Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a computer mouse is designed with fixed features for specific applications, then it provides optimized performance for that application, but it requires multiple purchases to accommodate different applications

Engineering Contradiction:
Improveperformance optimizationVSAvoidapplication adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mouse is divided into modular components including interchangeable keyplates, keyswitches, and scroll wheels that can be independently replaced. This segmentation allows users to customize the mouse for different applications without purchasing entirely new devices, resolving the contradiction between optimized performance and application adaptability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mouse chassis is designed as a universal platform that can accommodate multiple types of keyplates, keyswitches, and scroll wheels through standardized mounting interfaces. This multi-functionality enables a single mouse to serve multiple applications, eliminating the need for multiple specialized mice

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a computer mouse is designed with customizable features for different applications, then it reduces the need for multiple purchases, but it increases device complexity

Engineering Contradiction:
Improveapplication adaptabilityVSAvoidmodular component complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By segmenting the mouse into standardized modular components with simple mounting interfaces, the complexity is managed through modularity rather than integration. Each component remains relatively simple individually, but their combination provides extensive customization capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The universal chassis design with standardized mounting points provides a simple, consistent interface for multiple component types. This universality reduces the need for multiple specialized mounting systems, actually simplifying the overall device architecture while maintaining high adaptability

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A computer mouse comprising a chassis, a support beam with a first end configured to receive and secure a removable keyplate and a second end opposite the first end, and a keyswitch coupled to the chassis in an inverted configuration. In operation, the second end portion of the support beam moves up and contacts the keyswitch as the first end of the support beam is moved down. The keyswitch module may be operable to be coupled to the chassis at a plurality of different coupling locations, each coupling location operable to cause the second pressing force on the keyswitch to increase or decrease based on a distance from the keyswitch to the fulcrum. The keyplate can be non-destructively removeable from and couplable to the support beam without disassembly of the housing. The keyswitch can be non-destructively removeable from and couplable to the chassis without disassembly of the housing.
