Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional sandwich boards use manual message writing or securing, then the device structure remains simple, but the advertising efficiency and message update speed deteriorate
Solution Approach 1:
The patent replaces the manual mechanical system of writing or securing physical messages with an electronic display system. The sandwich board incorporates an electronic display unit that can be controlled remotely or automatically, eliminating the need for manual message changes while significantly improving advertising efficiency and message update speed.
Solution Approach 2:
The patent implements self-service functionality through automated message updating capabilities. The electronic display can be programmed to change messages automatically based on pre-set schedules or triggers, eliminating the need for continuous manual intervention and allowing the advertising device to update its content autonomously.
2Ease of operation
If conventional sandwich boards lack integrated visual elements, then the device remains simple, but the ability to capture attention deteriorates
Solution Approach 1:
The patent merges the sandwich board structure with an electronic display unit and visual attention-grabbing elements into a single integrated device. This combination allows the advertising board to not only display messages but also actively capture attention through dynamic visual effects, improving ease of operation regarding attention capture.
Solution Approach 2:
The patent incorporates visual attention-grabbing elements that utilize color changes and dynamic visual effects. The electronic display can change colors, display animated content, or create visual patterns that actively attract pedestrian attention, transforming the static sandwich board into an engaging advertising medium.
3Loss of time
If sandwich boards require manual message changes, then the device structure remains simple, but the message update time increases
Solution Approach 1:
The patent replaces the time-consuming manual message change process with an electronic display system that can update messages instantaneously or according to pre-programmed schedules. This substitution dramatically reduces message update time while the electronic control system manages the increased device complexity.
Solution Approach 2:
The patent implements preliminary action by pre-programming multiple messages and update schedules in advance. The electronic display system is configured ahead of time with a sequence of messages and timing parameters, allowing automatic message rotation and updates without requiring real-time manual intervention, thus minimizing message update time.
