Wireless Doorsill Plate Power Management and Dynamic Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless doorsill plates face issues with power stability due to high electric power requirements when activating the wireless, display, and light-emitting modules simultaneously, often resulting in abnormal operation or failure, and they lack the ability to change displayed information after purchase, leading to increased manufacturing costs for different logos.
Innovation Solution
A wireless doorsill plate design incorporating a baseplate with a circuit board, a battery module, a radio frequency module, a display module, and an energy-saving module, where the energy-saving module reduces power consumption by controlling the backlight unit based on activation signals, allowing for stable power output and enabling changeable display information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If button cell batteries are used to reduce the thickness of the doorsill plate, then the size of the doorsill plate is reduced, but the electric power required when activating the wireless module, display module and light-emitting module simultaneously is far greater than the load that the button cell batteries can withstand
Solution Approach 1:
The patent implements periodic action by controlling the backlight unit to operate only during specific time periods when activation signals are received, rather than continuously. The energy-saving module turns on the backlight unit based on received wireless signals, creating a periodic on-off pattern that reduces average power consumption to levels suitable for button cell batteries while maintaining visibility when needed.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the operational parameters of the backlight unit based on received signals. The energy-saving module modifies the power consumption parameter by controlling the backlight unit's activation state, changing it from a constant high-power state to a variable state that adapts to communication needs, thereby reducing the overall power load on the button cell battery.
2Ease of manufacture
If the texts or graphics displayed on the doorsill plate are printed or hollowed out by laser cutting at the factory, then the manufacturing process is simple, but the text or graphics cannot be modified after purchase and different brands require different production molds
Solution Approach 1:
The patent implements copying by replacing physical printed or laser-cut text with electronic display elements that can show text and graphics. The display module can reproduce various characters, logos, and information through electronic means, allowing the same physical doorsill plate to display different content for different car brands and users without requiring different manufacturing molds.
Solution Approach 2:
The patent applies dynamics by transforming the static, fixed display content into dynamic, changeable information. The display module can update and modify displayed text and graphics in real-time based on received signals, enabling the same doorsill plate structure to adapt to different brands and user preferences without physical reconfiguration.
