Solution Overview
Problem
Existing methods for detecting deformation in objects, such as transported goods, are cumbersome and require large-scale systems or special devices, and fail to measure hidden areas, leading to potential breakage or movement during transport.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera and image analysis method are used to detect deformation of transported objects, then deformation detection capability is improved, but device size increases significantly
Solution Approach 1:
The patent replaces the optical measurement system (camera and image analysis) with an electrical measurement system. By embedding electrically conductive flexible material in the transporting section, the system detects deformation through changes in electrical characteristics (resistance, capacitance, or conductance) rather than optical images, thereby reducing device size while maintaining detection capability
Solution Approach 2:
The patent introduces an intermediary substance - the electrically conductive flexible material - that mediates between the transporting section and the detection system. This material converts mechanical deformation into electrical signal changes, enabling compact detection without requiring large-scale optical systems
2Measurement precision
If optical methods using a camera are used to detect deformation, then deformation measurement is improved, but hidden areas cannot be measured
Solution Approach 1:
The patent replaces optical detection with electrical detection that can penetrate and sense deformation throughout the entire transporting section, including hidden areas. The electrically conductive flexible material provides continuous electrical pathways that reflect deformation anywhere within the embedded region, eliminating the line-of-sight limitation of optical methods
Solution Approach 2:
The electrically conductive flexible material serves multiple functions: it provides structural support for the transporting section, enables electrical signaling for detection, and can be embedded in any configuration including hidden areas. This multi-functionality allows the same material to be used throughout the entire transporting section for comprehensive detection
3Measurement precision
If strain sensors are used to detect rigid body deformation, then detection accuracy is improved, but the sensors cannot be used in products requiring flexibility
Solution Approach 1:
The patent changes the physical state of the detection material from rigid (traditional strain sensors) to flexible (electrically conductive flexible material). By using materials like conductive polymers, metal foils, or conductive fluids embedded in flexible substrates, the system maintains deformation detection accuracy while adapting to flexible transporting sections that bend and deform
Solution Approach 2:
The patent employs composite materials combining flexible substrates with electrically conductive additives. Examples include flexible circuits with conductive traces, polymer matrices with conductive particles, or liquid conductive compounds embedded in flexible materials. These composite structures provide both flexibility and electrical conductivity for accurate deformation detection
