Mobile Device Projection Module for Targeted Ad Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile advertisements lack targeted delivery based on user characteristics and location, often being intrusive and ineffective due to small screen space, leading to low acceptance and poor communication of advertising content.
Innovation Solution
A mobile device equipped with a projection module, camera module group, and control circuit board that acquires and adjusts advertisement content projection based on environment and viewer data, allowing for flexible and targeted advertising by projecting content onto external surfaces, including people and objects, using a DLP miniature projection module with LED light source and GPS for location-based content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If advertisements are embedded in mobile terminal screens, then mobile advertisements can be displayed, but the screen space is limited and advertisement contents are too small for users to notice
Solution Approach 1:
The patent transitions from two-dimensional screen display to three-dimensional projection display. The projection module projects advertisement contents onto external surfaces (walls, posters, people's clothes), expanding the display area from the limited mobile screen to large external surfaces, thereby solving the contradiction between display area and device portability.
Solution Approach 2:
The patent introduces a projection module as an intermediary between the mobile device and the display surface. This intermediary component converts the digital advertisement content into projected light images that can be displayed on external surfaces, enabling large-area advertisement display without requiring a large physical device.
2Productivity
If spam messages and advertisements are sent to mobile phones, then advertisement delivery is achieved, but user data cannot be accurately controlled and target groups cannot be established
Solution Approach 1:
The patent employs camera modules to capture real-time images of the surrounding environment and user reactions to projected advertisements. This feedback mechanism allows the system to identify target audiences, analyze their characteristics, and adjust advertisement content accordingly, thereby establishing clear target groups and improving advertisement delivery efficiency while preserving user data relevance.
Solution Approach 2:
The patent replaces the traditional text-based spam message delivery system with a visual projection system enhanced by image recognition technology. The camera modules capture visual information about users and environment, substituting mechanical data collection methods with optical sensing, enabling accurate identification of target groups without losing user characteristic data.
3Area of stationary object
If advertisements are projected onto external surfaces, then advertisement display area is expanded and user engagement is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functional modules (projection module, camera module group, GPS module, main unit fixing device) into a single mobile device structure. By merging these components into one unified system, the patent achieves large-area advertisement projection capability while managing device complexity through integrated design rather than separate components.
Solution Approach 2:
The mobile device is designed with multi-functionality, serving both as a conventional mobile device and as an advertisement projection system. The projection module, camera modules, and GPS functionality are integrated into the existing mobile device framework, allowing the device to perform multiple functions without proportionally increasing complexity.

AI summary
A mobile device and method for advertisement projecting. The mobile device includes: a main unit with a control circuit board; a projection module for projecting advertisement contents; a projection display window for completely displaying projection contents from the projection module, a camera module group for acquiring projection environment information in front of and behind the projection display window, and a main unit fixing device for fixing the mobile device for advertisement projecting on a mobile body. The main unit is configured to push corresponding advertisement contents which is projected by the projection module according to the projection environment information.
