Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional denture test apparatuses lack stability during clamping, leading to shaking and inaccurate testing, particularly in measuring tensile strength, and require multiple devices for different tests, resulting in low efficiency.
Innovation Solution
A test apparatus with a carrying mechanism, internal support mechanism, stop mechanism, drive mechanism, and transmit mechanism, utilizing a threaded shaft and damping bearing to stabilize the denture during testing, allowing for simultaneous testing of tensile and hardness without re-clamping, and incorporating a hardness test mechanism with a camera for precise measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional pressing plates are used to clamp the denture, then the structure is simple, but the clamping stability is poor causing shaking during test
Solution Approach 1:
The clamping mechanism is divided into multiple components: pressing plates, threaded shafts, damping bearings, and internal support members. Each component performs a specific function - the threaded shafts provide adjustable clamping force, the damping bearings reduce vibration and shaking, and the internal support members stabilize the denture from within. This segmentation allows the system to achieve high clamping stability while maintaining reasonable structural complexity through modular design.
2Productivity
If multiple test devices are used for different tests, then each test can be performed accurately, but the test efficiency is low due to moving and re-clamping
Solution Approach 1:
The test apparatus is designed as a multi-functional integrated system that can perform both hardness testing and tensile strength testing on the same denture sample without requiring relocation. The apparatus includes a pressing mechanism for hardness testing and a pulling mechanism for tensile strength testing, both integrated into the same clamping system. This allows sequential performance of multiple tests on the same sample, significantly improving test efficiency while maintaining operational convenience through a unified control interface.
3Adaptability or versatility
If the denture is moved between test devices, then different test functions can be achieved, but the operation steps increase and time is lost
Solution Approach 1:
The apparatus merges multiple testing functions into a single integrated system. The hardness testing mechanism and tensile strength testing mechanism are combined in one apparatus, sharing common components such as the clamping system, positioning mechanism, and control system. This merging eliminates the need to move the denture between separate devices, reducing operation steps and time loss while maintaining the versatility to perform both test types on the same sample.
