Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional energization elements are used in biocompatible medical devices, then the devices can perform required functions, but the size and complexity of the energization elements do not meet the compact requirements of modern implantable devices
Solution Approach 1:
The patent transitions from planar (2D) energization elements to three-dimensional (3D) structures by forming conductive traces and active elements on a three-dimensional surface. This dimensional change allows the energization element to utilize the surface area of a 3D substrate, significantly reducing the overall volume while maintaining the required energy storage and delivery capabilities, thus achieving compact size without compromising reliability
Solution Approach 2:
The patent applies different materials and structures to different regions of the energization element. Conductive traces are formed in specific patterns on the three-dimensional surface, active elements are deposited only where needed, and biocompatible sealing material is applied to encapsulate the active components. This localized approach optimizes each region for its specific function while minimizing overall material usage and device size
2Volume of moving object
If the size of energization elements is reduced to meet device constraints, then compactness is achieved, but the energy capacity and performance may be insufficient
Solution Approach 1:
By utilizing a three-dimensional surface for conducting traces and active elements, the patent increases the effective surface area available for energy storage and delivery without increasing the overall device volume. This allows more energy capacity to be packed into a smaller space, resolving the contradiction between compact size and energy capacity
Solution Approach 2:
The patent employs composite structures combining conductive materials for traces, active energy-storing materials, and biocompatible sealing materials. This composite approach allows optimization of each material's properties for its specific function while achieving high energy density in a compact form factor
3Volume of moving object
If complex three-dimensional structures are used to achieve compact energization elements, then size requirements are met, but the manufacturing complexity increases
Solution Approach 1:
The patent forms the three-dimensional substrate and conductive trace patterns before depositing the active elements. This preliminary structuring creates a ready-made template that guides subsequent material deposition, simplifying the manufacturing process compared to attempting to form complex 3D structures in a single step or to assemble multiple separate components
4Object-affected harmful factors
If biocompatible materials are used to seal active elements, then safety and compatibility are improved, but the manufacturing process becomes more challenging
Solution Approach 1:
The patent combines the sealing function with the structural encapsulation of the three-dimensional substrate. The biocompatible material serves both as a sealant and as part of the overall device structure, eliminating the need for separate sealing steps and simplifying manufacturing while ensuring biocompatibility
