Sliding Door Synchronization via Connecting Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door units in desktop computer chassis often experience tilting and sticking issues when pushed from a point far from their center, leading to uneven sliding motion due to separate track mechanisms on both sides, which disrupts smooth operation.
Innovation Solution
A sliding door unit with a base, a sliding component, and dual movement mechanism groups at opposite ends that move synchronously to ensure even sliding, utilizing a connecting rod or other mechanisms like belt drive or rack and pinion to maintain pace and prevent tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate track mechanisms are set on both sides of the sliding door, then the structure is simpler and easier to manufacture, but the sliding door tilts and gets stuck when pushed from a point far from its center
Solution Approach 1:
The patent merges the two separate track mechanisms into a unified structure by introducing a connecting rod that links the first and second movement mechanism groups. This connecting rod ensures that both sides of the sliding door move synchronously, preventing tilting and sticking while maintaining manufacturing simplicity through modular components.
Solution Approach 2:
The connecting rod acts as an intermediary element between the two separate track mechanisms. It mediates the motion between the first and second movement mechanism groups, ensuring synchronized movement and preventing the sliding door from tilting or getting stuck when pushed from off-center positions.
2Device complexity
If separate track mechanisms are set on both sides of the sliding door, then the device complexity is reduced, but the sliding motion becomes uneven and the door fails to slide smoothly
Solution Approach 1:
The patent combines the two independent track mechanisms into a coordinated system through the connecting rod. This merger maintains relatively low device complexity while ensuring that both sides of the sliding door move evenly and smoothly, greatly improving ease of operation.
Solution Approach 2:
The connecting rod serves as an intermediary that coordinates the motion between the two movement mechanism groups. It ensures synchronized movement without adding significant complexity, allowing the sliding door to move smoothly and evenly across its entire range of motion.
3Adaptability or versatility
If the sliding door is pushed from a point far from its center, then the user can apply force at any position, but the pushing force is received on one side only, causing tilting and sticking
Solution Approach 1:
The connecting rod acts as a mediator that distributes the pushing force from either side of the sliding door to both movement mechanism groups. When force is applied at any position, the connecting rod ensures that both the first and second movement mechanism groups move synchronously, preventing tilting and sticking while maintaining adaptability to various pushing positions.
Solution Approach 2:
The connecting rod pre-establishes a mechanical linkage between the two movement mechanism groups before any pushing force is applied. This preliminary connection ensures that regardless of where the force is applied, both sides of the sliding door are prepared to move synchronously, preventing tilting and sticking from the outset.

AI summary
Embodiments of the present disclosure provide a sliding door unit and an electronic device thereof. The sliding door unit includes a sliding door, setting on a base through a sliding component, and configured to slide relative to the base when receiving an external force; a first movement mechanism group placed at a first end of the sliding door; and a second movement mechanism group placed at a second end of the sliding door, and the first and second ends being two opposite ends. The first movement mechanism group and the second movement mechanism group move at a matching pace relative to the sliding door on the base when the sliding door is moved by the external force.
