Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing custom cranial remodeling devices are prone to errors and inaccuracies due to multiple manufacturing steps, and the physical separation of clinics from manufacturing facilities leads to time delays and inefficiencies, while foam liners may not evenly compress and cause spring back issues.
Innovation Solution
Implementing a point-of-service manufacturing process using additive manufacturing devices at clinics, which capture three-dimensional digital data, process it to generate device files, and produce custom cranial remodeling devices on-site, eliminating foam layers and incorporating electronic sensors for real-time adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional multi-step manufacturing process is used, then manufacturing experience and quality control are improved, but manufacturing time and complexity increase
Solution Approach 1:
The patent combines multiple manufacturing steps (3D scanning, digital modeling, and additive manufacturing) into a single integrated workflow that occurs on-site at the clinic. The portable 3D scanner captures head geometry, the data is immediately processed to generate a custom device model, and the additive manufacturer produces the final device all within the same location without physical separation, eliminating shipping delays and reducing total manufacturing time while maintaining precision through digital workflow integration.
Solution Approach 2:
The patent replaces traditional mechanical manufacturing methods (vacuum thermo-forming of foam and plastic layers) with additive manufacturing technology. This substitution eliminates the need for physical molds, manual assembly, and multiple material layers, reducing manufacturing steps from capture→model→foam form→plastic form→assembly to a streamlined digital→additive manufacturing process that produces the final device in one operation.
2Adaptability or versatility
If foam liner is added to extend product life, then adaptability is improved, but manufacturing complexity and potential for inaccuracy increase
Solution Approach 1:
The patent creates a dynamic adaptation system where the additive-manufactured device incorporates adjustable features such as removable inserts, adjustable straps, or modular components that can be modified as the patient grows. This allows the single custom-fitted device to adapt over time without requiring additional foam liners or complex multi-layer construction, maintaining simplicity while providing long-term adjustability.
Solution Approach 2:
The patent extracts the adaptation function from separate foam liner additions and integrates it directly into the additive-manufactured device structure. The device is designed with built-in adjustment mechanisms that are manufactured as part of the single-piece additive process, eliminating the need for separate foam components and reducing overall manufacturing complexity.
3Loss of time
If point of service manufacturing is implemented, then loss of time is reduced, but manufacturing precision and reliability must be maintained
Solution Approach 1:
The patent replaces traditional centralized manufacturing with portable additive manufacturing technology that can be operated at the point of service. This substitution maintains reliability through consistent digital workflow (standardized 3D scanning protocols, automated model generation, and controlled additive manufacturing parameters) while eliminating the need for physical shipping and reducing time delays.
Solution Approach 2:
The patent creates a universal manufacturing system that can be deployed at any clinic location. The portable 3D scanner, computing equipment, and additive manufacturer form an integrated platform that performs all manufacturing functions on-site, ensuring consistent quality regardless of location while eliminating dependency on centralized facilities and physical transportation.

Function Achieved in This Case
This approach reduces manufacturing errors, eliminates time delays, and ensures precise, adjustable devices that accurately fit and monitor patient compliance, enhancing treatment efficacy for cranial deformities.
Implementation Method 1
an additive manufacture device operates to utilize the device file to manufacture the custom cranial remodeling device
Implementation Method 2
vacuum thermo-forming a foam liner onto the life size model, vacuum thermo-forming a hard plastic onto the foam liner
Implementation Method 3
When released from vacuum, there is some spring back of the material. The result of the spring back may result in the foam layer not retaining conformance to the model.
Data Source
AI summary
Custom manufactured headwear for a subject's head is provided. The headwear comprises an inner layer shaped to contact the head of the subject at predetermined areas. The inner layer is deposited by an additive manufacturing device. The headwear further comprises an outer layer deposited by the additive manufacturing device. The inner layer and the outer layer are each formed by the additive manufacture device utilizing a device data file derived from a subject data file. The subject data file is representative of the shape of the head and the device data file determining the shape of the headwear.
