Solution Overview

Problem

Existing impregnation devices for small wearable items, such as shoes, waste substantial amounts of impregnating agent and extend drying time due to excessive use, leading to inefficiency and prolonged treatment cycles.

Innovation Solution

A treatment apparatus with a rotatable turntable and nozzles inside a closed chamber, using markers and scanners to control nozzle activation based on item position, allowing precise application of impregnating agent and reducing overlap, combined with a plateau for multi-tier treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a substantial quantity of impregnating agent is used to achieve sufficient treatment, then thorough impregnation is achieved, but impregnating agent is wasted and drying time is extended

Engineering Contradiction:
Improvethorough impregnationVSAvoidimpregnating agent waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The turntable rotates during treatment to dynamically change the position of items relative to stationary nozzles, enabling uniform distribution of impregnating agent across all surfaces without requiring excessive amounts of agent. This dynamic positioning ensures thorough coverage while minimizing waste.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The scanner detects markers on the turntable to provide feedback on item position, allowing the control unit to precisely control nozzle activation timing. This feedback mechanism ensures impregnating agent is applied only when needed and in the correct amount, preventing both waste and insufficient treatment.

Inventive Principle:
Principle #23Feedback

2Reliability

If a substantial quantity of impregnating agent is used to achieve sufficient treatment, then thorough impregnation is achieved, but drying time is extended

Engineering Contradiction:
Improvethorough impregnationVSAvoiddrying time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The rotating turntable enables uniform distribution of impregnating agent in a controlled manner, preventing pooling or excessive application in any one area. This dynamic application method achieves thorough treatment with minimal agent, thereby reducing drying time without compromising impregnation quality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The treatment process uses periodic activation of nozzles synchronized with turntable rotation, applying impregnating agent in controlled intervals rather than continuously. This periodic action ensures adequate coverage while allowing evaporation between applications, reducing overall drying time.

Inventive Principle:
Principle #19Periodic action

3Area of stationary object

If the nozzle sprays impregnating agent continuously, then coverage is comprehensive, but agent waste increases and treatment precision decreases

Engineering Contradiction:
Improvecoverage areaVSAvoidapplication precision
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The system transforms continuous spraying into controlled intermittent spraying by synchronizing nozzle activation with turntable position feedback. This dynamic control maintains comprehensive coverage by targeting all areas over time while achieving high precision in each application instance, eliminating both waste and imprecision.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The marker detection system provides real-time feedback on turntable position, enabling the control unit to activate nozzles at precise moments when items are in the optimal position. This feedback-controlled timing ensures agent is applied only where needed, achieving both comprehensive coverage and high application precision without waste.

Inventive Principle:
Principle #23Feedback
