Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional globes are used for static display, then manufacturing is simple and cost is low, but user interaction is poor and experience is limited

Engineering Contradiction:
Improveuser interactionVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The globe is designed to perform multiple functions: it serves as both a traditional geographic display model and an interactive touch screen interface. The projection module enables the globe to display various geographic information dynamically, while the touch sensing module allows direct user interaction, making the device adaptable to different usage scenarios without requiring separate systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces traditional mechanical globe rotation and manual operation with electronic control systems. The processor controls the projection module to display geographic information based on touch inputs, voice commands, or camera recognition, substituting mechanical interactions with electronic signal processing and automated responses

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If projection module and processor are added to enable interactivity, then user engagement is improved, but device complexity increases

Engineering Contradiction:
Improvedisplay functionalityVSAvoidcomponent quantity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The projection module serves multiple purposes: displaying geographic maps, showing three-dimensional earth models, presenting augmented reality overlays, and displaying custom content. The same hardware components support various display modes and functions, reducing the need for separate specialized devices

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the globe structure with electronic components by integrating the projection module within the hollow sphere and embedding the processor in the support base. This merging of mechanical and electronic systems into a single unified device reduces overall system complexity compared to having separate interactive display devices

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If touch sensing module is integrated on the sphere, then physical interaction is enabled, but manufacturing precision requirements increase

Engineering Contradiction:
Improvetouch interactionVSAvoidmodule integration precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The touch sensing module is segmented into discrete functional units that can be independently manufactured and then assembled onto the globe surface. This segmentation allows for standardized manufacturing processes and simplifies the integration step, reducing the overall precision requirements compared to monolithic integration

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If camera module and motor are added for user positioning and orientation, then user experience is enhanced, but device complexity and power consumption increase

Engineering Contradiction:
Improveuser positioning capabilityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The motor-driven rotation system operates periodically rather than continuously, activating only when user positioning or orientation changes are detected. The camera module captures images at specific intervals or triggered by user proximity, reducing overall energy consumption while maintaining positioning capabilities

Inventive Principle:
Principle #19Periodic action
