Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Healthcare simulation models require removable and replaceable covers that maintain realistic haptics, but current designs are difficult to fit and often require visible fasteners, leading to inefficiencies and increased manufacturing costs.
Innovation Solution
A cover design with strategically placed openings and fasteners that allow for secure alignment and attachment without visible fasteners, enabling easy fitting and replacement, using features like recesses and magnets to enhance usability and realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover is made from tensile materials to maintain tight fit and realistic haptics, then the haptic realism is improved, but the replacement process becomes time-consuming and difficult
Solution Approach 1:
The cover is divided into two separate layers: an inner layer that fits tightly to the core for haptic realism, and an outer layer that can be independently removed and replaced. This segmentation allows the outer layer to be changed without affecting the inner layer's secure fit, resolving the contradiction between maintaining tight fit and enabling easy replacement.
2Ease of operation
If a longitudinal slit with visible fixing mechanism is used to improve ease of fitting, then the ease of operation is improved, but the haptic realism and manufacturing cost deteriorate
Solution Approach 1:
The fixing mechanism is extracted and relocated to the inner layer, which remains hidden beneath the outer layer. The outer layer can be fitted easily over the core without any visible fasteners or slits, maintaining haptic realism while still allowing for easy application and removal.
3Ease of operation
If the outer layer is applied using the glove-to-hand method, then the ease of operation is improved, but the vein positioning accuracy deteriorates due to vein movement
Solution Approach 1:
By separating the cover into inner and outer layers that can be applied independently, the inner layer can be precisely fitted with veins correctly positioned first, then the outer layer is applied over it. This prevents vein displacement while maintaining ease of application.
4Manufacturing precision
If multiple repetitions of removal and re-application are required to correct vein positioning, then the manufacturing precision can be improved, but the productivity deteriorates
Solution Approach 1:
The separable inner and outer layer design allows precise vein positioning to be achieved in a single application of the inner layer, while the outer layer can be independently replaced without affecting vein position. This eliminates the need for repeated removal and re-application, improving both precision and productivity.
