Construction Equipment Console Positioning via Cable-Pulley Gearing
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Reliability
If a structural gearing system with shaft is used, then reliability under harsh conditions is improved, but device complexity increases
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.

AI summary
The invention relates to a position adjustment mechanism (100) that controls the mechanisms of construction equipment, said mechanism comprising of a control console (1), a base support (4), and a body (3) that is movable relative to said base support (4), said mechanism being located between the base supports (4), and said mechanism passing through the base supports (4), and said mechanism adjusting the location of the control console (1) relative to the driver, which is formed of a connector (5) allowing the said body (3) to rotate clockwise or anticlockwise, and said mechanism comprising a trigger (110) that shifts said body (3) to an idle mode, a transfer arm (120) that transfers movement of the said trigger (110), a coupling mechanism (130) that is in communication with said transfer arm (120), and shifts said body (3) to an idle mode or allows it to be retained in a desired position, and also a fixed gear (140) that is connected to said base support (4) on its 2 sidewalls, wherein said coupling mechanism (130) is engaged to said fixed gear when it switches to coupling position.
