Interchangeable Indenter Test Apparatus for Bending Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current test apparatuses are limited in their ability to perform multiple types of tests, such as three-point and four-point bending tests, on a single platform, requiring separate setups for different testing methods.
Innovation Solution
A test apparatus with a support base, a pressing unit, and a load measuring instrument that includes interchangeable first and second test indenters for performing three-point and four-point bending tests on a single test piece, allowing for selection of the appropriate indenter based on the test type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single test apparatus is designed to perform only one type of test (e.g., three-point bending test), then the device structure is simple and easy to manufacture, but the adaptability and versatility are limited
Solution Approach 1:
The pressing unit is designed with interchangeable indenters that can be selected based on the test type required. The same pressing unit can accommodate different indenter configurations (single indenter for three-point bending, multiple indenters for four-point bending), allowing one apparatus to perform multiple test types without requiring separate dedicated devices for each test method
Solution Approach 2:
The pressing unit is divided into modular components including the indenter assembly and supporting structures. The indenter can be configured with different numbers of pressing points (one or multiple) and arranged in different patterns, allowing the same basic structure to be segmented and reconfigured for different test requirements
2Productivity
If multiple test indenters are integrated into a single pressing unit, then the productivity and efficiency are improved by eliminating the need for multiple setups, but the device complexity increases
Solution Approach 1:
The pressing unit incorporates movable and adjustable components that allow the indenter configuration to be changed dynamically based on test requirements. The indenter assembly can be repositioned, reconfigured, or replaced during operation, enabling the system to adapt between different test types (three-point or four-point bending) without requiring complete disassembly or replacement of the entire pressing unit
Solution Approach 2:
The indenter components are nested within the pressing unit structure, with the indenter assembly contained within the supporting framework. This nested arrangement allows multiple indenter configurations to be housed within a single compact pressing unit, reducing the space and complexity required compared to having separate dedicated pressing units for each test type

AI summary
A test apparatus includes a support base that supports an undersurface of a chip, a pressing unit that presses the chip supported by the support base, and a load measuring instrument that measures a load applied when the pressing unit presses the chip. The pressing unit includes a first test indenter that performs a three-point bending test by pressing the chip supported by the support base and a second test indenter that performs a four-point bending test by pressing the chip supported by the support base, and the first test indenter and the second test indenter are configured to be selectable when the chip supported by the support base is pressed by the pressing unit.
