Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fixing devices for expansion units in computers are cumbersome and difficult to install or remove due to limited space, requiring significant resources and time for development to improve their characteristics.
Innovation Solution
A fixing device featuring a substrate with a slot and an elastic fixing bracket that includes a force-receiving upper portion and a supporting lower portion, allowing the bracket to switch between open and fixing states for easy accommodation and release of expansion units, thereby simplifying installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixing and locking means are used to secure expansion units, then the expansion units are firmly fixed to the computer, but the device complexity increases and installation/removal becomes time-consuming
Solution Approach 1:
The fixing bracket changes its physical state between elastic deformation and elastic recovery, transitioning between open and fixing states. This parameter change allows the bracket to securely hold the expansion unit while remaining simple in structure and quick to operate.
Solution Approach 2:
The elastic fixing bracket automatically secures the expansion unit through elastic recovery after manual opening, eliminating the need for separate locking mechanisms. The bracket self-adjusts to maintain secure fixation without additional components.
2Reliability
If traditional locking means are used to fix expansion units, then the expansion units are securely fixed, but the time required for fixing and detaching increases
Solution Approach 1:
The fixing bracket transitions from a static traditional locking mechanism to a dynamic elastic structure that can quickly switch between open and fixing states. This dynamic behavior enables rapid installation and removal while maintaining secure fixation through elastic recovery.
3Loss of time
If elastic fixing bracket is used to replace traditional fixing means, then the time and cost for fixing and detaching are reduced, but the fixing strength may be compromised
Solution Approach 1:
The elastic fixing bracket utilizes controlled elastic deformation as a key parameter change, allowing the material to temporarily deform during installation/removal and then recover to provide strong fixation. This parameter change enables both rapid operation and sufficient fixing strength.
Solution Approach 2:
The fixing bracket is made of elastic material that combines flexibility for easy operation with sufficient strength for secure fixation. The material properties are selected to balance both requirements, providing both speed and strength.
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 elastic fixing bracket allows for efficient clamping and detachment of expansion units, reducing time and cost by replacing traditional fixing methods and enhancing usability.
Implementation Method 1
When a force is applied to or released from the force receiving upper portion, the force receiving upper portion elastically deforms or elastically recovers
Implementation Method 2
When a force is applied to or released from the force receiving upper portion, the force receiving upper portion elastically deforms or elastically recovers

AI summary
A fixing device includes a substrate, a slot, a fixing bracket. The slot is disposed on the substrate, and a first end of an expansion unit is inserted in the slot. The fixing bracket is disposed on the substrate, in which the fixing bracket includes a force receiving upper portion and a supporting lower portion. An accommodating space is defined between the force receiving upper portion and the supporting lower portion. When a force is applied to or released from the force receiving upper portion, the force receiving upper portion elastically deforms or elastically recovers. Therefore, the fixing bracket switches between an open state and a fixing state for enabling the accommodating space to selectively accommodate a second end of the expansion unit.
