Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection systems are inefficient when dealing with multiple work spots, leading to prolonged construction periods and increased worker burdens due to the need for manual adjustment of projection angles.
Innovation Solution
A projection system with a driver that automatically adjusts the orientation of the projection device to include multiple work spots within its projection angle, allowing sequential projection onto work spots outside the initial projection range, thereby reducing the need for manual intervention and optimizing workflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single projection device is used to project onto multiple work spots, then device complexity is reduced, but the projection angle cannot cover all work spots simultaneously
Solution Approach 1:
The projection device is made dynamically adjustable through a driver mechanism that enables automatic rotation and tilting. This allows the device to adapt its projection angle dynamically to cover different work spots sequentially, resolving the contradiction between using a single device and maintaining versatile coverage.
Solution Approach 2:
The single projection device is designed with multi-functional capability to serve multiple work spots by automatically adjusting its orientation. The driver enables the device to perform the function of multiple fixed projection devices by rotating and tilting to different positions, achieving universal coverage with one device.
2Adaptability or versatility
If the projection device manually adjusts orientation for each work spot, then projection coverage is improved, but worker burden increases
Solution Approach 1:
The projection device performs self-adjustment of its orientation automatically through the driver mechanism. The device serves itself by rotating and tilting to the correct angles without requiring manual intervention from workers, thus maintaining versatile projection coverage while eliminating operational burden.
Solution Approach 2:
The manual mechanical adjustment system is replaced with an automated driver system that uses motorized control to adjust the projection device's orientation. This substitution eliminates the need for manual physical adjustment while maintaining the ability to cover multiple work spots.
3Manufacturing precision
If workers manually reposition the projection device between work spots, then projection accuracy is maintained, but construction period is prolonged
Solution Approach 1:
The driver mechanism pre-calculates and automatically executes the optimal rotation and tilting angles to position the projection device for each work spot. This preliminary automated positioning maintains projection accuracy while eliminating the time-consuming manual repositioning process, thus shortening the construction period.
Solution Approach 2:
The manual mechanical repositioning process is replaced with an automated motorized driver system that rapidly and accurately repositions the projection device between work spots. This substitution maintains precision while dramatically reducing the time required for repositioning, thereby improving productivity.
4Productivity
If multiple projection devices are deployed for simultaneous projection, then productivity increases, but device complexity and cost increase
Solution Approach 1:
The single projection device uses dynamic automatic rotation and tilting capabilities to sequentially project onto multiple work spots without manual intervention. This dynamic operation enables the device to effectively perform the work of multiple static devices, maintaining productivity while reducing device complexity and cost.
Solution Approach 2:
The projection device is designed with universal multi-functionality to serve multiple work spots that would traditionally require separate dedicated devices. By automatically adjusting its orientation through the driver, one device performs the combined function of multiple devices, reducing complexity while maintaining parallel projection productivity.

AI summary
A projection system includes a projection device that projects drawings individually onto a plurality of work spots in a work site. The projection device includes a driver that changes an orientation of the projection device. When drawings are individually projected onto a first work spot and a second work spot in a stated sequence, and the second work spot is outside a projection angle that is projectable by the projection device, the driver changes the orientation of the projection device to include the second work spot within the projection angle after work at the first work spot is finished. The first work spot and the second work spot are included in the plurality of work spots.
