Solution Overview

Problem

Conventional key structures with lifting mechanisms require numerous pivot portions for assembly, leading to a complicated structural design.

Innovation Solution

A simplified lifting mechanism using a first and second pivot element, where the first pivot element has a pivot hole and pivot shaft, and both pivot elements are configured to be pivoted to the same slide groove, reducing the number of pivot portions and simplifying assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional lifting mechanism with multiple pivot portions is used, then lifting function is provided, but structural complexity increases

Engineering Contradiction:

Improvelifting functionVSAvoidstructural complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple pivot portions into a single integrated pivot structure. The base plate includes a first pivot portion that integrates the functions of multiple separate pivot points, allowing the keycap to pivot relative to the base while reducing the total number of pivot components needed in the lifting mechanism.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The base plate's first pivot portion serves multiple functions simultaneously: it acts as a pivot point for the keycap, provides structural support, and enables the lifting motion. This multi-functional design eliminates the need for separate dedicated pivot components, simplifying the overall structure while maintaining the lifting function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple pivot portions are used for assembly, then lifting mechanism functions, but assembly complexity increases

Engineering Contradiction:

Improvelifting mechanism functionVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

By combining multiple pivot portions into one integrated first pivot portion in the base plate, the number of assembly steps is reduced. Instead of assembling multiple separate pivot components, the integrated design allows for simpler assembly while maintaining the reliable lifting mechanism function.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If conventional lifting mechanism is used, then keycap can be raised and lowered, but noise generation increases

Engineering Contradiction:

Improvekeycap lifting and loweringVSAvoidimpact noise

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent converts the potential harmful impact noise into a beneficial smooth pivoting motion. The first pivot portion is designed with features that guide the keycap's motion, converting what would be impact noise into controlled, low-noise pivoting action throughout the lifting and lowering cycle.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
