Sequential Allergen Introduction Kit for Infant Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for early introduction of food allergens to infants are difficult to implement and often start too late, leading to increased food allergy incidence, as they require complex regimens and universal screening, which are not feasible for all infants, and many children develop allergies before the recommended exposure age.
Innovation Solution
A multiple allergen early introduction system in the form of a kit containing individually packaged protein powders that can be easily mixed with breast milk or formula, with a stepwise daily dosing regimen to introduce major food allergens sequentially and gradually, allowing for early exposure even before six months of age, simplifying the process and reducing the need for extensive screening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex regimens and universal screening are implemented for early allergen introduction, then food allergy incidence can be reduced, but implementation difficulty and complexity increase significantly
Solution Approach 1:
The patent segments the allergen introduction process into distinct stages (exposure phase with increasing doses, then maintenance phase) and separates different allergens into individually packaged proteins. This allows the complex prevention regimen to be broken down into manageable, sequential steps that are easier to implement while maintaining effectiveness.
Solution Approach 2:
The patent employs parameter changes by systematically varying the dose of allergen proteins during the exposure phase (increasing from lower to higher doses over time) and then transitioning to maintenance doses. This structured parameter variation enables effective tolerance development while providing a clear, followable protocol that reduces implementation complexity.
2Reliability
If early allergen introduction is delayed until recommended ages, then safety concerns are reduced, but the immunological window for tolerance development is missed, leading to increased allergy incidence
Solution Approach 1:
The patent applies preliminary action by initiating allergen exposure during the critical immunological window in infancy, before the immune system fully develops Th2 dominance. This early timing captures the developmental period when the immune system is most amenable to tolerance induction, preventing the loss of this critical window while maintaining safety through controlled dosing.
3Reliability
If allergen proteins are introduced in non-standardized forms, then flexibility in administration is maintained, but dosing precision and tolerance induction effectiveness decrease
Solution Approach 1:
The patent implements self-service by providing pre-measured, individually packaged allergen proteins that caregivers can directly mix with breast milk or formula without requiring preparation, measurement, or complex handling. Each package contains the precise dose needed for that day, eliminating dosing errors and simplifying administration while ensuring standardized, effective dosing.
4Object-affected harmful factors
If extensive screening is required before allergen introduction, then safety is improved, but feasibility for universal implementation decreases
Solution Approach 1:
The patent segments the risk management approach by introducing allergens one protein at a time in a controlled sequence rather than requiring comprehensive screening for all potential allergens beforehand. This segmented approach allows safety monitoring at each step while making the program feasible for universal implementation without extensive preliminary screening.

AI summary
A method and kit for the sequential early introduction to an infant of at least nine allergens to decrease the infant's risk for developing allergies. The method and kit includes an initial lower exposure dose of a first allergen to be taken for a day or two, followed by a higher maintenance dose of the first allergen to be taken for a day or more. Additional allergens are added, each first at an initial lower dose for a day or more followed by a higher maintenance dose for a day or more. This patent continues until all nine allergens are being given to an infant at their maintenance doses. The allergens can be provided in powdered protein form in premeasured pouches for addition to baby formula/mother's milk. Alternatively, the allergens can be included in baby formula, or in other foods such as snack bars, cookies, or gels.
