Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a computer mouse uses a fixed mechanical switch assembly, then it provides tactile click feel, but it consumes more power and reduces battery life

Engineering Contradiction:
Improvetactile click feelVSAvoidbattery life
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent implements a switch assembly that can dynamically change its operational state between mechanical contact and non-contact modes. The switch assembly includes a movable component that can be positioned to either physically contact the circuit board (providing tactile feedback) or be spaced apart (reducing power consumption). This dynamic configurability allows the system to adapt between tactile feedback mode and power-saving mode.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The switch assembly is designed as a separable component that can be independently adjusted or replaced. The switch assembly includes a first switch component and a second switch component that can be independently configured, allowing selective engagement with the circuit board. This segmentation enables flexible configuration where only necessary switch components are activated based on usage requirements.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a computer mouse uses a fixed switch assembly design, then it maintains structural simplicity, but it cannot meet different usage requirements for various scenarios

Engineering Contradiction:
Improvestructural simplicityVSAvoidusage scenario adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The switch assembly incorporates adjustable spacing between components, allowing the distance between the switch assembly and circuit board to be varied. This dynamic adjustment enables the same physical structure to provide different operational characteristics - closer spacing for tactile feedback applications and farther spacing for silent or power-saving applications.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The switch assembly is designed to perform multiple functions through a single unified structure. It can operate in mechanical contact mode for tactile feedback, non-contact mode for silent operation, and intermediate modes for varying power consumption. The universal design allows one switch assembly to replace multiple specialized assemblies, achieving versatility without proportionally increasing complexity.

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

3Adaptability or versatility

If a computer mouse uses a removable switch assembly with magnetic coupling, then it enables easy swapping for different configurations, but it increases device complexity

Engineering Contradiction:
Improveswitch assembly interchangeabilityVSAvoidmagnetic coupling mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical fastening mechanisms (screws, clips, or snap-fits) with magnetic coupling for attaching the switch assembly to the circuit board. The magnetic coupling includes a first magnetic component and a second magnetic component that attract each other to secure the switch assembly. This substitution eliminates complex mechanical assembly and disassembly operations, allowing users to simply snap the switch assembly into place and remove it by pulling, significantly easing the swapping process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
