Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio-controlled vehicles require direct physical intervention for attaching and detaching attachments, posing safety risks during operation, especially on steep slopes or under high loads, and are prone to connection failures.
Innovation Solution
A remotely operable connection system using hydraulic cylinders and mechanisms that allow attachment coupling and release without direct operator intervention, ensuring safety and stability even on extreme slopes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fixed connection systems (bolted connections) are used to attach attachments to the radio-controlled vehicle, then the connection strength is sufficient to handle high loads, but the operator must directly physically intervene to fix or free the attachment, creating safety risks especially on steep slopes or during jamming incidents
Solution Approach 1:
The patent replaces the traditional mechanical bolted connection system with a hydraulic connection system. The hydraulic cylinder uses fluid pressure to automatically engage and disengage the attachment from the vehicle, eliminating the need for manual bolt manipulation while maintaining strong connection forces capable of handling high loads and extreme operating conditions
Solution Approach 2:
The hydraulic cylinder acts as an intermediary mechanism between the operator and the attachment connection process. The operator controls the hydraulic system remotely, and the hydraulic fluid transmits the force needed to engage and disengage the connection, serving as a mediator that protects the operator from direct exposure to dangerous situations while still achieving the connection function
2Reliability
If manual bolted connections are used for attaching attachments, then the connection can be securely fixed, but the process requires direct physical intervention by the operator which is dangerous on high gradients and under high loads
Solution Approach 1:
The hydraulic connection system replaces manual mechanical operations with automated hydraulic actuation. The hydraulic cylinder provides consistent, reliable connection forces that match or exceed manual bolting reliability while completely eliminating operator exposure to harmful conditions such as steep slopes, high loads, and potential attachment jamming incidents
Solution Approach 2:
The hydraulic connection system is self-actuating through remote hydraulic control. Once the operator activates the hydraulic system remotely, the attachment automatically engages or disengages without requiring the operator to physically approach or manually manipulate connection components, making the system serve itself in the connection process while protecting the operator
3Stability of the object's composition
If a fixed connection system is used, then the attachment remains stable during operation, but the connection cannot be quickly released remotely when breakdowns or malfunctions occur
Solution Approach 1:
The connection system transitions from a static fixed connection to a dynamic controllable connection. The hydraulic cylinder can maintain a stable locked connection during normal operation, then quickly transition to a released state when needed, allowing the system to adapt between stability and rapid release based on operational requirements
Solution Approach 2:
The hydraulic connection system enables periodic engagement and disengagement of the attachment through remote control. The attachment can be securely connected for extended periods of stable operation, then quickly disconnected when breakdowns occur, allowing for efficient replacement of attachments without prolonged exposure to dangerous conditions
4Ease of operation
If hydraulic connection mechanisms are used for remote attachment coupling, then operator safety is improved by eliminating direct physical intervention, but the device complexity increases due to additional hydraulic components
Solution Approach 1:
The hydraulic connection system serves multiple functions: it provides strong connection forces, enables remote operation, allows quick release, and maintains stability during operation. By consolidating these multiple functions into a single hydraulic mechanism rather than separate systems for each function, the overall complexity is managed while achieving comprehensive operator safety and operational flexibility

AI summary
The present invention is related to a method for coupling an attachment to a radio-controlled vehicle by means of a connection system having a support, an attachment-holder unit and a coupling unit. The support is fixed to a radio-controlled vehicle and the attachment-holder unit is fixed to the attachment. The coupling unit is automatically operable, in particular it is remotely operable, without the direct intervention of an operator to selectively connect or disconnect the support and the attachment-holder unit to/from each other.
