Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Quantity of substance
If the cup capacity is increased, then sufficient solution volume is improved, but stability and ease of operation worsen
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.
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.
3Adaptability or versatility
If multiple manipulations are required for preparation, then adaptability is improved, but ease of operation and reliability deteriorate
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.
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.
