External Charger Wheeled Platform With Blade-Lock Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transporting an external charger, a heavy object, at an unlevelled working site poses challenges due to the risk of the charger falling during movement, especially when the ground is uneven.
Innovation Solution
A wheeled platform with a pedestal, caster, and support pillars, featuring an engagement part that allows the blade of a working vehicle to lift and secure the charger, along with a movement regulating member to prevent wobbling and falling, enables easy transportation on uneven terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the external charger is transported manually or with conventional equipment on unlevelled ground, then the charger can be moved to the working site, but the risk of the charger falling or becoming unstable increases significantly
Solution Approach 1:
The patent introduces a blade as an intermediary component between the working vehicle and the external charger. The blade engages with the engagement part on the charger, serving as a mediator that allows the working vehicle to lift and transport the heavy charger without direct contact. This intermediary mechanism enables stable transport on unlevelled ground while reducing the operational difficulty of moving the charger.
Solution Approach 2:
The patent divides the transport system into distinct functional segments: the working vehicle, the blade, the engagement part, and the external charger. The engagement part itself is segmented into multiple components including the engagement hole, support pillars, and caster. This segmentation allows each component to perform its specific function independently, improving overall reliability while simplifying the transport operation.
2Reliability
If the engagement part is designed to securely hold the blade, then the charger is prevented from falling, but the complexity of the engagement mechanism increases
Solution Approach 1:
The engagement part is designed with dynamic characteristics that allow it to adapt to the blade's position and movements. The engagement hole is sized and shaped to accommodate the blade while providing natural mechanical constraints. The support pillars and caster work together to provide dynamic stability, allowing the system to maintain reliability without requiring complex fixed constraints or multiple locking mechanisms.
3Reliability
If the caster is positioned close to the ground for stability, then the charger is stable during transport, but the blade cannot be properly engaged to lift the charger
Solution Approach 1:
The patent resolves the spatial conflict between the caster and blade engagement by introducing a vertical dimension to the support structure. The support pillars extend vertically from the charger base to the engagement part, creating a multi-level structure. This allows the caster to remain close to the ground for stability while the engagement part is positioned at an elevated level, enabling the blade to engage and lift the charger without interference from the caster.

AI summary
An external charger is to be easily transported and securely prevented from falling during transport. A wheeled platform for external charger for transporting an external charger supplying electric power to a working vehicle driven by an electric motor includes: a pedestal where the external charger is placed; and a caster and a support pillar attached to the pedestal. The pedestal or the support pillar is provided with an engagement part which a blade of the working vehicle can be engaged with. The engagement part is configured in such a way that a movement regulating member preventing the blade from wobbling can be attached in a state where the caster is spaced apart from a ground by lifting the blade further from a state where the blade is engaged.
