Sliding Locking Assembly for Screwless Chassis Reattachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of separating and reassembling a chassis and mounting bracket in computer devices is tedious due to the need to remove screws one by one, and there is a risk of losing screws, making reassembly difficult.
Innovation Solution
A locking assembly with a sliding component and transmission group that uses a locking block and elastic member to secure the chassis frames, allowing for easy detachment and reattachment without screws, using a handle to facilitate movement and locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screws are used to secure the chassis and mounting bracket, then the connection strength is sufficient, but the assembly and disassembly process becomes tedious and time-consuming
Solution Approach 1:
The locking assembly is divided into multiple functional components: a locking block with locking surfaces, a sliding component for actuation, and a transmission group with locking members. This segmentation allows each component to perform a specific function, enabling quick locking and unlocking operations without requiring multiple screws to be manipulated individually.
Solution Approach 2:
The locking assembly transitions from a static screw-based connection to a dynamic sliding mechanism. The sliding component can move along the sliding slot to engage or disengage the locking block, providing rapid transition between locked and unlocked states, thereby reducing assembly and disassembly time.
2Reliability
If multiple screws are used to secure the mounting bracket, then the connection is reliable, but the risk of losing screws increases and reassembly becomes difficult
Solution Approach 1:
Multiple locking functions are merged into a single integrated locking assembly. Instead of using multiple separate screws that can be lost, the locking block with multiple locking surfaces works together with the sliding component and transmission group to provide reliable connection through one unified mechanism, eliminating the risk of losing individual fasteners.
Solution Approach 2:
The locking assembly is designed to be self-contained with all necessary components integrated into the single assembly unit. The elastic member provides automatic resetting capability, and the transmission group ensures proper engagement of locking members, making the system self-sufficient and eliminating the need to track multiple separate screws for reassembly.
3Productivity
If a locking mechanism is introduced to replace screws, then the assembly and disassembly process is simplified, but the device complexity increases
Solution Approach 1:
The locking assembly serves multiple functions within a single integrated structure: the locking block provides locking surfaces, the sliding component enables actuation, the transmission group transfers motion to locking members, and the elastic member provides resetting force. This multi-functionality achieves quick assembly and disassembly without requiring separate components for each function, thereby limiting the increase in overall device complexity.

AI summary
A locking assembly for locking a first frame to a second frame, comprising a shell, a sliding component, a locking block and a transmission. The shell for connecting to the first frame. The sliding component slidably connected to the shell, and a guiding slot is defined on the sliding component. The locking block rotatably connected to the shell, a clamping notch is defined on the locking block and exposed from a top side of the shell for clamping a locking member on the second frame. The transmission group is connected to the sliding component by the guiding slot, the transmission group is further connected to the locking block. The transmission group is configured to rotate the locking block to clamp or unclamp the locking member, when the sliding component slides along a first direction to guide the transmission group by the guiding slot.
