Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple batteries are used to power various accessories, then each accessory can operate independently, but the overall weight and complexity of the system increases

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent combines multiple battery power sources into a single centralized power source integrated into the rifle platform. This central power source distributes electrical power to multiple accessories through the accessory rail system, eliminating the need for each accessory to have its own battery while maintaining independent operation of each accessory.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The centralized power source serves multiple functions by powering various different accessories (optics, lasers, flashlights) through a universal interface. The accessory rail system provides a multi-functional platform that can accommodate different accessories while drawing power from the same central source, reducing overall system weight.

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

2Adaptability or versatility

If multiple batteries are carried for different accessories, then each accessory can be powered, but the field load and complexity of power management increases

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple separate battery management systems into a single centralized power management system. This system handles power distribution, voltage regulation, and accessory interface through a unified control architecture, significantly reducing the complexity of power management while maintaining the ability to power multiple different accessories.

Inventive Principle:
Principle #5Merging (Combining)

3Weight of moving object

If a centralized power source is used, then weight and complexity are reduced, but power distribution and communication infrastructure is required

Engineering Contradiction:
Core Design Contradiction:
Weight of moving objectVSDevice complexity

Solution Approach 1:

The accessory rail serves as an intermediary structure that integrates both mechanical mounting and electrical power/communication interfaces. This rail system acts as a mediator between the centralized power source and various accessories, providing a standardized interface that simplifies the power distribution infrastructure while enabling weight reduction.

Inventive Principle:
Principle #24Intermediary (Mediator)
