Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional molecular modeling kits are used, then models can be constructed with appropriate angles and distances, but the kits have limited resources requiring disassembly and reassembly for different models
Solution Approach 1:
The invention divides the molecular model into separate construction modules, each representing a specific atom type (carbon, hydrogen, oxygen, nitrogen, etc.). Each module contains pre-formed bonds extending from the central atom, allowing students to assemble complex molecules by connecting these modular units through magnetic or snap-fit interfaces, eliminating the need for numerous individual rod pieces.
Solution Approach 2:
The construction modules are designed with universal connection interfaces that work across all atom types. Each module can serve multiple functions: representing different elements (C, H, O, N, S, P, halogens), forming various bond geometries (tetrahedral, trigonal planar, linear), and connecting to multiple other modules. This universal design allows a single set of modules to construct any molecular structure.
2Productivity
If 3D printing pens are used to draw structures, then models can be created quickly, but it is difficult to manipulate the pen accurately in three dimensions
Solution Approach 1:
The construction modules are pre-designed and pre-assembled with correct bond angles and lengths before the student begins building. The modular components include pre-formed bond structures that extend from each atom center, eliminating the need for students to manually draw and measure bonds in 3D space, thus removing the difficulty of pen manipulation while maintaining quick assembly.
Solution Approach 2:
The construction modules serve as intermediaries between the student's intent and the final molecular model. Instead of directly drawing bonds with a 3D printing pen, students connect pre-fabricated modules that already embody the correct geometric relationships. The modules act as physical templates that guide the formation of accurate molecular structures without requiring precise 3D drawing skills.
3Adaptability or versatility
If 2D templates are used and assembled into 3D structures, then models can be created, but the process is time-consuming and models must be disassembled after use
Solution Approach 1:
The construction modules incorporate magnetic or snap-fit connection mechanisms that enable rapid assembly and disassembly. The dynamic connection system allows students to quickly build different molecular models by simply connecting and disconnecting modules, reducing the time required compared to traditional assembly methods while maintaining the ability to create various molecular structures.
Solution Approach 2:
The modular design allows students to disassemble models after use and store the individual modules for future use. Rather than disassembling and storing numerous small components, students recover a compact set of reusable modules that can be quickly reconfigured for different molecular structures, significantly reducing preparation time for subsequent activities.
4Manufacturing precision
If traditional 3D printing methods are used, then models can be produced, but the process is too time-consuming for in-class activities
Solution Approach 1:
The invention pre-segments the molecular structure into modular components with precisely engineered bond angles and lengths. Each module is manufactured with high precision before being distributed to students, allowing rapid assembly of accurate molecular models without requiring time-consuming 3D printing processes during class activities.
Solution Approach 2:
The construction modules are pre-manufactured with exact geometric specifications (bond lengths, angles, and three-dimensional orientations) before reaching the classroom. This preliminary fabrication of precise components eliminates the need for time-consuming 3D printing during instruction, enabling students to focus on assembling pre-precisioned modules to create accurate molecular models quickly.
