Solution Overview
Problem
Conventional test devices for electrical components often cause damage and complicate the replacement process due to the need for securing elements, which can harm the components and make the testing process cumbersome.
Innovation Solution
A test device utilizing a component holding unit that establishes electrical contact through negative pressure within a pressure chamber, eliminating the need for mechanical securing means and allowing easy component replacement by using a movable component holding unit with a cylindrical cavity and pistons, along with a support surface for airtight connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a securing element is used to fix the component in the component holding unit, then reliable electrical contact is ensured, but the component may be damaged and the replacement process becomes complex
Solution Approach 1:
The patent removes the securing element from the system entirely. Instead of using mechanical fastening means to secure the component, the invention relies on the component holding unit's ability to maintain electrical contact through its design, eliminating the harmful securing element that causes component damage.
Solution Approach 2:
The patent replaces the mechanical securing system with a pressure-based system. A pressure element applies pressure to the component holding unit, which in turn maintains contact with the component, ensuring reliable electrical contact without mechanical fastening.
2Reliability
If a securing element is used to fix the component, then the component is securely held, but the replacement process becomes complex and time-consuming
Solution Approach 1:
The patent removes the securing element that complicates the replacement process. The component can be inserted into and removed from the component holding unit without actuating any securing mechanism, significantly reducing replacement time.
Solution Approach 2:
The component holding unit is designed to be dynamically adjustable through pressure application. The pressure element can apply pressure to secure the component during testing, and release pressure to facilitate quick removal, enabling fast component replacement.
3Ease of operation
If a pressure element is introduced to apply pressure to the component holding unit, then the component holding unit moves to establish electrical contact, but the device structure becomes more complex
Solution Approach 1:
The pressure element serves multiple functions: it applies pressure to the component holding unit to establish electrical contact, and simultaneously secures the component in place during testing. This multi-functionality reduces the need for additional separate mechanisms.
Solution Approach 2:
The patent combines the pressure application function with the component securing function. The pressure element's action on the component holding unit both establishes electrical contact and maintains component position, merging multiple functions into a single mechanism.
