Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a plaster cast is used to immobilize and stabilize the injured limb, then the anatomical structure is stabilized, but the procedure becomes time-consuming and requires multiple healthcare providers

Engineering Contradiction:
Improvestabilization of anatomical structureVSAvoidtime for applying cast
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The cast is divided into two separate halves (first cast part and second cast part) that can be independently prepared and then joined together. This segmentation allows parallel preparation of components, reducing the overall time required while maintaining the stability function of the complete cast structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first and second cast parts are pre-formed with complementary joining features (protrusions and recesses) before application. This preliminary preparation of components enables rapid assembly on the patient, reducing the time required during the actual casting procedure while ensuring proper alignment and stability.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a plaster cast is applied to an anatomical structure, then immobilization is achieved, but the cast may loosen due to reduction in swelling

Engineering Contradiction:
ImproveimmobilizationVSAvoidfit of cast
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The cast design incorporates adjustable fastening elements that allow the cast to be dynamically adjusted after application. As swelling reduces, the fastening mechanism can be tightened to maintain proper fit and immobilization, transforming the cast from a static to a dynamically adaptable structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cast includes adjustable parameters such as fastening tension and positioning that can be modified after application. This allows the cast to adapt to changing anatomical dimensions due to swelling reduction, maintaining optimal immobilization throughout the healing process.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If conventional plaster casting is used, then immobilization is achieved, but multiple attempts may be required leading to increased healthcare resource utilization

Engineering Contradiction:
ImproveimmobilizationVSAvoidtreatment efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The segmented cast design with pre-formed joining features enables proper alignment and secure assembly on the first attempt. The modular structure with complementary protrusions and recesses provides built-in guidance for correct positioning, eliminating the need for multiple attempts and improving treatment efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cast design incorporates self-aligning features where the protrusions and recesses automatically guide proper positioning during assembly. This self-service mechanism reduces dependency on operator skill and experience, enabling consistent successful application and reducing the need for multiple attempts.

Inventive Principle:
Principle #25Self-service

4Reliability

If a rigid cast structure is used for stabilization, then immobilization is effective, but flexibility and adjustability are reduced

Engineering Contradiction:
ImprovestabilizationVSAvoidadjustability of brace
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The cast incorporates dynamic fastening elements that allow adjustment of the cast's tightness and positioning after application. This dynamic feature provides flexibility and adaptability while maintaining the rigid structural support needed for effective stabilization of the anatomical structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The segmented design with separate first and second cast parts allows independent adjustment of each portion. This segmentation provides flexibility in positioning and fitting while maintaining the overall rigid structure necessary for stabilization, enabling customization to patient-specific needs.

Inventive Principle:
Principle #1Segmentation

AI summary

A brace and a method for manufacturing a brace is disclosed. The brace is for management of an anatomical structure comprising a primary anatomical structure, a secondary anatomical structure, and a joint and/or an injury between the primary anatomical structure and the secondary anatomical structure. The brace comprises a first brace part extending from a first primary brace part end to a first secondary brace part end and being adapted to be positioned to cover a first part of the anatomical structure extending over the joint and/or injury such that the first primary brace part end is located on the primary anatomical structure and the first secondary brace part end is located on the secondary anatomical structure. The first brace part comprises a first rigid outer shell and one or more first lattice structures attached to a first inner side of the first rigid outer shell.
