Elongated Material Testing With Combined Friction and Bending Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for performing friction and bending tests on elongated materials introduce external factors and vary test conditions due to the need to transfer materials between separate test apparatuses, leading to inconsistent results.
Innovation Solution
A single material test apparatus with a target holding portion, jig holding portion, and movement mechanism that applies both friction and bending loads to the test material without requiring transfer between apparatuses, using synchronized movements to minimize condition changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate dedicated test apparatus are used for friction test and bending test, then each test can be performed with specialized equipment, but test conditions vary and external factors are introduced when transferring materials between apparatus
Solution Approach 1:
The patent combines the friction test apparatus and bending test apparatus into a single integrated test system. The test material is held by a common holding portion, and a single load-applying jig performs both friction loading (through reciprocating motion) and bending loading (through perpendicular motion), eliminating the need to transfer materials between separate apparatus and ensuring consistent test conditions.
Solution Approach 2:
The load-applying jig is designed with multi-functionality to perform both friction testing and bending testing. The jig can apply friction loads by rubbing the test material during reciprocating motion and bending loads by moving perpendicular to the test material length, allowing a single apparatus to fulfill multiple testing functions that previously required separate dedicated equipment.
2Measurement precision
If materials are transferred between separate test apparatus, then specialized testing can be performed, but external factors are introduced and test conditions may vary
Solution Approach 1:
By merging the friction test and bending test into a single apparatus, the patent eliminates the material transfer step between apparatus. The test material remains in the same holding portion throughout both tests, preventing introduction of external factors during transfer and maintaining consistent test conditions for improved measurement precision.
3Adaptability or versatility
If multiple dedicated apparatus are used, then each test function is optimized, but manufacturing cost and apparatus size increase
Solution Approach 1:
The patent merges multiple test functions into a single apparatus structure, reducing the total number of apparatus that need to be manufactured and maintained. The shared holding portion and multi-functional load-applying jig reduce overall manufacturing costs while maintaining the capability to perform both friction and bending tests.
Solution Approach 2:
The load-applying jig is designed as a universal component that can perform both friction loading and bending loading functions. This multi-functionality reduces the need for separate specialized apparatus, thereby lowering manufacturing costs and reducing the overall footprint of the testing equipment while maintaining full test capability.
