Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carriage and guiding rail assemblies for sliding door panels struggle with unbalancing forces not parallel to the sliding direction, leading to jamming or incorrect sliding, and lack easy connectivity for stability accessories.
Innovation Solution
A carriage and guiding rail assembly with a plate-shaped body, oscillating rolling supports, and adjustable lateral inserts that act as stability slides, allowing for easy connection of accessories and accommodating non-planar installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a clearance is provided between the carriage body and guiding rail, then the carriage can be easily assembled and installed, but the carriage moves in transverse direction under unbalancing forces and gets jammed or slides incorrectly
Solution Approach 1:
The patent applies the dynamics principle by making the lateral position of the carriage adjustable rather than fixed. The carriage body includes adjustable lateral positioning means that allow the clearance between the carriage and guiding rail to be modified after assembly. This enables the system to adapt to unbalancing forces by adjusting the lateral position, preventing transverse movement and jamming while maintaining ease of initial assembly.
Solution Approach 2:
The patent applies parameter changes by allowing the clearance parameter between the carriage body and guiding rail to be variable. The adjustable lateral positioning means enable modification of the lateral clearance parameter to optimize performance under different unbalancing forces. This transforms a fixed parameter into a variable one, resolving the contradiction between easy assembly and sliding stability.
2Reliability
If accessories are connected to the carriage to ensure stability, then door panel stability during closing and deceleration is improved, but the connection becomes difficult and complicated
Solution Approach 1:
The patent applies the merging principle by integrating the accessory connection function directly into the carriage body structure. The carriage body includes integrated connection means that allow accessories to be attached without requiring separate mounting mechanisms. This combines the carriage structure with accessory attachment capability, improving stability while avoiding additional complexity.
Solution Approach 2:
The patent applies universality by designing the carriage body with multi-functional elements that serve both structural and accessory connection purposes. The connection means are built into the carriage body, allowing the same structure to provide both mechanical support and accessory mounting functionality. This reduces overall system complexity while maintaining stability.
3Ease of manufacture
If the carriage structure is simplified for easy manufacturing, then production cost and time are reduced, but the ability to accommodate unbalancing forces and non-planar installations is limited
Solution Approach 1:
The patent applies dynamics by incorporating adjustable elements into the carriage body that allow adaptation to unbalancing forces without requiring a completely complex structure. The adjustable lateral positioning means and oscillating rolling supports enable the simplified carriage structure to adapt dynamically to varying force conditions and non-planar installations.
Solution Approach 2:
The patent applies segmentation by dividing the carriage body into modular components with distinct functions. The carriage body includes separate elements for rolling support, lateral positioning, and accessory connection. This modular segmentation allows each component to be manufactured simply while the assembled structure provides the necessary adaptability to unbalancing forces.
