Drawer, drawer construction and method for manufacturing a drawer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing drawers often require expensive machinery for milling locking profiles on all corners, which is not economically viable for furniture manufacturers who need to produce their own front panels, and result in inefficient production and assembly processes.
Innovation Solution
The use of locking profiles only for connecting the rear wall to the sidewalls, with separate connection means, such as dowels or pins, for connecting the front wall to the sidewalls, allowing for a plug-in principle and eliminating the need for intricate profiles on the front wall, thereby simplifying the assembly process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If locking profiles are applied on all corners of a drawer, then the construction stability is improved, but the manufacturing cost and complexity increase due to requiring expensive milling machinery
Solution Approach 1:
The drawer is divided into two zones: the rear wall uses locking profiles for stable connections, while the front wall uses simpler connection means. This segmentation allows each part to be optimized independently, reducing overall manufacturing complexity while maintaining necessary stability where required.
Solution Approach 2:
Different connection methods are applied to different locations of the drawer. The rear wall receives the more complex locking profile connection for structural stability, while the front wall uses simpler connection means, creating local quality differentiation that optimizes both stability and manufacturability.
2Strength
If locking profiles are used on the front wall, then the connection strength is improved, but the ease of operation deteriorates as furniture manufacturers need to acquire expensive milling machinery
Solution Approach 1:
The connection system is segmented into two types: locking profiles for the rear wall providing strong connections, and simpler connection means for the front wall that can be manufactured with basic equipment. This allows furniture manufacturers to produce front panels without acquiring expensive milling machinery.
Solution Approach 2:
The front wall connection uses simpler, cheaper connection means that can be produced with basic manufacturing equipment, replacing the need for expensive locking profile machinery at the furniture manufacturer's facility. The rear wall retains the more robust locking profiles for structural integrity.
3Reliability
If intricate locking profiles are provided on the front wall, then the connection reliability is improved, but the device complexity increases requiring specialized machinery
Solution Approach 1:
The drawer connection system is segmented into two parts: the rear wall uses intricate locking profiles for reliable connections, while the front wall uses simpler connection means. This segmentation reduces overall device complexity while maintaining reliability where it is most needed for structural integrity.
