Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual replacement of probe cleaning paper is used, then operation simplicity is maintained, but productivity is reduced and cleaning precision deteriorates due to bubble formation and uneven application
Solution Approach 1:
The system performs self-service through automated mechanisms. The flattening roller automatically applies cleaning material to the probe card, and the removal roller automatically removes used cleaning material, eliminating the need for manual intervention and enabling continuous operation without human labor
Solution Approach 2:
Manual mechanical operations are replaced with automated mechanical systems. The manual action of replacing cleaning paper is substituted by a coordinated system of rollers (flattening roller and removal roller) that automatically perform the cleaning material application and removal functions
2Device complexity
If manual replacement of probe cleaning paper is used, then device complexity is low, but manufacturing precision deteriorates due to uneven application and bubble formation
Solution Approach 1:
The flattening roller serves as an intermediary between the cleaning material supply and the probe card. It mediates the application process by rolling the cleaning material onto the probe card surface, ensuring uniform distribution and eliminating bubbles that would occur with direct manual placement
Solution Approach 2:
The imprecise manual placement mechanism is replaced with a controlled mechanical rolling system. The flattening roller provides consistent pressure and motion to evenly apply cleaning material, while the removal roller precisely removes used material, both replacing the unpredictable manual operation
3Extent of automation
If manual cleaning paper replacement is used, then automation extent is low, but productivity is reduced due to slow operation speed
Solution Approach 1:
The system achieves self-service automation where the cleaning process continues without human intervention. The flattening roller continuously supplies fresh cleaning material and the removal roller continuously removes used material, creating an autonomous maintenance cycle that maximizes productivity
Solution Approach 2:
The cleaning process becomes continuous through the automated roller system. While manual replacement involves stop-start operations, the automated system maintains continuous action with the flattening roller constantly applying material and the removal roller constantly removing used material, eliminating downtime and maximizing maintenance 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 solution prevents damage to probe cards by ensuring even cleaning material application and automates the removal process, enhancing maintenance efficiency and effectiveness.
Implementation Method 1
the cleaning material is applied onto a surface of the cleaning plate by rolling and compressing via the flattening roller
Implementation Method 2
the cleaning material is removed from the cleaning plate by the removal roller after the completion of the cleaning
Implementation Method 3
the cleaning assembly cleans a surface of the probe card by contacting the cleaning material with the surface of the probe card

AI summary
A maintenance device for a testing equipment is provided, which includes: a cleaning assembly including a cleaning plate and a cleaning material; and a replacement assembly including a flattening roller and a removal roller. The cleaning material is applied onto an upper surface of the cleaning plate by rolling and compressing via the flattening roller, and the cleaning material is removed from the cleaning plate by the removal roller after the completion of the cleaning. The flattening roller is utilized to flatly apply the cleaning material to the cleaning plate, so as to avoid damage to the probe card of the testing equipment due to unevenness of the cleaning material, and the removal roller is used to automatically and quickly remove the used cleaning material to speed up the execution of maintenance work and improve the work efficiency of the maintenance device.
