Mobile Projection Device on Road Vehicle Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projection mapping installations are costly and logistically challenging due to the need for unique scaffolding and extensive manpower, with each project requiring separate setup and administrative authorization, limiting flexibility and increasing expenses.
Innovation Solution
A mobile projection device mounted on a road vehicle with wheels, equipped with one or more light projector units that can be easily transported and set up, reducing the need for extensive scaffolding and manpower, and allowing for certification and authorization processes to be handled once for a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional scaffolding and multiple projectors are used for each project, then projection mapping quality can be achieved, but installation cost and time increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-assembling the projection device on a road vehicle chassis before deployment. The structure, projectors, and control systems are integrated in advance, eliminating the need for on-site scaffolding construction and projector installation. This pre-integration maintains projection quality while dramatically reducing installation time and manual labor requirements.
Solution Approach 2:
The patent uses the road vehicle chassis as a portable, pre-fabricated platform that copies the functional capabilities of traditional fixed scaffolding. Instead of building custom scaffolding for each project, the vehicle chassis serves as a reusable, transportable copy that provides the same structural support and projector mounting capabilities, reducing both time and cost.
2Adaptability or versatility
If custom scaffolding is built for each project, then specific project requirements are met, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing the road vehicle chassis to serve multiple functions: it provides structural support, houses projection equipment, enables mobility, and offers power supply. This multi-functional platform replaces the need for separate scaffolding, equipment racks, and power distribution systems, reducing overall device complexity while maintaining adaptability to different project requirements through software control and projector configuration.
3Power
If extensive scaffolding and equipment are deployed, then projection capabilities are achieved, but manpower requirements and operational costs increase
Solution Approach 1:
The patent merges multiple previously separate components into a single integrated mobile device: the road vehicle chassis combines structural support, equipment mounting, power supply, and mobility functions. The projection equipment is consolidated on this single platform, reducing the number of separate scaffolding structures and equipment handlers needed. This integration maintains high light power output while significantly reducing manpower requirements for setup and operation.
4Manufacturing precision
If traditional installation methods are used, then project specifications are met, but administrative authorization processes become more difficult and time-consuming
Solution Approach 1:
The patent applies dynamics by making the projection system mobile rather than fixed. The road vehicle chassis can be quickly relocated and repositioned, allowing the device to adapt to different locations without requiring permanent infrastructure installation. This mobility simplifies administrative authorization processes, as the device does not require complex permits for permanent structure installation while still meeting project specifications through flexible deployment.
