Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling electronic devices on circuit boards, such as M.2 solid state disks, are inefficient due to the complexity and time-consuming process of using screws, which can also lead to lost screws during assembly.
Innovation Solution
A circuit board fixing base with an elastic locking arm that deforms to securely lock the electronic device onto the carrier, eliminating the need for screws and allowing for easy assembly and disassembly by pressing down on a guiding slope, featuring a locking body and a guiding slope for deformation and reset functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to lock the electronic device onto the circuit board, then the connection is stable and reliable, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The patent extracts the screw fastening mechanism from the assembly process and replaces it with an elastic locking arm that integrates directly into the fixing base. This eliminates the need for separate screw components and manual screwing operations, thereby improving assembly efficiency while maintaining connection reliability through the elastic locking mechanism
Solution Approach 2:
The elastic locking arm is designed to automatically lock the electronic device onto the circuit board through its own elastic deformation, without requiring external fastening tools or additional fastening operations. The arm's elasticity enables it to self-adjust and secure the connection, improving both assembly speed and reliability
2Reliability
If screws are used for fastening, then the electronic device can be securely locked, but the small screws are easily lost during assembly
Solution Approach 1:
The patent merges the fastening function into the fixing base structure itself through the elastic locking arm, eliminating separate screw components. The locking arm is integrated with the base and works as a unified mechanism, preventing the loss of small fastening components while maintaining secure fastening capability
Solution Approach 2:
The elastic locking arm is designed as a durable, reusable component that replaces disposable or easily lost screws. Its elastic material and integrated design ensure it remains attached to the fixing base throughout assembly and disassembly operations, eliminating the frustration of losing small fastening components
3Productivity
If an elastic locking arm is used instead of screws, then assembly becomes faster and easier, but the locking mechanism becomes more complex
Solution Approach 1:
The patent employs an elastic locking arm made of flexible material that utilizes elastic deformation to achieve locking and unlocking functions. This flexible component replaces complex mechanical locking systems with a simple elastic mechanism that can be easily actuated by pressing, reducing overall device complexity while improving assembly speed
Solution Approach 2:
The locking mechanism operates by changing the elastic parameter (deformation) of the locking arm rather than through complex mechanical movements. By pressing the electronic device, the elastic arm deforms to lock, and releasing it allows automatic unlocking through elastic recovery, simplifying the mechanism while maintaining functionality

AI summary
A circuit board fixing base comprises a fixing base fixed on the electric circuit board. The fixing base is configured with carrier for carrying the electronic device and elastic locking arm located beside the carrier. The upper end of the elastic locking arm has a locking body to catch the electronic device so as to lock the electronic device on the carrier. Between the locking body and the carrier, a locking space is formed to lock the electronic device. The upper end of the locking body is configured with a guiding slope. When the electronic device is pressed on the guiding slope, the upper end of the elastic locking arm will be bent outward. The electronic device can be locked on the fixing base simply by pressing down the other end of the electronic device.
