Probe Card Container with Rollers for Handling and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional probe card containers are heavy and difficult to handle due to increased weight, and pose safety risks when stored on high shelves that can oscillate, requiring specialized handling to prevent movement by oscillation or shock, which can transmit vibrations to the stored probe card.
Innovation Solution
A probe card container design featuring a main case with rollers for easy movement and a member for preventing movement, positioned on the mounting surface to absorb oscillations, allowing the container to be moved with less than half the normal force required, and incorporating an oscillation-absorbing material to reduce shock transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the probe card container is made heavy and solid to prevent movement on shelves, then stability is improved, but ease of operation deteriorates as it becomes difficult to handle
Solution Approach 1:
The container incorporates rollers that enable dynamic movement on demand. The container transitions from a static heavy structure to one with controlled mobility through the roller mechanism, allowing easy movement when needed while maintaining structural stability when stationary.
Solution Approach 2:
The roller acts as an intermediary element between the container and the supporting surface. It mediates the interaction by reducing friction during movement while the container's weight and structure provide stability when the roller is not engaged.
2Ease of operation
If the container is designed to be lightweight for easy handling, then ease of operation is improved, but stability deteriorates as it becomes more susceptible to movement by oscillation
Solution Approach 1:
The container uses a roller mechanism that provides dynamic stability. When the container is stationary, the roller can be positioned to engage with the supporting surface, preventing movement from oscillations while maintaining overall lightweight construction for ease of handling.
3Weight of moving object
If the container is made thin to reduce weight, then ease of operation is improved, but device complexity increases to achieve the required functionality
Solution Approach 1:
The container is designed as a thin-walled structure segmented into functional components. The roller mechanism is integrated as a separate module that can be attached to the thin container body, maintaining lightweight construction while adding the necessary movement control functionality without significantly increasing overall complexity.
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
Enables safe and precise handling of the container by reducing the force needed to move it by half, preventing unwanted movement due to oscillations or shocks, and minimizing vibrations transmitted to the probe card, resulting in a lighter and more manageable container.
Implementation Method 1
one or more rollers for assisting the movement of the main case
Implementation Method 2
one or more members for preventing the movement of the main case, the roller and the member being provided on a mounting surface of the main case
