Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wind energy is captured to power the advertising panel, then energy autonomy is improved, but device complexity increases due to additional energy conversion components
Solution Approach 1:
The advertising panel structure serves multiple functions: it displays advertisements, captures wind energy through pallet rotation, and converts mechanical motion to electrical energy. This multi-functionality reduces the need for separate structures, partially offsetting the added complexity of energy conversion components.
Solution Approach 2:
The system generates its own electrical energy through wind-driven pallet rotation and alternator conversion, making it self-sufficient. The generated power operates the display panels and lighting, eliminating the need for external power sources or battery replacements.
2Productivity
If pallets rotate at angles up to ±45° to attract attention, then advertising effectiveness is improved, but mechanical stress on the structure increases
Solution Approach 1:
The pallets are designed to rotate dynamically between fixed positions and ±45° angled positions. This dynamic capability allows the system to adapt its configuration for maximum visibility while managing mechanical stresses through controlled motion ranges and return to neutral positions.
Solution Approach 2:
The pallets perform periodic rotation between fixed and angled positions to attract attention, then return to fixed positions. This periodic action allows the structure to experience controlled mechanical stress only during brief intervals, followed by rest periods that reduce cumulative fatigue.
3Power
If motion transformation mechanisms are added to convert tilting motion to continuous rotation, then energy generation efficiency is improved, but device complexity increases
Solution Approach 1:
Motion transformation mechanisms act as intermediaries between the pallet tilting motion and the alternator. These mechanisms convert the back-and-forth tilting motion into continuous rotational motion that the alternator can efficiently convert to electrical energy, bridging the gap between the two motion types.
Solution Approach 2:
The system uses hydraulic mechanisms to transform the ±45° tilting motion of pallets into continuous rotational motion. Hydraulic motors convert the reciprocating motion into continuous rotation, driving the alternator efficiently while managing the complexity through fluid-based motion conversion.

AI summary
The system of the invention essentially consists of a rectangular advertising panel divided into two parts and pivoting about an axis located in the mid-plane thereof. Each of the parts of the panel is formed by pivoting vertical vanes, each vane comprising a portion of the advertising image that has been attached or glued thereto. The rotationally connected vanes of each part are rotated by an electric motor. The vanes of the two parts rotate in an alternating manner such that the wind can act on one or other of the parts in order to swivel same through a maximum angle of ± 45°. This swiveling movement is transformed into a continuous rotational movement. The invention comprises two shafts, one located at the top of the panel and one located at the bottom of the panel, and the continuous rotation of one of said two shafts is transmitted to a speed-increasing gear and subsequently to a low-pressure pump. The two pumps force oil from a tank located at the bottom into a hydraulic motor, which in turn drives an alternator in order to produce the electrical energy that is required to operate the two motors and to illuminate the panel if necessary, with use being made of the remaining electrical energy.
