Drawer for a storage system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated stock control systems face challenges in cost-effectively monitoring drawer movement and reconfiguring compartments to accommodate items of different shapes and sizes, as they require additional components and are cumbersome to modify.
Innovation Solution
The introduction of a drawer insert with sprung legs and tapered ends that fit into guiding slots, allowing for adjustable compartment sizes without compromising rigidity or security, and the use of a series of projections and gaps to replace the raster strip for movement detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a raster strip is mounted onto each drawer by means of screws, then drawer movement can be monitored, but the system cost and complexity increase
Solution Approach 1:
The patent combines the drawer body and the measurement markings (projections and gaps) into a single integrated component. The projections are directly formed on the drawer body at predetermined intervals, eliminating the need for separate raster strips and their mounting hardware. This merging reduces the number of components while maintaining the functionality of monitoring drawer movement, position, speed, and direction.
2Strength
If compartment walls are moulded into the drawer and fixed, then drawer structure is rigid, but compartment sizes cannot be changed
Solution Approach 1:
The patent introduces removable inserts that can be placed within the drawer to create compartments. These inserts are separate from the drawer body and can be added, removed, or repositioned according to storage needs. The drawer body itself remains rigid and structurally sound, while the compartment configuration becomes flexible and adaptable to different article sizes and shapes.
3Adaptability or versatility
If removable compartment walls are used, then compartment reconfiguration is possible, but the structure becomes flimsy and can be easily tampered with
Solution Approach 1:
The inserts serve multiple functions: they create compartment divisions, provide structural support for stored articles, and can be securely positioned within the drawer. The inserts are designed to work with the rigid drawer body, combining the flexibility of reconfigurable compartments with the security and stability of a solid drawer structure. The inserts can be easily installed and removed by users without compromising drawer integrity.
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 solution provides a cost-effective and flexible way to monitor drawer movement and reconfigure compartments, reducing system complexity and costs while ensuring accurate position detection and secure operation.
Implementation Method 1
the legs of the insert are sprung such that they bend inwards to aid insertion of the insert into guiding slots formed in the body of the drawer

AI summary
A drawer (100) comprising at least one receptacle (103) open at the top of the drawer; a drawer information means extending in a depth direction of the drawer, wherein the drawer information means comprises a series of projections (108) moulded into the drawer. The drawer also comprises guiding slots (104) for holding an insert (400) having a plate (401); and a pair of legs (404a, 404b) formed in the body of the plate and extending longitudinally upwards along the sides of the plate.
