Projection Device for Construction Plan Object Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In construction projects, transferring objects from a construction plan to a construction site is time-consuming and prone to errors, and conventional plans do not display the chronological sequence of object creation.
Innovation Solution
A method and device that select and load a construction plan into a control device, determine a current display field on a projection device, align projection parameters with the plan, and project objects and data onto the site boundary surface, allowing for precise alignment and chronological sequencing of construction tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If objects are transferred from construction plan to construction site manually, then construction work can be carried out, but transfer errors occur and time is consumed
Solution Approach 1:
The invention projects construction plan objects directly onto the construction site boundary surfaces using a projection device. This creates a visual copy of the plan objects at their actual locations, eliminating manual transfer and ensuring accuracy while reducing time consumption.
Solution Approach 2:
A control device acts as an intermediary between the construction plan and the projection device. It automatically determines which objects are located in the current display field and transmits the corresponding projection data, eliminating manual selection and reducing errors.
2Loss of information
If all objects from construction plan are projected onto boundary surface, then complete information is displayed, but display complexity and information overload increase
Solution Approach 1:
The projection device displays only the objects and object data that are located in the current display field at the operator's current position and orientation. This localized display approach provides complete relevant information without overwhelming the operator with unnecessary data from other areas.
Solution Approach 2:
The system dynamically adjusts the displayed objects based on the operator's current position and orientation. As the operator moves and changes orientation, the set of projected objects automatically updates to reflect only those within the current display field, making the display adaptive and context-relevant.
3Loss of information
If conventional construction plan is used, then chronological sequence information is lost, but if all objects are displayed without sequencing, then construction workflow coordination becomes difficult
Solution Approach 1:
The projection device not only projects the visual representation of construction objects but also projects associated object data including chronological sequence information directly onto the boundary surfaces. This preserves and displays the temporal relationships between construction tasks at their spatial locations.
