Replaceable Key Module Structure for Simplified Keyboard Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboards have complex assembly processes and are not easily replaceable, leading to inconvenience and environmental impact when individual key structures are damaged.
Innovation Solution
A keyboard design featuring a key module with a connecting seat, connecting assembly, and elastic member, allowing for simplified assembly and easy replacement of individual key modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional keyboard assembly methods are used, then all key structures must be assembled individually onto the circuit board, but this results in a complicated and time-consuming assembly process
Solution Approach 1:
The patent divides the keyboard into independent key modules, where each key module includes a keycap, connecting assembly, elastic member, and base plate portion. This segmentation allows each module to be assembled and tested independently, then installed as a complete unit on the circuit board, dramatically simplifying the overall assembly process and improving productivity.
Solution Approach 2:
The patent combines multiple components (keycap, connecting assembly, elastic member, and base plate portion) into a single integrated key module. This merging eliminates the need to separately assemble and position each component on the circuit board, reducing assembly steps and complexity while maintaining full functionality.
2Ease of repair
If the entire keyboard is replaced when a key structure is damaged, then replacement is simple, but this is inconvenient and not environmentally friendly
Solution Approach 1:
By segmenting the keyboard into replaceable key modules, the patent enables users to replace only the damaged key module rather than the entire keyboard. Each key module is designed as an independent unit that can be easily removed and replaced by users, making repair simple and convenient while reducing waste.
3Reliability
If individual key structures have different replacement times based on usage frequency, then durability is optimized, but the inability to replace individual keys causes inconvenience
Solution Approach 1:
The patent implements segmentation by creating independently replaceable key modules, allowing users to replace only the frequently used keys that show wear while keeping less-used keys intact. This maintains optimal keyboard durability by replacing components based on actual usage patterns rather than forcing replacement of the entire keyboard.
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
Simplifies assembly and enables easy replacement of damaged keys, reducing environmental impact by minimizing the need to replace entire keyboards.
Implementation Method 1
The elastic member is disposed in the opening of the connecting seat, and the connecting seat presses against the elastic member

AI summary
A keyboard includes a circuit board module and a key module. The key module includes a keycap, a connecting seat, a connecting assembly and an elastic member. The connecting seat is disposed on the circuit board module. The connecting seat has an opening. One end of the connecting assembly connects to the keycap, and the other end connects to the connecting seat. The elastic member is disposed in the opening of the connecting seat, and the connecting seat presses against the elastic member.
