Road Sign Enclosure for Temporary Traffic Instruction Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road signs can generate misleading sentiments by displaying permanent traffic control instructions that conflict with temporary instructions, leading to confusion among drivers.
Innovation Solution
A road sign covering system comprising a road sign structure and an enclosure structure that obscures the permanent traffic control instruction and displays a temporary traffic control instruction, forming a protection space to prevent confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permanent road sign displays permanent traffic control instructions, then the road sign structure provides stable and reliable traffic guidance, but it may generate misleading sentiments when temporary traffic control instructions are needed
Solution Approach 1:
The enclosure structure is nested within or attached to the road sign structure, forming a protective space that contains the permanent sign while allowing it to be obscured when needed. This nested configuration enables the permanent sign to maintain its structural integrity and permanent instruction while being temporarily covered by the enclosure during temporary traffic control situations.
Solution Approach 2:
The enclosure structure acts as an intermediary between the permanent road sign and the environment. It mediates the display of traffic control instructions by selectively obscuring the permanent sign when temporary instructions are active, thereby preventing misleading information from reaching drivers while preserving the permanent sign's function when appropriate.
2Stability of the object's composition
If the permanent traffic control instruction is always visible, then drivers receive consistent information, but confusion arises when temporary instructions conflict with permanent instructions
Solution Approach 1:
The enclosure structure is prepared in advance to counteract the potential harmful effect of conflicting traffic instructions. By having the enclosure ready to be deployed over the permanent sign, the system prevents the harmful confusion from occurring in the first place, rather than attempting to resolve confusion after it arises.
Solution Approach 2:
The enclosure structure extracts or removes the permanent traffic control instruction from view when temporary instructions are active. This extraction prevents the permanent instruction from being perceived by drivers during temporary control situations, thereby eliminating the source of confusion while maintaining the permanent sign for when it is appropriate.
3Loss of information
If the road sign structure is modified to display both permanent and temporary instructions simultaneously, then all information is available, but the sign becomes complex and difficult to understand
Solution Approach 1:
The traffic control information display is segmented into two separate functional components: the permanent road sign structure with permanent instructions, and the removable enclosure structure with temporary instructions. This segmentation allows each component to serve its specific purpose independently, avoiding the complexity of integrating both types of information into a single confusing display.
Solution Approach 2:
The system transitions from a static permanent sign to a dynamic configuration where the enclosure can be added or removed based on traffic control needs. This dynamic capability allows the system to adapt its information display - showing only permanent instructions when appropriate, only temporary instructions when the enclosure is deployed, or neither - thereby maintaining simplicity while providing complete information when needed.

AI summary
The road sign covering system is a traffic control device. The road sign covering system incorporates a road sign structure and an enclosure structure. The road sign covering system is a temporary device used to reconfigure the sentiment generated by the road sign structure by changing the image displayed from the road sign structure. The road sign covering system forms a protection space that prevents the original image on the road sign structure from generating misleading sentiments regarding the temporary traffic control instruction currently in effect. The road sign structure is the structure of the road sign covering system that presents the permanent traffic control instruction intended to be displayed at a location. The enclosure structure is the structure that: a) obscures the permanent traffic control instruction displayed by the road sign structure; and, b) displays the temporary traffic control instruction currently in effect.
