Accommodating unit of an insertion connection and insertion connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug-in connections for positioning drawers on slides lack flexibility for height adjustment and tolerance compensation, leading to noise and instability due to rigid attachment systems.
Innovation Solution
A receiving unit with a guide aligned transversely to the drawer's movement direction, featuring energy accumulators that allow receiving bodies to move and accommodate a plug-in unit steplessly, and a separate housing part for additional alignment and tolerance compensation, along with a height adjustment unit for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid attachment system with fixed positioning hooks is used, then the drawer is securely fixed to the runner, but height adjustment and tolerance compensation are limited or impossible
Solution Approach 1:
The receiving bodies are designed to be movable within the housing along a guide, transitioning from an initial position to an inserted position. This dynamic mechanism allows the system to adapt to different heights and tolerances while maintaining secure fixation when engaged.
Solution Approach 2:
The energy accumulator (spring element) enables the receiving bodies to change their position parameter elastically. The spring allows the receiving bodies to move against its force, providing continuous adjustment capability for height and tolerance compensation.
2Device complexity
If a rigid attachment system with fixed positioning hooks is used, then the drawer structure is simple, but manufacturing tolerances and alignment issues cannot be compensated
Solution Approach 1:
The spring element enables the receiving bodies to change their position parameter elastically, absorbing manufacturing tolerances in both the drawer and runner while maintaining proper alignment and engagement.
3Device complexity
If the drawer rests loosely on the runner without proper positioning, then the attachment system is simple, but the drawer produces unwanted noise and lacks stability
Solution Approach 1:
The dynamic positioning mechanism ensures the drawer is properly supported and engaged with the runner, eliminating loose movement and the associated noise while maintaining operational smoothness.
4Stability of the object's composition
If receiving bodies are enclosed rigidly in a housing, then the structure is stable, but the plug-in unit cannot penetrate steplessly for continuous adjustment
Solution Approach 1:
The guide allows receiving bodies to move dynamically within the housing from an initial position to an inserted position, enabling continuous adjustment while the housing provides stable structural support.
Solution Approach 2:
The spring element enables continuous position adjustment of the receiving bodies by allowing elastic movement against the spring force, providing stepless penetration capability for the plug-in unit.
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
Enables flexible and noise-free operation by allowing stepless penetration of the plug-in unit and compensating for manufacturing tolerances, ensuring stable and quiet drawer movement.
Implementation Method 1
the energy accumulator is designed as a U-shaped or L-shaped spring element that compresses the receiving bodies or as an annular spring element that compresses and encloses the receiving bodies
