Keyboard Key Mechanism Single-Step Assembly via Guiding Slopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional key mechanisms require two steps for assembly, which complicates the process and is inconvenient.
Innovation Solution
The key mechanism incorporates a base plate with guiding bases and barricades featuring guiding slopes, allowing the scissors linking assembly to be directly pressed onto the base plate, with guiding pillars and pillars being elastically deformed to secure position in one step.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional two-step assembly process is used, then the guiding pillars can be securely positioned, but the assembly process becomes complex and inconvenient
Solution Approach 1:
The patent combines two separate assembly steps into one integrated step. The guiding bases are designed with guiding slopes that allow the guiding pillars to be inserted and positioned simultaneously, eliminating the need for separate insertion and positioning operations. This merging of steps reduces assembly complexity while maintaining secure positioning through the slope-guided engagement mechanism.
Solution Approach 2:
The guiding bases are pre-configured with guiding slopes that prepare the path for the guiding pillars before actual assembly occurs. These pre-formed slopes guide the pillars into the correct position automatically during insertion, eliminating the need for separate positioning actions and simplifying the overall assembly process while ensuring reliable placement.
2Reliability
If the conventional two-step assembly process is used, then the guiding pillars can be securely positioned, but the assembly time increases
Solution Approach 1:
The patent merges the insertion and positioning operations into a single simultaneous action. The guiding slopes enable both functions to be achieved in one motion, reducing assembly time while maintaining secure positioning. This eliminates the sequential time loss associated with performing insertion and positioning as separate steps.
Solution Approach 2:
The guiding slopes allow the assembly process to skip intermediate adjustment steps by providing automatic guidance during insertion. The pillars are rushed directly into their final positioned state through the slope-guided path, eliminating time-consuming manual positioning adjustments and reducing overall assembly time while ensuring accurate placement.

Function Achieved in This Case
This simplifies the assembly process to a single step, enhancing the facilitation and efficiency of combining the scissors linking assembly with the base plate.
Implementation Method 1
The first guiding pillar is disposed in the first guiding base through the first barricade and is abutted between the first guiding base and the first barricade. The second guiding pillar is disposed in the second guiding base through the second barricade and is abutted between the second guiding base and the second barricade.
