Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispersion tables used for conveying adhesive articles, such as raw chicken, face issues like high cost, poor hygiene, adhesion, and limited conveyance force, especially when inclined, leading to rolling and layout constraints, particularly on conical shapes.
Innovation Solution
A combination weighing apparatus with a dispersion table featuring inclined faces on its surface, which reduces adhesion and enhances conveyance by applying vibration and rotation, using conveyors and hoppers for weight calculation, and a controller for combination weighing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a motor-driven rotation method is used to convey adhesive articles on a dispersion table, then conveyance capability is improved, but cost increases and hygiene deteriorates
Solution Approach 1:
The patent replaces the motor-driven rotation system with a vibration-based conveyance system. The dispersion table uses vibration excitation to move adhesive articles without requiring complex motor mechanisms, thereby reducing cost while maintaining conveyance capability and improving hygiene through simpler, easier-to-clean surfaces
2Ease of manufacture
If vibration is used to convey adhesive articles on a dispersion table, then cost is reduced, but adhesion increases causing conveyance failure
Solution Approach 1:
The patent applies local quality by creating uneven surface structures (protrusions and recesses) on specific regions of the dispersion table. These localized surface variations reduce adhesion between adhesive articles and the table surface, enabling reliable conveyance through vibration without requiring increased overall vibration intensity that would cause rolling
3Force
If the inclination angle of the dispersion table is increased to prevent adhesion, then conveyance force transmission is improved, but articles roll down causing dispersiveness deterioration
Solution Approach 1:
The patent uses localized surface unevenness (protrusions and recesses) rather than increasing overall inclination angle. The protrusions reduce adhesion locally, allowing conveyance force to be transmitted effectively through vibration while maintaining table inclination at angles that prevent excessive rolling and preserve article dispersiveness
4Speed
If the inclination angle of the dispersion table is increased to improve conveyance, then conveyance capability is improved, but apparatus height increases limiting layout
Solution Approach 1:
The patent uses mechanical vibration as the primary conveyance mechanism on a horizontally or mildly inclined dispersion table. This approach achieves effective article conveyance without requiring steep inclination angles, thereby maintaining compact apparatus height and providing layout flexibility while preserving conveyance capability
5Force
If serrated unevenness or groove is provided to counter adhesion, then conveyance force transmission is improved, but application to conical dispersion tables becomes difficult
Solution Approach 1:
The patent adapts the unevenness concept to conical dispersion tables by using protrusions and recesses that follow the curved conical surface geometry. This maintains the adhesion-reducing effect and conveyance force transmission benefits of serrated structures while being compatible with the conical shape, enabling easy manufacturing through standard forming processes
