Solution Overview
Problem
In large drawer systems, a gap often forms where the drawer side wall meets the rear wall, which is aesthetically undesirable and worsens with height, as existing arrangements fail to ensure a gap-free connection.
Innovation Solution
The holding device is angled obliquely relative to the drawer's longitudinal extension when the rear wall is unfastened, allowing pretension to ensure the rear wall rests without gaps on the side wall, with an angle adjustment between secured and unsecured states to minimize gaps, particularly using a stop with different support areas within the side wall profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the holding device is aligned perpendicular to the longitudinal extension of the carrier body, then the drawer rear wall can be easily mounted, but a gap forms between the drawer rear wall and drawer side wall in the upper area
Solution Approach 1:
The holding device is designed with a dynamic angle adjustment mechanism that allows it to assume different angular positions depending on the state of the drawer rear wall. In the unmounted state, the holding device is angled obliquely to facilitate easy insertion. When the drawer rear wall is mounted, the holding device adjusts to a perpendicular orientation to ensure gap-free connection. This dynamic adaptability resolves the contradiction between ease of mounting and aesthetic appearance.
Solution Approach 2:
The angular parameter of the holding device relative to the longitudinal extension of the carrier body is changed based on the mounting state. The holding device transitions from an oblique angle (e.g., 85-89 degrees) in the unmounted state to a perpendicular angle (90 degrees) in the mounted state. This parameter change enables the holding device to optimize its function for both easy mounting and gap-free connection at different stages.
2Shape
If the holding device is aligned obliquely to ensure gap-free connection, then the aesthetic appearance is improved, but the mounting becomes more difficult
Solution Approach 1:
The holding device incorporates a dynamic mechanism that automatically adjusts its angular position based on the presence and state of the drawer rear wall. During mounting, the holding device assumes an oblique angle that facilitates easy insertion of the drawer rear wall. Once mounted, it transitions to a perpendicular orientation to ensure the drawer rear wall rests without gaps on the drawer side wall. This eliminates the need for manual angle adjustment and simplifies the mounting process.
Solution Approach 2:
The holding device is designed to automatically adjust its angular position in response to the mounting state of the drawer rear wall, without requiring external intervention or complex adjustment mechanisms. The device self-adjusts from an oblique mounting-friendly angle to a perpendicular gap-free angle, making the system user-friendly while maintaining aesthetic appearance.
3Reliability
If the drawer rear wall is fastened securely to the holding device, then the connection reliability is improved, but the holding device angle must be precisely controlled
Solution Approach 1:
The holding device employs a dynamic angle adjustment mechanism that automatically positions the device at the optimal perpendicular angle when the drawer rear wall is mounted. This dynamic adjustment compensates for manufacturing tolerances and ensures that the drawer rear wall rests without gaps on the drawer side wall, thereby ensuring reliable connection without requiring extremely precise manual angle control during assembly.
Solution Approach 2:
The holding device incorporates a feedback mechanism that detects the mounting state of the drawer rear wall and automatically adjusts its angular position accordingly. When the drawer rear wall is properly mounted, the feedback system ensures the holding device assumes the perpendicular orientation needed for gap-free connection, thereby maintaining connection reliability while reducing the precision requirements for manual angle control.
