Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drug injection systems for treatments like botulinum toxin require frequent medical professional visits, are costly, cumbersome, and lack scalability due to individual customization, and involve manual reconstitution risks.
Innovation Solution
A method using standardized personal drug injection systems selected based on anthropometric characteristics, allowing self-administration and integrating automation to simplify drug delivery, reducing reliance on clinicians and minimizing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual customisation of masks is implemented to fit specific users, then injection precision and patient-specific accuracy are improved, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The invention divides the population into discrete size groups (small, medium, large, extra-large) based on anthropometric characteristics. Each size group has a corresponding standardized mask design with pre-defined injection locations. This segmentation allows the system to achieve patient-specific accuracy without requiring fully customised masks for each individual, thereby reducing manufacturing complexity while maintaining injection precision.
Solution Approach 2:
The invention changes the parameter of mask design from fully customised to standardized size variants. By defining discrete size categories and corresponding injection location patterns, the system transforms the continuous customization parameter into discrete standardized options. This parameter change enables mass production of standardized masks while still providing appropriate fit and accuracy for different patient populations.
2Manufacturing precision
If bespoke mask production is used for each patient, then injection pattern precision is improved, but production time and cost effectiveness deteriorate
Solution Approach 1:
The invention performs preliminary action by pre-defining injection location patterns for each standardized mask size during the manufacturing process. The injection locations are predetermined and built into the mask design for each size category, eliminating the need for time-consuming customisation and measurement procedures at the point of patient treatment. This preliminary preparation maintains injection pattern accuracy while dramatically improving production efficiency and cost-effectiveness.
3Reliability
If medical professionals administer injections manually, then injection control and safety are improved, but patient convenience and accessibility worsen
Solution Approach 1:
The invention enables self-service by providing patients with standardized masks that have pre-defined injection locations and integrated injection devices. Patients can self-administer injections at home without requiring visits to medical professionals, thereby improving convenience and accessibility. The standardized design ensures adequate safety and control by providing clear guidance on injection locations and using automated or semi-automated injection mechanisms that reduce the risk of error.
4Reliability
If frequent treatment visits are required, then treatment efficacy is maintained, but time consumption and cost burden increase
Solution Approach 1:
The invention enables patients to perform treatments at home without requiring frequent visits to medical facilities. By providing standardized masks with pre-defined injection locations and integrated injection devices, the system allows patients to self-administer treatments on schedule, maintaining treatment effectiveness while eliminating travel time and waiting time associated with clinic visits.

AI summary
A method of providing a personal drug injection system is disclosed. The method comprises determining at least one anthropometric characteristic from a person, and providing a plurality of types of personal drug injection systems. Each personal drug injection system of a personal drug injection system type is configured so as to fit with a part of the person's body that is intended to receive an injectable drug, and includes a drug injection location set that includes at least one defined drug injection location corresponding to a location of a drug injection site on the part of the person's body when the personal drug injection system is disposed on the part of the person's body. Each personal drug injection system type is associated with a defined range of anthropometric characteristics that is different to the defined range of anthropometric characteristics associated with the other personal drug injection system types, and each personal drug injection system type has an associated drug injection location set that is different to the drug injection location set of the other personal drug injection system types. The method also involves using the determined anthropometric characteristic and the defined ranges of anthropometric characteristics to select one of the personal drug injection system types from the plurality of personal drug injection system types already manufactured, and providing the person with the selected personal drug injection system type.
