Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If advanced rangefinder with multiple buttons is used to allow precise ballistic calculations, then measurement precision is improved, but device complexity increases and ease of operation deteriorates

Engineering Contradiction:

Solution Approach 1:

A single button on the rangefinder performs multiple functions including menu navigation, data entry, and profile management. The button can be pressed in different ways (single press, long press, combination with other buttons) to access different modes and functions, eliminating the need for multiple dedicated buttons while maintaining full functionality for precise ballistic calculations

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

Solution Approach 2:

The patent combines multiple control functions into a single button interface. Instead of having separate buttons for menu access, navigation, and data entry, all these functions are integrated into one button that can be operated in various ways to perform different tasks, simplifying the device while preserving precision capabilities

Inventive Principle:
Principle #5Merging (Combining)

Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The rangefinder includes pre-configured ballistic profiles stored in memory that automatically apply to different shooting scenarios. Users can select from pre-programmed profiles for different rifle/bullet combinations, eliminating the need for manual entry of complex ballistic data while still achieving precise calculations. The device serves itself by providing ready-to-use ballistic solutions

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Ballistic profiles and parameters are pre-configured and stored in the rangefinder's memory before use. Users can set up their specific rifle, bullet, and environmental parameters once, and the device stores these profiles for quick recall during shooting sessions, eliminating the need for repeated data entry while maintaining precision

Inventive Principle:
