External Charger Platform With Blade Locking for Uneven Ground Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transporting an external charger, a heavy object, at uneven working sites poses challenges due to the risk of the charger falling during movement, as existing solutions do not effectively address the instability of the charger on unlevelled ground.
Innovation Solution
A wheeled platform with a pedestal, casters, 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, utilizing a U-shaped configuration for the engagement part and wheel stopper as the movement regulating member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the external charger is transported on an unleveled ground, then the charger can be moved to different working sites, but the charger may fall or become unstable during transport
Solution Approach 1:
The movement regulating member is nested within the engagement part structure. The engagement part has a U-shaped configuration that contains the movement regulating member inside it, allowing the regulating member to be integrated into the existing structure rather than being a separate external component. This nested arrangement enables the regulation function while maintaining the compact design needed for transport on uneven ground.
Solution Approach 2:
The movement regulating member acts as an intermediary between the engagement part and the blade. It mediates the interaction by providing a regulated engagement interface that prevents excessive movement while allowing the necessary lifting and securing actions. This intermediary component solves the stability problem without requiring fundamental changes to the charger or blade design.
2Reliability
If a dedicated movement regulating member is designed specifically for the engagement part, then the blade stability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The movement regulating member is designed with multi-functionality. It serves both as a structural component of the engagement part and as a regulation mechanism for blade stability. The U-shaped engagement part structure simultaneously provides the geometric constraint for blade engagement and houses the movement regulating member, eliminating the need for completely separate dedicated regulation components.
Solution Approach 2:
The movement regulating function is merged with the engagement part structure. Rather than being a separate dedicated component, the regulation capability is integrated into the engagement part through the U-shaped configuration that inherently provides movement regulation. This merging reduces the total number of parts and simplifies the overall device complexity while maintaining blade stability.
3Reliability
If the engagement part is designed with tight clearance to prevent blade movement, then the charger stability is improved, but the blade cannot be properly engaged or lifted
Solution Approach 1:
The engagement part design incorporates dynamic clearance characteristics. The U-shaped structure provides sufficient clearance when the blade is being engaged or lifted, allowing free movement and easy operation. However, when the blade is in the secured position, the movement regulating member provides dynamic constraint to prevent excessive movement. This dynamic approach to clearance management allows both easy engagement and stable transport.
Solution Approach 2:
Different regions of the engagement part have different clearance characteristics tailored to their specific functions. The upper portion of the U-shaped engagement part has larger clearance to facilitate blade engagement and lifting operations. The lower portion, where the movement regulating member is positioned, has tighter clearance to prevent blade movement during transport. This localized quality variation optimizes both operability and stability.

AI summary
An external charger is to be easily transported and securely prevented from falling during transport. A wheeled platform for external charger (1) for transporting an external charger (2) supplying electric power to a working vehicle driven by an electric motor includes: a pedestal (10) where the external charger (2) is placed; and a caster (12) and a support pillar (14) attached to the pedestal (10). The pedestal (10) or the support pillar (14) is provided with an engagement part (20) which a blade (122) of the working vehicle can be engaged with. The engagement part (20) is configured in such a way that a movement regulating member (30) preventing the blade (122) from wobbling can be attached in a state where the caster (12) is spaced apart from a ground by lifting the blade (122) further from a state where the blade (122) is engaged.
