Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a device is designed to provide precise control over topical compound dispensation, then measurement precision and manufacturing precision are improved, but device complexity increases

Engineering Contradiction:

Improveprecision of topical compound applicationVSAvoidcomplexity of delivery device

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The device employs a nested structure where a tip portion is inserted into and connected with a syringe. The cap surrounds the syringe tip and contains the membrane assembly, creating a compact nested configuration that provides precise dispensation control without significantly increasing overall device complexity

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

A selectively permeable membrane is introduced as an intermediary component between the syringe and the external environment. This membrane controls the release of topical compounds through controlled pores, enabling precise dispensation while maintaining a relatively simple device structure

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a device is designed to be compatible with existing syringe types, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvecompatibility with syringe typesVSAvoidcomplexity of connection mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is designed with universal compatibility in mind, allowing the same tip portion and cap assembly to be attached to various syringe types (insulin syringes, hypodermic syringes, etc.). The connection mechanism accommodates different syringe configurations while maintaining consistent functionality across multiple applications

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device is segmented into separate components: a tip portion that attaches to the syringe tip, and a cap that surrounds the tip portion. This segmentation allows the device to be adapted to different syringe types by maintaining the modular connection interface while keeping the functional elements separate and interchangeable

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If manual control of syringe plunger is used, then ease of operation is improved, but loss of substance increases due to waste and overmedication

Engineering Contradiction:

Improveease of syringe operationVSAvoidwaste of topical compound

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The device incorporates feedback mechanisms that monitor and control the dispensation of topical compounds. The selectively permeable membrane with controlled pores provides feedback on compound release rates, preventing overmedication and waste while maintaining ease of operation through automatic regulation

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The device enables self-service control where the membrane assembly automatically regulates the release of topical compounds based on the syringe pressure and flow characteristics. This self-regulating mechanism eliminates the need for precise manual control while preventing substance loss through waste and overmedication

Inventive Principle:

Principle #25Self-service

AI summary

Disclosed herein are devices, systems, and methods for applying and/or delivering topical compounds (e.g., topical medications) to the surface of mammalian tissue (e.g., skin, mucous membranes, and/or other tissue surfaces). Specifically, disclosed embodiments include a device that is configured to connect to one or more types of known syringes, and, in particular, to one or more types of known syringe tips. At least one embodiment of the device comprises a cap and a membrane, where the cap includes an open connector end for engaging and/or attaching to a syringe via a syringe tip, a delivery end opposite to the connector end, and a cap body disposed between, and connecting, the connector end and the delivery end. The delivery end can further be connected to the membrane by, for instance, inserting one end of the membrane into the delivery end.
