Sliding Door Guide Rail Mounting with Segmented Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide rail mounting systems for sliding doors suffer from play in the longitudinal direction, limiting precise adjustment of end positions and having limited holding forces, making it difficult to achieve stable fixation and precise positioning.
Innovation Solution
A guide device with a guide rail that includes mounting parts fixed in both longitudinal and perpendicular directions, using holders with locking elements that allow for secure positioning and flexible design, enabling precise positioning of sliding doors by neglecting length and screwing tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide rail is fixed using conventional locking mechanisms, then the guide rail can be secured to the cabinet, but the guide rail has play in the longitudinal direction and limited holding forces
Solution Approach 1:
The guide rail system is segmented into multiple independent holders distributed along the guide rail length. Each holder provides localized fixation with a locking element, dividing the fixation function into discrete units that collectively achieve stable positioning without longitudinal play while maintaining precision.
Solution Approach 2:
The locking element design changes the fixation parameter from loose fitting to interference fitting with clamping force. The locking element engages with the guide rail and holder body to create a rigid connection that eliminates longitudinal play, transforming the connection state from movable to fixed.
2Strength
If multiple holders are used to secure the guide rail, then the holding forces increase, but the assembly process becomes more complex
Solution Approach 1:
Each holder is designed as a self-contained unit with integrated locking mechanism that automatically engages and secures the guide rail. The locking element can be actuated by a pivotable lever, allowing the holder to self-secure the guide rail without requiring additional fastening operations or complex assembly procedures.
Solution Approach 2:
The holders are designed with universal applicability to work with standard guide rail profiles. Each holder performs multiple functions: mechanical support, lateral positioning, and longitudinal fixation through the locking element, eliminating the need for different types of holders or additional components.
3Stability of the object's composition
If the guide rail is secured at multiple positions perpendicular to the longitudinal direction, then the guide rail is stable, but the assembly time increases
Solution Approach 1:
The holders are pre-positioned at optimal locations along the guide rail before assembly, and the guide rail is designed with corresponding engagement features. The locking elements are pre-configured in the holders, allowing for rapid engagement without requiring complex alignment or adjustment during the assembly process.
Solution Approach 2:
The complex mechanical alignment and fastening operations are replaced by simple insertion and locking lever actuation. The locking element mechanism substitutes for traditional multi-step fastening procedures, reducing assembly time while maintaining stability through multiple perpendicular fixation points.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides stable fixation of the guide rail, allowing for precise positioning of sliding doors and flexible design options, while ensuring the guide rail is securely attached to the floor or top shelf, preventing lifting or horizontal movement.
Implementation Method 1
The locking element preferably has a resilient section formed integrally thereon or interact with a separate spring element so that the clamping forces do not exceed a certain value and/or to compensate for tolerances.
