Simulated Rendering Engine for Device-Agnostic Clinical Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for developing and validating clinical instruments, such as electronic clinical outcome assessments (eCOA), are time-consuming and complex, requiring device-specific coding and separate instances for each device, which leads to increased computational overhead and complexity.
Innovation Solution
A computer-implemented method providing a device-agnostic environment with real-time rendering, using a simulated rendering environment on a user device to generate a rendered view of an instrument as if it were natively displayed on a base device, without requiring device-specific coding or separate instances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate instances for each device are used, then device-specific display accuracy is improved, but computational overhead and system complexity increase
Solution Approach 1:
The patent implements a universal rendering engine that can render instruments across multiple device types (mobile, tablet, desktop) using a single codebase. The rendering engine adapts to different device characteristics through configuration files rather than requiring separate instances, achieving multi-functionality while reducing system complexity.
Solution Approach 2:
The system changes parameters such as screen resolution, density, and layout configurations through parameter files rather than creating separate software instances. This allows the same rendering engine to adapt to different devices by loading appropriate parameter sets, maintaining display accuracy without increasing structural complexity.
2Adaptability or versatility
If device-specific coding and libraries are used, then adaptation to display characteristics is improved, but development time and coding complexity increase
Solution Approach 1:
The patent creates a universal instrument definition format and rendering engine that works across all device types. Device-specific adaptations are achieved through configuration parameters rather than device-specific coding, eliminating the need for separate codebases for mobile, tablet, and desktop platforms.
Solution Approach 2:
The system uses template-based instrument definitions that can be copied and adapted to different devices through parameter substitution rather than rewriting code. Instrument blueprints serve as reusable templates that generate device-specific instances through parameterization, significantly reducing development time.
3Measurement precision
If real-time rendering is implemented, then preview accuracy during construction is improved, but computational resources and processing time increase
Solution Approach 1:
The rendering engine implements selective rendering that focuses computational resources on critical display elements during preview mode. Rather than rendering the entire instrument with full fidelity, the system renders only essential portions at high accuracy while using simplified rendering for less critical areas, reducing overall computational burden while maintaining preview accuracy.

AI summary
A computer-implemented method for providing a device-agnostic environment with real-time rendering during instrument construction may include causing, via a processor of a user device, a graphical user interface of the user device to output a construction interface operable to edit contents of an instrument; causing, via the processor, the graphical user interface to output a rendered view of the instrument, wherein: the rendered view is generated via a simulated rendering environment of a base device operating on the user device, such that the simulated rendering environment interprets data of the instrument and generates the rendered view as if the instrument were natively displayed on the base device and while being agnostic to display characteristics of the user device; and the simulated rendering environment is configured to update the rendered view in real-time in response to adjustment to the construction interface.
