Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional printed advertising papers are used on handles, then advertising information can be displayed, but it causes waste of ink and paper and environmental pollution
Solution Approach 1:
The patent replaces the mechanical system of printed advertising papers with electronic display devices (e-paper or LED screens) mounted on handles. This substitution eliminates the need for physical printing and paper usage, thereby reducing ink and paper waste while maintaining advertising information display functionality.
Solution Approach 2:
The patent changes the physical state of advertising information from static printed material to dynamic electronic display. The display devices can be updated remotely and repeatedly without consuming additional physical materials, transforming the advertising medium from consumable paper to reusable electronic components.
2Adaptability or versatility
If manual replacement of advertising papers is performed, then advertising content can be updated, but it is time-consuming for personnel
Solution Approach 1:
The patent implements a self-service advertising update system where the electronic display devices can be remotely controlled and updated without manual intervention. The central control system can push advertising content to multiple handles simultaneously, eliminating the need for personnel to physically replace advertising materials and significantly reducing update time.
Solution Approach 2:
The patent enables preliminary preparation of advertising content on the electronic displays, which can be pre-loaded and automatically switched between different advertisements. This allows for seamless transitions between advertising content without requiring manual removal and installation of physical papers.
3Reliability
If a fixed advertising structure is used on handles, then advertising can be displayed, but it cannot match various handle types
Solution Approach 1:
The patent designs the advertising display device with universal mounting capabilities that can accommodate different handle types, shapes, and sizes. The device incorporates adjustable mounting brackets and flexible fixing mechanisms that can be adapted to various handle configurations, enabling a single design to serve multiple applications across different public transportation vehicles.
Solution Approach 2:
The patent divides the advertising display device into modular components, including a separate mounting mechanism and display unit. This segmentation allows the mounting portion to be customized or adjusted for different handle types while keeping the display functionality standardized, thereby achieving both stability and adaptability.

AI summary
A display device installed on the handle of a public transportation vehicle displays advertising information. The display device includes a body and two displays. The body includes a housing. The housing has a first surface, a second surface opposite the first surface, a third surface, and an opening. The housing is provided with a fixed hole penetrating through the first surface and the second surface. The housing is provided with a fixing component therein. The housing is provided with two electronic component-accommodating portions therein. The electronic component-accommodating portions are respectively arranged at two sides of the fixed hole. The third surface and the opening are perpendicular to the first surface and the second surface. The display device can reduce waste of ink and paper due to using advertising papers to advertise.
