Notebook Input Module Quick-Release Mounting Without Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of disassembling or assembling the keyboard and touchpad in a notebook computer is time-consuming and labor-intensive due to the use of multiple screws, which increases manufacturing costs and resource consumption.
Innovation Solution
An electronic device with a quick-detaching engaging mechanism that allows the input module to be mounted and fixed using a positioning post and structure, facilitated by an auxiliary tool to release the engagement restriction, reducing the need for screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws are used to fix the input module, then the connection strength is improved, but the disassembly time and labor intensity increase
Solution Approach 1:
The fixing mechanism is segmented into a positioning post structure and a corresponding positioning structure, allowing the input module to be detached without requiring multiple screws. The positioning post engages with the positioning structure to provide sufficient connection strength while enabling quick disassembly by simply removing the positioning post.
Solution Approach 2:
The patent extracts the screw fastening mechanism and replaces it with a positioning post system. The positioning post is inserted through a through-hole in the input module to engage with the positioning structure on the housing, eliminating the need for screws and associated fastening operations.
2Strength
If multiple screws are used to fix the input module, then the connection strength is improved, but the manufacturing cost and resource consumption increase
Solution Approach 1:
The patent removes the screw components from the assembly, reducing part count and manufacturing complexity. The positioning post and positioning structure provide adequate connection strength without requiring threaded holes, washers, or separate fastening operations, thereby lowering manufacturing cost and resource consumption.
Solution Approach 2:
The positioning post serves multiple functions: it provides structural support, ensures proper positioning of the input module, and enables quick attachment and detachment. This multi-functionality replaces what would traditionally require multiple separate components including screws, reducing overall manufacturing complexity and cost.

AI summary
An electronic device that includes a housing, a positioning structure and an input module is provided. The housing has a top, a mounting region located on the top, a bottom relative to the top, and a disassembling region located on the bottom. The positioning structure corresponding to the disassembling region is disposed on an inside of the housing. The input module is detachably mounted on the mounting region and is provided with a positioning post. The positioning post is inserted into the inside of the housing from the mounting region to engage with the positioning structure in order to mount and fix the input module on the housing. An engagement restriction of the positioning structure to the positioning post is adapted to be released through an auxiliary tool to detach the input module from the housing.
