Portable Evaluation Device for Pre-Owned Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing evaluation systems for pre-owned electronic devices are limited by space constraints, cost, and the need for fixed infrastructure, making them inaccessible for convenient evaluation, especially for devices of varying sizes and in locations away from stores.
Innovation Solution
A portable electronic device, such as a smartphone or tablet, is transformed into a portable evaluation device using software applications for imaging and automated machine-to-machine testing, overcoming challenges like device pairing, fraud prevention, and varying camera quality and lighting environments through techniques like QR code security challenges and mobile lighting source techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable electronic device is used to perform evaluation, then accessibility and convenience are improved, but evaluation accuracy and reliability may deteriorate
Solution Approach 1:
A remote server acts as an intermediary between the portable evaluation device and the evaluation system. The server receives evaluation data from the portable device, processes it through sophisticated algorithms, and provides comprehensive evaluation results. This intermediary approach allows simple portable hardware to achieve reliable evaluation accuracy by leveraging server-side computing power.
Solution Approach 2:
The patent replaces complex mechanical evaluation equipment with software-based evaluation methods running on portable devices. Instead of using specialized physical testing machinery, the system uses software applications that leverage the portable device's existing sensors and processing capabilities, substituted by remote server processing for comprehensive analysis.
2Reliability
If fixed infrastructure is used for evaluation, then evaluation accuracy is improved, but device portability and flexibility deteriorate
Solution Approach 1:
The patent extracts the core evaluation functionality from fixed infrastructure and implements it through portable electronic devices. By removing the evaluation system from fixed locations and embedding it in portable devices, the system achieves both accuracy (through server processing) and portability (through mobile hardware).
Solution Approach 2:
The portable electronic device serves multiple functions: it acts as the evaluation interface, data collection device, communication channel, and result display terminal. This multi-functional approach eliminates the need for separate fixed infrastructure while maintaining evaluation accuracy through server-based processing.
3Reliability
If sophisticated evaluation equipment is used, then evaluation accuracy is improved, but cost and infrastructure requirements deteriorate
Solution Approach 1:
The patent creates a virtual copy of the evaluation system through software applications running on portable devices. Instead of requiring physical sophisticated equipment, the system uses software that replicates evaluation functionality and leverages remote server resources to provide accurate results without complex local infrastructure.
Solution Approach 2:
The system replaces complex mechanical evaluation equipment with software-based evaluation methods. The portable device runs evaluation software that communicates with a remote server, substituting physical sophisticated equipment with digital processing power available through network connections.
