Solution Overview
Problem
Existing test apparatuses for impact resistance testing of electronic devices, such as display devices, face challenges in ensuring accurate and reliable results due to inconsistencies in dropping the falling body and deformation during the test, leading to reduced accuracy and increased test time.
Innovation Solution
A test apparatus with a position guide part and a falling body providing part, which includes an insertion module, a support module, an opening and closing module, and a laser module to mark the drop position accurately, allowing for precise control of the falling body's position and type, and the use of a rotation falling body providing part to reduce mounting time and improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual dropping method is used, then operation flexibility is maintained, but test reliability and accuracy deteriorate due to inconsistencies in dropping position and deformation
Solution Approach 1:
The patent replaces the manual mechanical dropping operation with an automated falling body providing part that includes an insertion module, support module, and opening and closing module. This automated mechanical system ensures consistent dropping position and force, eliminating the reliability issues associated with manual operation while maintaining controlled mechanical action.
Solution Approach 2:
The falling body providing part is designed to automatically position and release the falling body without requiring manual intervention for each test. The opening and closing module autonomously controls the release mechanism, and the laser module automatically marks the dropping position, enabling the system to service itself through automated operations.
2Measurement precision
If precise position control is implemented using laser marking, then dropping accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces a laser module that radiates a laser beam to mark the precise dropping position on the test object. This optical positioning system replaces complex mechanical measurement and positioning mechanisms, achieving high precision dropping position control through laser marking while avoiding the complexity of mechanical measurement systems.
3Adaptability or versatility
If multiple falling bodies are tested sequentially, then test comprehensiveness is improved, but test time increases
Solution Approach 1:
The falling body providing part is designed to pre-position multiple falling bodies in the insertion module before the test sequence begins. The support module holds multiple falling bodies ready for release, allowing the system to quickly switch between different falling body types without requiring time-consuming manual repositioning, thus maintaining test versatility while improving efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus ensures accurate and reliable impact resistance testing by marking the drop position with a laser, compensating for falling body deformation, and automating the test procedure, thereby improving accuracy and reducing test time and complexity.
Implementation Method 1
a laser module which radiates a laser beam to the insertion module to mark a position to which the falling body is provided
Implementation Method 2
a falling body providing part which provides a falling body to a predetermined position; the opening and closing module controls a drop of the falling body
