Locker unit having a security feature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locker units in public spaces are vulnerable to unauthorized access due to the ease with which panels can be disassembled using common tools, compromising security.
Innovation Solution
Incorporation of an L-shaped obstructing member parallel to the side flange of each panel, which is welded to the panel's rear surface and extends along its length, preventing the hook portion of the mounting bracket from being easily bent or separated from the retaining member, thus securing the panels in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If panels are secured using common tools and simple mounting brackets, then assembly is easy and cost-effective, but security is compromised as panels can be easily pried loose
Solution Approach 1:
The obstructing member acts as an intermediary element between the panel and the mounting bracket. It prevents direct contact between prying tools and the hook portion of the mounting bracket, thereby mediating the interaction and preventing unauthorized access while maintaining the simple assembly structure
Solution Approach 2:
The obstructing member extends in a direction perpendicular to the plane of the panel, creating a three-dimensional barrier. This additional dimensional element prevents tools from reaching the mounting bracket's hook portion without adding complexity to the two-dimensional panel structure
2Reliability
If welding is used to secure the obstructing member to the panel, then security is enhanced, but manufacturing complexity increases
Solution Approach 1:
Welding is applied only at specific local positions where the obstructing member contacts the panel, rather than throughout the entire structure. This localized application enhances security at critical points while minimizing the overall manufacturing complexity and weld volume
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
The solution effectively inhibits unauthorized access to the mounting arrangement, enhancing security by making it difficult to lift and remove panels, even when assembled from common tools, thereby protecting personal belongings.
Implementation Method 1
a first leg of the L shaped plate abuts and is fastened to a rear surface of the panel

AI summary
A locker unit comprising: a cabinet body; at least one internal mounting bracket (40) provided at each lateral side of the cabinet body; at least one horizontal panel (30) mountable to each mounting bracket (40) at a vertical height so as to define two or more vertically stacked lockers, each panel (30) comprising a side flange (32) provided at each lateral edge of the panel; and a door associated with each locker, wherein each side flange has one or more apertures which are alignable with an aperture provided at the mounting bracket for receiving a retaining member (42), and wherein each panel includes an obstructing member (50) located near to each aperture of the side flange.
