Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional display is used in the hair straightening brush, then the device structure remains simple, but the display cannot achieve high-definition visual effects and animated content
Solution Approach 1:
The patent combines the display module with the existing control unit and heating element into an integrated system. The control unit processes images and controls the heating element temperature display, while the display module receives control signals to show temperature and animated content. This merging approach achieves high-definition display without significantly increasing overall device complexity.
Solution Approach 2:
The patent introduces a driver circuit as an intermediary component between the control unit and the display module. The driver circuit converts control signals into appropriate display signals, enabling the display to show high-definition images and animations. This intermediary approach allows the display module to achieve high definition while keeping the control unit architecture relatively simple.
2Adaptability or versatility
If only fixed content display is implemented, then the device structure remains simple, but user interaction and visual appeal are limited
Solution Approach 1:
The patent implements dynamic display content by enabling the display module to show animated visual effects and adjustable temperature readings. The control unit can dynamically update the display based on heating element temperature changes and user interactions, transforming the static display into a dynamic, adaptable interface that enhances user experience without requiring overly complex control logic.
Solution Approach 2:
The control unit is designed to perform multiple functions: controlling the heating element temperature, processing image data for display, and managing display content updates. This multi-functional approach allows the system to achieve versatile display content (temperature readings, animations, visual effects) while avoiding the need for separate dedicated control circuits for each function.
3Ease of operation
If high-definition display with animated effects is implemented, then user interaction is enhanced, but the device structure and control complexity increase
Solution Approach 1:
The patent merges the display control functionality into the existing main control unit rather than adding a separate control system. The control unit handles both heating element control and display content generation, reducing overall system complexity while enabling high-definition animated displays that enhance user interaction and ease of operation.

AI summary
A hair straightening brush with a thin film transistor-liquid crystal display (TFT-LCD) includes a head part and a handheld part. The head part includes a first housing, metal heat-conducting teeth, and an electric heating component. The handheld part includes a second housing, and a main control unit. The electric heating component is electrically connected to the main control unit. A display module is further disposed in the second housing, is provided with a display (TFT-LCD), and is electrically connected to the display. The display module includes a driver circuit and a signal control module, and is configured to generate timing signals for controlling row and column drivers of the display. The driver circuit is configured to: receive the timing signals for controlling the row and column drivers, convert the timing signals into row and column driver analog voltages, output the analog voltages to the display, and control liquid crystal alignment of the display.
