Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems in goods processing devices, such as franking machines, lack precise control over the display's inclination and are prone to damage from manual adjustments, with inaccuracies in determining the angle of inclination and difficulty in maintaining the desired viewing angle for different users.
Innovation Solution
A display module with a pivotable display holder and a control unit that includes sensors for detecting the display's inclination, a motor for motorized pivoting, and additional actuation means for manual adjustment, along with a control unit that stores and retrieves the optimal tilt angle for each user, ensuring precise and damage-resistant operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is made manually adjustable, then the viewing angle can be adapted to different users, but the display is prone to damage from excessive manual pressure and coarse adjustment steps
Solution Approach 1:
The patent replaces the purely mechanical manual adjustment system with an electromechanical system. A motor (24) driven by a control unit (7) takes over the adjustment function, allowing precise control of the display inclination angle without requiring manual force from users, thereby preventing damage while maintaining adaptability.
Solution Approach 2:
The control unit (7) acts as an intermediary between the user's adjustment request and the motor-driven display holder (54). It receives the desired angle input, calculates the required motor rotation, and executes the adjustment, mediating between human intent and mechanical action to ensure precise and safe operation.
2Measurement precision
If the display inclination is determined using acceleration sensors, then the angle can be measured, but trigonometric calculations result in inaccuracies at inflection points
Solution Approach 1:
The system uses the acceleration sensor data to automatically determine the display inclination angle without requiring external calibration or manual intervention. The control unit (7) processes the sensor signals and self-adjusts the display holder (54) to the correct angle, making the system self-correcting and eliminating the need for precise manual calibration.
Solution Approach 2:
The patent employs dynamic adjustment where the display holder (54) can be continuously repositioned by the motor (24) based on real-time sensor feedback. This dynamic system allows the display to adapt its inclination angle continuously rather than being fixed at manufacturing precision points, overcoming the limitations of static calibration.
3Stability of the object's composition
If a locking mechanism is added to secure the display, then the display position can be maintained, but the adjustment process becomes more complex and may require excessive force
Solution Approach 1:
The patent replaces complex mechanical locking mechanisms with an electromechanical system. The motor (24) provides continuous positioning capability, and the control unit (7) maintains the desired angle through electronic control, eliminating the need for separate locking mechanisms and reducing overall system complexity while improving stability.

AI summary
A product processing device is equipped with an inkjet printer for producing prints on printing media, a control unit, input and output means, and a display module (5). The display module (5) comprises a display module carrier (53), a swiveling display holder (54), and a display housing, wherein a display border is arranged around a display screen and a display housing frame (52) surrounds the display border. At least one additional actuation means of the display module is provided on the display border to manually trigger motorized swiveling of the display screen. At least one sensor (521) and the control unit (7) are provided for detecting a tilt of the display screen. The detected data of the sensor (521) transmitted to the control unit correspond to a tilt angle α of a line of inclination N lying on the surface of the display screen (50) to a horizontal H extending in the y-direction.A motor (M4) is provided for the motorized swiveling of the display screen and is equipped with a gearbox that reduces the motor's revolutions and transmits them via a gearbox shaft (532) to an overload protection device. A pinion gear (534) of the overload protection device engages with a gear segment (541) of the swiveling display holder (54). Furthermore, a method is provided to determine and store data relating to the tilt of a component, such as the display.
