Solution Overview

Problem

Existing bogies for magnetic levitation systems lack stability and adaptability during cornering, and the support structure contributes to the connection of levitation frames, which can lead to inefficiencies in weight distribution and space usage.

Innovation Solution

The bogie design features two rows of levitation frames with cross and longitudinal members that are connected to form spring systems, allowing the vehicle cabin to be supported more stably and enabling the levitation frames to pivot during cornering, with the cross and longitudinal members being spring-mounted to the levitation frames using conical and laminated springs, and the longitudinal members being rotatably connected to the cross members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If cross members and longitudinal members are rigidly connected to levitation frames, then structural strength is improved, but stability during cornering deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidstability during cornering
Core Design Contradiction:
StrengthVSStability of the object's composition

Solution Approach 1:

The cross members are designed to be pivotably connected to the levitation frames, allowing them to rotate relative to the frames during cornering. This dynamic connection enables the support structure to adapt to changing directional forces while maintaining structural integrity, resolving the contradiction between rigid strength and flexible stability.

Inventive Principle:
Principle #15Dynamics

2Weight of moving object

If multiple cross members are arranged between levitation frames, then weight distribution is improved, but space efficiency deteriorates

Engineering Contradiction:
Improveweight distributionVSAvoidspace efficiency
Core Design Contradiction:
Weight of moving objectVSVolume of moving object

Solution Approach 1:

The support structure is divided into multiple cross members spaced at different positions between levitation frames. Each cross member independently supports portions of the vehicle cabin, distributing the weight across multiple connection points while maintaining compact spacing that preserves space efficiency.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If longitudinal members connect multiple cross members, then adaptability during cornering is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability during corneringVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The longitudinal members serve dual functions by both connecting cross members to each other and providing pivotable connections to levitation frames. This merging of functions reduces the number of separate components needed while maintaining the adaptability required for cornering maneuvers.

Inventive Principle:
Principle #5Merging (Combining)
