Solution Overview

Problem

Cables for transmitting energy and signals to weapons mounted on vehicles without a slip ring transmitter often interfere with the operator's view and mobility, and occupy valuable space inside the vehicle when they wrap around during rotation, limiting the aiming range and usability.

Innovation Solution

Implementing a dual-axis rotation system where the weapon's directional movement is decoupled from its barrel's movement, using a primary side pivot bearing for azimuthal movement and a secondary axis for horizontal rotation, with a gearbox-driven secondary pivot bearing to manage the weapon's position independently, reducing the space required for cable routing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cables are routed around the carriage with length compensation to enable rotation, then the carriage can rotate without cable entanglement, but the cables interfere with the operator's view and freedom of movement and take up a lot of free space

Engineering Contradiction:
Improvecarriage rotation capabilityVSAvoidspace occupied by cables
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The harmful element (cables) is extracted from the operational area by routing them through a dedicated cable guide system that separates them from the operator's workspace. The cable guide is positioned to lead cables away from the operator's view and movement path, effectively removing the interference while maintaining rotation capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A cable guide system acts as an intermediary between the rotating carriage and the fixed cable supply. This intermediary component manages cable routing through spiral formation and guided paths, enabling rotation while preventing cable entanglement and interference with the operator

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If cables are routed downwards with a spiral formation to enable rotation, then the carriage can rotate freely, but this causes a large area of interference inside the vehicle making it impossible for people to use this space

Engineering Contradiction:
Improvecarriage rotation rangeVSAvoidspace occupied by cable routing
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The cable routing is moved from the horizontal operational space to a vertical/different spatial dimension by routing cables along the carriage structure and through overhead or peripheral paths. This dimensional relocation allows the cables to occupy space that does not interfere with the operator's workspace or vehicle interior volume

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Area of stationary object

If a dual-axis rotation system is implemented to decouple directional movement from barrel movement, then the space needed for cable routing is reduced, but the device complexity increases

Engineering Contradiction:
Improvecable routing spaceVSAvoiddual-axis rotation system
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The rotation system is segmented into two independent axes: a primary axis for directional movement and a secondary axis for barrel orientation. This segmentation allows cables to be routed only with the primary axis rotation, reducing the space and complexity required for cable management while maintaining full operational capability

Inventive Principle:
Principle #1Segmentation

AI summary

The carriage (20) or tower has a weapon (1), a weapon pipe (2) and an upper carriage (3). A side rotary mount (10) is integrated, which rotates the weapon, with weapon pipe and upper carriage, around a vertical secondary axis (9). The side rotary mount is rotated opposite the primary axis (6) dependently or independently of the rotating motion of another side rotary mount (7).
