Wall, particularly a side wall, for a drawer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing frame designs for drawers, particularly side frames, face challenges in simplifying the assembly and accessibility of front panels, especially when it comes to the connecting fittings and locking devices, which can be complex and difficult to operate manually.
Innovation Solution
The design enhances the mobility of the outer shell relative to the inner shell, allowing for easier access to the locking device by incorporating sliding guides and a securing element like a screw or resilient pressure piece, which ensures a uniform contact and prevents unintentional displacement, thus simplifying the assembly and operation of the front panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the locking device is arranged between the inner shell and outer shell, then the connecting fitting becomes more compact, but the accessibility of the locking device deteriorates
Solution Approach 1:
The outer shell is made displaceable relative to the inner shell through sliding guides, allowing the outer shell to move dynamically during assembly and disassembly operations. This dynamic configuration enables the locking device to be accessed by temporarily displacing the outer shell, resolving the contradiction between compact arrangement and accessibility.
2Ease of operation
If the outer shell is made displaceable relative to the inner shell, then the accessibility to functional elements is improved, but the stability of the frame structure deteriorates
Solution Approach 1:
The frame structure transitions from a static to a dynamic configuration, where the outer shell can be displaced relative to the inner shell during operations but returns to a stable locked position. The sliding guides enable controlled movement while maintaining structural integrity.
Solution Approach 2:
Sliding guides act as intermediary elements between the outer and inner shells, enabling relative displacement while maintaining structural stability. The guides provide a controlled path for movement and prevent unstable or uncontrolled displacement.
3Ease of manufacture
If sliding guides are incorporated to enable outer shell displacement, then the ease of assembly is improved, but the device complexity increases
Solution Approach 1:
The sliding guides implement a simple dynamic mechanism that enables the outer shell to move relative to the inner shell along a defined path. This dynamic feature simplifies assembly operations without requiring complex mechanisms, achieving ease of assembly with minimal added complexity.
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
This design improves the accessibility and ease of handling the locking device during assembly or dismantling, ensuring a secure and uniform joint appearance while preventing accidental movement of the outer shell relative to the inner shell, thus enhancing the overall assembly process and visual appeal.
Implementation Method 1
the at least one energy storage device advantageously produces a force in the area of the connection between the inner and outer shells, which presses the inner and outer shells together
Implementation Method 2
the locking element is a screw and/or a spring-loaded pressure piece comprising at least one spring, which is a helical spring
