Used Bicycle Trading System with NDT Frame Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The South Korean market for used bicycles faces challenges in determining reasonable prices due to information asymmetry, trust issues, and limited payment options, leading to a decline in activity, particularly with Chinese CFRP-framed bicycles where cracks in the frame are difficult to identify externally.
Innovation Solution
A system and method for trading used bicycles that includes non-destructive testing (NDT) of the frame and appraisal of performance, providing a verified report and 360-degree virtual reality views, to determine a reasonable asking price and facilitate online transactions between sellers and buyers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct dealing through offline stores or online communities is used, then transaction flexibility is maintained, but information asymmetry and trust issues arise due to inability to verify bicycle condition
Solution Approach 1:
The patent introduces an intermediary verification system that acts as a trusted third party between buyers and sellers. The system includes a server that receives bicycle information from sellers, performs verification through multiple modules (frame crack detection, performance appraisal, pricing), and provides certified information to buyers. This intermediary structure resolves the trust issue by objectively verifying bicycle conditions without requiring direct interaction between parties.
Solution Approach 2:
The patent replaces manual inspection methods with automated verification systems. Instead of relying on visual inspection or physical examination by individual parties, the system uses automated modules including frame crack detection technology, performance appraisal systems, and algorithmic pricing mechanisms. This substitution of mechanical/manual verification with automated systems increases reliability while managing complexity through standardization.
2Measurement precision
If manual inspection and visual assessment are used, then verification simplicity is maintained, but measurement precision deteriorates due to inability to detect internal frame cracks
Solution Approach 1:
The verification system acts as an intermediary that performs specialized detection functions on behalf of buyers and sellers. The system includes specific modules for frame crack detection that use advanced technologies beyond visual inspection, performance appraisal capabilities, and automated pricing mechanisms. This intermediary approach enables precise measurement of bicycle conditions while managing the complexity of detection through standardized automated processes.
3Adaptability or versatility
If cash payment only is used, then transaction simplicity is maintained, but adaptability deteriorates due to limited payment options
Solution Approach 1:
The patent implements a universal payment system that supports multiple payment methods including cash, electronic payments, and other transaction types. The verification server and transaction platform are designed to handle diverse payment scenarios, making the system adaptable to different user preferences and requirements. This multi-functional payment capability increases versatility while the underlying standardized architecture manages the associated complexity.
