Innovation Solution

An automated condiment dispenser system that includes a cabinet with shelves and a conveyor system, actuator, and robotic arm with vacuum cups, controlled by a controller to accurately dispense condiment containers based on customer requests, improving efficiency and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual condiment dispensing is used, then device complexity is low, but productivity and accuracy deteriorate due to time-consuming operations and frequent errors

Engineering Contradiction:
Improvecondiment dispensing speedVSAvoiddispensing system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables self-service automation where the condiment dispenser autonomously receives orders from the point-of-sale system, identifies required condiments, activates appropriate conveyors and actuators, and dispenses containers without human intervention. The controller coordinates all components automatically, transforming a manual task into an autonomous self-serving system that improves productivity while managing complexity through integrated control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations with an automated control system that uses electrical signals to activate conveyors, actuators, and robotic components. The controller substitutes human decision-making and physical manipulation with electronic control logic, enabling faster and more accurate condiment dispensing while reducing the complexity of manual coordination.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If manual condiment placement is used, then equipment cost is low, but manufacturing precision and reliability worsen due to incorrect or missing condiments

Engineering Contradiction:
Improvecondiment placement accuracyVSAvoidautomated dispensing system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system incorporates feedback mechanisms where sensors detect the presence and position of condiment containers on conveyors and staging surfaces. The controller receives this feedback information and adjusts actuator activation timing and conveyor operation to ensure accurate placement. This closed-loop control enables precise condiment dispensing while managing system complexity through intelligent coordination of multiple components.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The dispensing system is segmented into independent functional modules: storage shelves, conveyors for each condiment type, staging surfaces, actuators, and sensors. Each module operates semi-independently under controller coordination, allowing the system to achieve high precision through modular design while managing overall complexity by dividing functions into manageable segments.

Inventive Principle:
Principle #1Segmentation

3Productivity

If automated dispensing system is implemented, then productivity improves, but use of energy worsens due to motors, actuators, and control systems

Engineering Contradiction:
Improveorder fulfillment speedVSAvoidenergy consumption of dispensing system
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The automated dispensing system operates periodically rather than continuously - conveyors and actuators are activated only when condiments are needed based on customer orders. The controller receives order information and triggers dispensing operations at specific intervals, enabling the system to maintain high productivity when active while consuming minimal energy during idle periods between orders.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system maintains continuous readiness for dispensing operations with components positioned and prepared in advance. Conveyors keep condiments in motion or ready positions, and actuators remain poised for activation, ensuring that when an order is received, the useful action of dispensing can proceed continuously without interruption or delays, maximizing productivity while minimizing energy waste from repeated start-stop cycles.

Inventive Principle:
Principle #20Continuity of useful action
