Swingable Energization Coupler for Stable Railway Model Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing model energization couplers face instability in energization due to design restrictions when dealing with tight curves, leading to potential non-energization states, especially in N-gauge railway models with small coupling parts and tight radii.
Innovation Solution
A model energization coupler design featuring a support member with swingable energization parts that include contact points for stable power collection, allowing for detachable engagement regardless of orientation and accommodating curvature changes, thereby maintaining stable energization without hindering the coupling function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the coupling part body is made to perform both coupling and energization functions, then the device complexity is reduced, but the reliability of energization deteriorates due to unstable contact on curved rails
Solution Approach 1:
The invention divides the coupling system into two independent parts: a coupling part for mechanical coupling and a separate energization part for electrical connection. The energization part includes contact points that can independently contact the coupling partner's contact points, ensuring stable energization without interfering with the coupling function. This segmentation resolves the contradiction by allowing each component to optimize its specific function rather than compromising both functions in a single integrated structure.
2Adaptability or versatility
If the coupling part is designed for tight curve accommodation, then the adaptability improves, but the energization contact stability deteriorates
Solution Approach 1:
The energization part is designed with dynamic characteristics, allowing it to swing or move independently to maintain contact between contact points during coupling operations on curved rails. This dynamic design enables the contact points to adapt to positional variations caused by curve accommodation while maintaining stable electrical connection, resolving the contradiction between curve adaptability and contact stability.
3Ease of operation
If the coupling mechanism is made movable for detachment, then the ease of operation improves, but the energization reliability deteriorates due to design restrictions
Solution Approach 1:
By separating the coupling mechanism from the energization mechanism, the invention allows the coupling part to be freely movable for easy attachment and detachment operations, while the energization part maintains its own stable contact path. The independent design of the energization part with dedicated contact points ensures that energization reliability is not compromised by the movability requirements of the coupling mechanism.

AI summary
In a model coupler that detachably couples vehicles, energization between the vehicles in train organization is stabled regardless of curvature of a rail. A support member is swingable in line with the coupling part by extending from an attachment base side attached to a model vehicle toward a front end side facing the coupling partner and providing a front end under the coupling part. One energization part is attached to the support member and includes a first contact point formed on the attachment base side and a second contact point formed on the front end side. The first contact point is in contact with a first power collection member of the model vehicle, and the second contact point is in contact with a fourth contact point of the other energization part of the coupling partner.
