Innovation Solution
A prefabricated vehicle design featuring a body module and a platform module that can be connected and separated using a magnetic fastening system, allowing for easy configuration and reconfiguration based on purpose, with physical fastening and magnetic coupling for stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a completed vehicle is manufactured for each specific purpose, then the vehicle can be used for its intended purpose, but manufacturing costs and inventory costs increase
Solution Approach 1:
The vehicle is divided into separate modules: a platform module (chassis, powertrain) and a body module (passenger compartment). These modules can be independently manufactured and then assembled through physical fastening and magnetic coupling, allowing different body modules to be attached to the same platform module for different vehicle purposes.
Solution Approach 2:
The platform module is designed as a universal base that can support multiple types of body modules. The standardized connecting portions with magnetic modules and armatures enable the same platform to be configured for different vehicle types (e.g., passenger vehicle, freight vehicle) by simply changing the body module.
2Adaptability or versatility
If a completed vehicle is manufactured for each specific purpose, then the vehicle can be used for its intended purpose, but inventory processing costs increase
Solution Approach 1:
By segmenting the vehicle into platform and body modules, the system eliminates the need to manufacture and store complete vehicles for each purpose. Only the body module needs to be changed for different configurations, significantly reducing inventory complexity and associated processing costs.
3Ease of operation
If a magnetic fastening system is used to connect body module and platform module, then ease of replacement and reconfiguration is improved, but device complexity increases
Solution Approach 1:
The traditional mechanical fastening system (bolts, nuts, welds) is replaced with a magnetic fastening system. The magnetic module and armature create strong magnetic attraction forces that securely hold the body module to the platform module, enabling easy attachment and detachment without complex mechanical operations.
Solution Approach 2:
The magnetic force strength can be controlled by adjusting electrical parameters (current, voltage) supplied to the magnetic module. This allows dynamic control of the fastening force, enabling easy replacement when needed while maintaining secure connection during operation.
4Reliability
If physical fastening and magnetic coupling are used together, then coupling stability is improved, but device complexity increases
Solution Approach 1:
The invention combines two different fastening mechanisms (physical fastening and magnetic coupling) into a unified system. The physical fastening provides structural alignment and initial positioning, while the magnetic coupling provides secure holding force and easy release capability, creating a synergistic fastening system.
