Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer dividers are complex, difficult to install, and lack stability, making them inconvenient and impractical for effective space organization in storage furniture.
Innovation Solution
A retractable drawer partition plate with a simple structure, comprising a fixed plate, a toothed plate, and a switch assembly that allows for adjustable extension and locking, ensuring secure and stable installation by using a locking block, movable block, pull rod, and elastic member for pre-tightening pressure against the drawer wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a telescopic partition board with multiple parts is used to achieve adjustable extension, then the adaptability of the drawer space is improved, but the device complexity increases and installation becomes difficult
Solution Approach 1:
The partition board is divided into a fixed plate and a toothed plate that can move relative to each other. The toothed plates on both plates enable segmented adjustment of the partition board length by engaging or disengaging the teeth, providing adaptability while keeping the structure simple and easy to install.
Solution Approach 2:
The movable block with the locking block is nested within the groove of the fixed plate. The locking block can slide along the groove and engage with the toothed plate's teeth, creating a compact nested structure that achieves adjustable extension without increasing overall device complexity.
2Ease of operation
If the connecting plate is not pressed tightly against the inner wall of the drawer, then the ease of installation is improved, but the stability decreases and the partition board may tilt or roll over
Solution Approach 1:
The elastic piece is pre-compressed between the movable block and the end of the groove, generating a preliminary pushing force that automatically presses the toothed plate against the inner wall of the drawer when the locking block engages. This preliminary action ensures stability without complicating the installation process.
Solution Approach 2:
The elastic piece automatically generates the necessary pressing force against the inner wall through its elastic deformation. The system self-regulates the pressure to maintain stability, eliminating the need for additional adjustment mechanisms or complex installation steps.
3Reliability
If a locking mechanism with elastic piece is added to achieve pre-tightening pressure and stability, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking and pre-tightening functions are merged into a single integrated mechanism. The locking block simultaneously performs locking by engaging with the teeth and pre-tightening by compressing the elastic piece against the inner wall, achieving reliable fixation without adding separate complex mechanisms.
Solution Approach 2:
The elastic piece automatically generates the pre-tightening pressure through its elastic deformation when the locking block engages with the teeth. The system uses its own components to achieve both locking and pre-tightening, eliminating the need for additional actuators or complex control mechanisms.

AI summary
A retractable drawer divider includes a toothed plate telescopically arranged in a fixed plate and provided with two rows of first tooth parts arranged at intervals, wherein the toothed plate may be placed in at least a first state and a second state. A switch assembly for transitioning the toothed plate between the first and second state includes a locking block, a movable block, a pull rod and a button. The first state is an adjustable state in which the toothed plate can be freely extended and retracted, and the second state defines a fixed or locked state of the drawer divider. The drawer divider length can be adjusted easily and freely according to the size of the drawer environment, and in the locked state provides a snug fit between the divider and an inner wall of a drawer.
