Push Button Assembly for Chassis Storage Device Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage device trays in industrial computers occupy significant internal space, hindering the miniaturization of chassis due to their standard size and fixed installation method.
Innovation Solution
A push button assembly with a holder, latch, resilient member, and pushing bracket is integrated into the chassis cover, allowing the storage device to be easily removed by sliding the pushing bracket to deform a bent portion of the engaging bracket, thus overcoming the blocking stopping portion, and enabling the storage device to be pulled out without occupying excessive space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional tray is used to fasten storage devices, then the storage devices can be easily installed and removed, but the tray occupies a lot of internal space of the chassis
Solution Approach 1:
The patent extracts the storage device directly from the chassis without using a separate tray. The storage device is fastened directly to the chassis using engaging brackets that can be actuated by a push button mechanism, eliminating the need for an intermediate tray component and thereby saving internal space.
Solution Approach 2:
The patent merges the functions of the tray and the fastening mechanism into a single integrated system. The engaging bracket serves both as the mounting structure and the fastening mechanism, combining what were previously separate components (tray for support and separate fasteners) into one unified structure attached directly to the chassis.
2Volume of stationary object
If a push button assembly with latch and resilient member is used, then the storage device can be easily removed without tray, but the assembly structure becomes more complex
Solution Approach 1:
The resilient member (spring) in the push button assembly provides automatic resetting functionality. When the button is pressed to release the storage device, the spring automatically returns the button to its original position, eliminating the need for a separate resetting mechanism and simplifying the overall assembly while maintaining ease of operation.
Solution Approach 2:
The push button assembly is segmented into distinct functional components: the button itself, the latch mechanism, and the resilient member. This segmentation allows each component to perform its specific function independently, making the assembly easier to manufacture, assemble, and maintain despite the increased functionality.
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
This solution effectively increases internal chassis space by replacing the conventional tray with a partition and engaging bracket configuration, allowing for easy removal of storage devices while maintaining a simple and affordable design.
Implementation Method 1
The resilient member is disposed in the chute and compressed between the abutting plate and the latch

AI summary
A push button assembly disposed on a cover has a push button hole, and includes a holder, a latch, a resilient member, and pushing bracket. The holder forms a chute with the cover. The holder has an abutting plate and a retaining structure. The abutting plate and the retaining structure are respectively located at first and second ends of the chute. The latch is slidably disposed in the chute and faces the push button hole. The retaining structure can prevent the latch from leaving the chute from the second end. The resilient member is disposed in the chute and compressed between the abutting plate and the latch. The pushing bracket is connected to the latch and extends away from the cover. The disclosure further discloses a chassis applying the push button assembly and an operating method of the chassis.
