Solution Overview

Problem

Existing position adjustment mechanisms for control consoles in construction equipment, such as those using gas springs, are prone to wire breakage and failure under harsh use conditions, lacking sufficient resistance and reliability.

Innovation Solution

A structural gearing system with a shaft guiding the gears and incorporating springs for position adjustment, allowing the console to operate in idle mode, is developed to address these issues, featuring a coupling mechanism with main and additional couplings, retaining springs, and idle springs for smooth and adjustable positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If gas springs are used for position adjustment, then position adjustment function is provided, but wire breakage and damper failure occur under harsh use conditions

Engineering Contradiction:
Improvereliability of position adjustment mechanismVSAvoidwire breakage and damper failure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the gas spring mechanical system with a cable-driven pulley system. The control console position adjustment is achieved through cables (32, 33) that wrap around pulleys (22, 23) mounted on the console (2) and anchor points (12, 13) on the vehicle body (1). This mechanical substitution eliminates the use of gas springs and their associated wire breakage and damper failure problems under harsh construction equipment operating conditions.

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

Solution Approach 2:

The patent extracts and removes the problematic gas spring component from the position adjustment mechanism. By eliminating the gas spring entirely and replacing it with a cable-pulley system, the source of wire breakage and damper failure is completely removed from the mechanism, leaving only the essential position adjustment function.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a structural gearing system with shaft is used, then reliability under harsh conditions is improved, but device complexity increases

Engineering Contradiction:
Improvedurability under harsh conditionsVSAvoidcomplexity of gearing system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the position adjustment mechanism into distinct functional components: cable-driven pulleys (22, 23) for movement, and a separate locking mechanism with gear (26) and locking lever (25) for position fixation. This segmentation allows each component to perform its specific function reliably without the complexity of an integrated gearing system with shaft, while maintaining durability under harsh construction equipment conditions.

Inventive Principle:
Principle #1Segmentation
