Solution Overview

Problem

Existing kits for preparing pharmaceutical or medicinal products for intravenous self-injection are limited by small solution volumes, instability, and complex user manipulation, leading to increased risks of contamination, incorrect handling, and burns during heating.

Innovation Solution

A single-use, sterile kit with a cup and handle assembly, featuring a concave dish with stabilizing tabs and integral thermal insulation, designed for larger volumes and improved stability, with a handle that includes non-slip grooves and a stabilization tab to protect against burns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a separate heat-insulating tip is added to the grip sleeve, then user protection from burns is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improveburn riskVSAvoidassembly complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The thermal insulation function is merged with the handle by integrating an insulating grip portion directly into the handle structure. This eliminates the need for a separate heat-insulating tip that must be assembled, while still providing burn protection to the user's fingers during heating operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The thermal insulation is built into the handle during manufacturing, so the protective function is already in place before the user receives the device. This eliminates the need for users to perform the meticulous task of attaching a separate insulating tip, which they might do incorrectly or forget entirely.

Inventive Principle:
Principle #10Preliminary action

2Quantity of substance

If the cup capacity is increased, then sufficient solution volume is improved, but stability and ease of operation worsen

Engineering Contradiction:
Improvesolution volumeVSAvoiddevice stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

Stability is achieved by extending the device horizontally with a long handle rather than increasing the vertical height or base width of the cup. The handle provides a counterbalancing dimension that lowers the center of gravity and prevents tipping, allowing the cup to maintain a larger capacity without compromising stability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The device features an asymmetric design with a long handle extending from one side of the cup. This asymmetric configuration creates a stable center of gravity that prevents the cup from tipping over, even when the cup itself has a relatively large capacity for a single-use device.

Inventive Principle:
Principle #4Asymmetry

3Adaptability or versatility

If multiple manipulations are required for preparation, then adaptability is improved, but ease of operation and reliability deteriorate

Engineering Contradiction:
Improvepreparation flexibilityVSAvoiduser operation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The device is provided in a ready-to-use state with all necessary components pre-assembled and the cup sterile-packaged. Users simply need to open the packaging and begin preparation, eliminating multiple manipulation steps that require dexterity and attention to detail.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The integrated handle serves multiple functions simultaneously: it provides structural support, thermal insulation during heating, and a gripping surface for manipulation. This multi-functionality reduces the number of separate components users must handle while maintaining operational flexibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)
