Solution Overview
Problem
Current methods for checking the manufacturing quality of bicycle components, particularly those made from fiber composite materials, lack continuous control and are inefficient, often requiring destructive testing or high-cost, time-consuming non-destructive methods like X-ray or CT scans.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If X-ray or CT scanning is used to examine the internal structure of bicycle components, then measurement precision and reliability are improved, but loss of time and device complexity increase significantly
Solution Approach 1:
The patent replaces complex mechanical/X-ray imaging systems with a thermal imaging system that uses infrared cameras to detect heat distribution patterns. This substitution maintains measurement precision for quality assessment while dramatically reducing inspection time and complexity, as thermal images can be captured and analyzed in real-time during the heating process.
Solution Approach 2:
The patent changes the measurement parameter from structural density (X-ray/CT) to thermal response characteristics. By monitoring how different regions of the component heat up or cool down, the system can infer internal structure quality, material distribution, and potential defects without requiring time-consuming cross-sectional imaging.
2Measurement precision
If multiple sensors and complex examination procedures are used to detect defects, then measurement precision is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The patent replaces multiple physical sensors and complex examination equipment with a single thermal imaging camera system. The infrared camera captures thermal radiation patterns that reveal internal structure and defects, eliminating the need for multiple sensors, complex positioning systems, and lengthy examination procedures while maintaining high measurement precision.
Solution Approach 2:
The component itself serves as the indicator of its quality through its thermal response. By heating the component and observing its thermal behavior, the system uses the component's own physical properties (heat conduction, heat capacity) to reveal its internal structure and defects, eliminating the need for external complex measurement apparatus.
3Ease of operation
If visual inspection and weight measurement are used for quality control, then ease of operation is improved, but measurement precision and reliability worsen
Solution Approach 1:
The patent replaces simple visual inspection and weight measurement with thermal imaging technology. While the operation remains relatively simple (heating and imaging), the measurement precision is dramatically improved by visualizing internal structure, material distribution, and defects that are invisible to the naked eye and undetectable by weight alone.
Solution Approach 2:
The patent uses thermal imaging to convert temperature variations into visible color patterns. Different regions of the component display different colors based on their thermal response, allowing operators to easily identify defects, material inconsistencies, and structural issues through color variations in the thermal image, combining operational simplicity with high measurement precision.
