Moving Cabin Cover Mechanism for Step-Free Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving object cabins face issues with foreign substances interfering with cover operations due to steps and require multiple devices for linear and rotational movements, leading to increased weight and cost.
Innovation Solution
A cover moving part that performs combined linear and rotational movements using a single operation member, comprising a forward/rearward moving member and rotational movement member, guided by a link member and rail, to simplify structure and reduce weight and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cover performs linear movement and rotational movement to remove the step, then the step is removed and foreign substance interference is eliminated, but the weight of the moving object increases and the unit cost increases due to requiring multiple devices
Solution Approach 1:
The patent combines linear movement and rotational movement functions into a single cover structure. The cover performs both linear displacement (to bridge the step) and rotational movement (to open/close) using one integrated component rather than separate devices, thereby eliminating foreign substance interference while avoiding weight and cost increases from multiple devices
Solution Approach 2:
The cover is designed as a multi-functional component that simultaneously performs linear movement (to overcome the step height difference) and rotational movement (to execute opening/closing operation). This universal design eliminates the need for separate linear actuator and rotational mechanism, reducing overall system weight and cost while solving the foreign substance problem
2Object-affected harmful factors
If a cover performs linear movement and rotational movement to remove the step, then the step is removed and foreign substance interference is eliminated, but the unit cost of the moving object increases due to requiring multiple devices
Solution Approach 1:
The patent merges linear movement capability and rotational movement capability into a single cover component. By integrating both movement types into one part rather than using separate devices, the manufacturing complexity and unit cost are reduced while still eliminating the step that causes foreign substance interference
Solution Approach 2:
The cover is designed as a universal component performing multiple functions: linear displacement to bridge the step and rotational movement to open/close. This multi-functionality reduces the total number of parts requiring manufacturing, assembly, and maintenance, thereby lowering unit cost while solving the foreign substance interference problem
3Ease of operation
If a cover is provided to open or close the opening through rotation about an axis, then the cover can close the opening, but a step is formed between the cover and body causing foreign substances to interfere with operation
Solution Approach 1:
The cover transitions from a static rotational component to a dynamic component capable of both linear and rotational movement. By making the cover dynamically adjustable in position (linear movement) and orientation (rotational movement), it can bridge the step gap while maintaining sealing contact, thus preserving ease of operation while eliminating foreign substance interference

AI summary
A moving object cabin includes a body having an opening open in a predetermined first direction and defining an internal space communicating with the opening, a cover provided to open or close the opening, and a cover moving part disposed in the internal space of the body and coupled to the cover to move the cover.
