Solution Overview
Problem
Existing portable display stands for safety information and equipment in high-risk environments are often makeshift, non-portable, and not reusable, leading to inefficiencies in deployment and disposal, particularly in construction sites, mining, and public events.
Innovation Solution
A portable stand designed as an open-topped box-like container with adjustable legs, hinged panels, and display chambers that can be easily transported, set up, and reused, featuring a mechanism for stacking and secure storage of safety items and information displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If display stands are made from available site materials like timber offcuts or plywood panels, then the stands can be quickly assembled on site, but they cannot be reused or transported to other locations
Solution Approach 1:
The display stand is divided into separate modular components including a base unit, display panels, and support structures that can be easily assembled and disassembled. This segmentation allows the stand to be quickly constructed from standardized parts while maintaining the capability for disassembly and relocation to different sites.
Solution Approach 2:
The display stand incorporates movable and adjustable elements such as height-adjustable legs, removable panels, and flexible support mechanisms. These dynamic features enable the stand to be easily configured, assembled, and disassembled for transport to different locations while maintaining structural integrity during use.
2Ease of manufacture
If display stands are made from available site materials, then assembly is quick, but the stands must be thrown away when the project is complete
Solution Approach 1:
The display stand is designed as a reusable system where all components can be disassembled, transported, and reassembled at different project locations. This eliminates material waste by recovering and reusing the entire stand structure across multiple projects instead of discarding single-use materials after each project completion.
Solution Approach 2:
The display stand is designed as a universal, multi-functional unit that can be deployed across various construction projects and locations. The standardized design allows the same stand to serve multiple purposes and projects, significantly reducing material waste compared to project-specific makeshift stands.
3Reliability
If safety information displays are provided at multiple locations on a large construction site, then safety coverage is improved, but the cost and complexity of providing and moving displays increases
Solution Approach 1:
The display system is segmented into multiple identical modular units that can be independently deployed at different construction site locations. Each module contains all necessary components (base, panels, supports), allowing rapid deployment across multiple locations without increasing overall system complexity, as each unit is self-contained and standardized.
Solution Approach 2:
A universal display module design allows the same standardized unit to be deployed at multiple locations throughout the construction site. This universality simplifies deployment complexity because the same configuration and assembly procedures are used at each location, making it easy to replicate safety coverage across multiple areas without proportionally increasing complexity.

AI summary
A portable stand (10) comprises a back wall (12), a base element (14), and two opposed end plates (16) between which the back wall and the base element extend, so to define an open-top box-like container. It also comprises legs (35) that can be folded up next to the base element (14); support arms (40) with a pivotal connection (42) so each support arm (40) can be moved between a closed position adjacent to the back wall (12), and a second position projecting upward from the back wall (12). In addition it comprises a front panel (20) hinged to the base element (14) so the front panel (20) can be swung between a position forming a front wall of the box-like container, and a position extending below the base element (14); and a top panel (22) hinged to the back wall (12) so it can be swung between a position forming a lid to the box-like container, and a position extending above the back wall (12). Swinging the front panel (20) and the top panel (22) in this way opens the box, and displays the exposed surfaces of the front panel (20) and of the top panel (22). There may be multiple display chambers (66) within the box-like container which are thereby displayed. The portable stand enables the display of information on the exposed surfaces, and the display of items within the display chambers (66), for example for the purpose of safety.
