gravity force of the conveyor belt itself to maintain tension and guide the belt. This substitution eliminates the need for mechanical alignment of rollers while maintaining reliable belt operation and accurate weight determination.
2Device complexity
If a deflector plate is used to guide the conveyor belt, then the structure is simplified, but the conveyor belt runs unevenly and wears out more quickly
Solution Approach 1:
The patent applies local quality by creating a V-shaped groove on the deflector plate that concentrates the conveyor belt's contact to a specific localized area. This localized guidance structure ensures the belt runs smoothly and evenly across the deflector plate, preventing uneven running and reducing wear while maintaining structural simplicity.
3Reliability
If manual alignment and balancing of the belt guide device is performed, then the conveyor belt can run smoothly, but the assembly process becomes time-consuming and complex
Solution Approach 1:
The patent implements self-service by designing the deflector plate with an integrated V-shaped groove that automatically guides and centers the conveyor belt during operation. The belt's own weight and movement cause it to naturally settle into the V-groove alignment, eliminating the need for manual alignment and balancing operations during assembly.
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 solution enables the conveyor belt to run smoothly and accurately at high speeds, enhancing the precision of weight determination by eliminating the need for alignment and balancing steps and reducing wear on the belt guide device.
Implementation Method 1
The outer rings of the rolling bearings are in direct contact with the conveyor belt... the conveyor belt runs more smoothly than with a belt guide device that tensions the conveyor belt with a conveyor roller

AI summary
The invention relates to a conveyor belt scale with a conveyor belt and a conveyor belt itself. The conveyor belt for transporting unit loads comprises a belt body with a top surface, a bottom surface, and a length extending in the transport direction of the unit load, and a transport belt that rotates around the belt body during operation. A belt guide device is provided, comprising at least two rolling bearings. The inner rings of the rolling bearings are each mounted on an axle, the axles being arranged parallel to each other and fixed in position with respect to the belt body.
