Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gas strut system with adjustable torque elements is implemented, then vertical adjustment range and user customization are improved, but device complexity increases
Solution Approach 1:
The patent implements adjustable torque elements that allow the support arm to dynamically adapt to different weight loads and adjustment ranges. The torque elements can be adjusted to provide appropriate resistance throughout the vertical adjustment range, enabling the system to remain versatile across different operating conditions while managing complexity through controlled adaptability.
Solution Approach 2:
The gas strut system incorporates adjustable parameters including torque element settings and gas pressure levels. By allowing parameter adjustment, the system achieves improved vertical adjustment range and user customization without requiring multiple complete system redesigns, thus managing complexity through configurable parameters rather than structural complexity.
2Reliability
If cable management extensions and securing mechanisms are added, then cable retention effectiveness is improved, but device complexity increases
Solution Approach 1:
The cable management extension integrates multiple functions into a single component: it provides cable routing, cable retention through the loop portion, and structural support. The securing mechanism with keeper and actuator combines locking and releasing functions. This multi-functionality improves cable retention effectiveness while minimizing the increase in device complexity by consolidating functions rather than adding separate components.
Solution Approach 2:
The patent merges the cable management features directly into the support arm structure. The loop portion is integrated into the housing, and the securing mechanism is combined with the existing actuator system. This merging approach ensures reliable cable retention while avoiding the complexity of separate, standalone cable management systems.
3Stability of the object's composition
If a dual-washer mechanism with gasket is implemented, then resistance to unintended rotational movement is improved, but manufacturing complexity increases
Solution Approach 1:
The anti-rotation mechanism is segmented into distinct functional components: the dual-washer structure provides mechanical constraint, while the gasket provides friction-based resistance. This segmentation allows each component to be manufactured independently using standard processes, then assembled together. The first and second washers can be produced separately and then positioned relative to each other, simplifying manufacturing compared to creating a single complex integrated part.
Solution Approach 2:
The mechanism combines different material properties: the washers provide structural rigidity and mechanical constraint, while the gasket (typically elastomeric) provides friction-based resistance to rotation. This composite approach using materials with complementary properties achieves superior resistance to unintended rotational movement while maintaining ease of manufacture, as each material can be selected and processed for its optimal performance.
4Force
If torque elements are made adjustable by adding or subtracting elements, then force adjustment capability is improved, but device complexity increases
Solution Approach 1:
Instead of providing continuous or fine-grained adjustment of torque, the system uses discrete torque elements that can be added or removed in predetermined increments. This partial adjustment approach provides sufficient force control for typical display mounting applications without requiring complex continuous adjustment mechanisms. The discrete nature of the adjustment simplifies the device structure compared to systems with continuous variable torque control.
