Innovation Solution
A shading assembly comprising a frame with rods, connectors, and a flexible panel that couples to the chair, featuring a design with pivotally connected tubes, deformable clips, and zip ties to secure the panel over the frame, ensuring shading and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid shading structure is used, then structural integrity is improved, but adaptability to different chair types deteriorates
Solution Approach 1:
The frame is divided into multiple rod segments (first rods, second rods, third rods) that can be independently positioned and connected. This segmentation allows the structure to adapt to different chair geometries while maintaining overall structural integrity through the connectors that join the segments together.
Solution Approach 2:
The frame incorporates movable and adjustable components including pivotally connected tubes and deformable clips that allow the structure to dynamically adapt to different chair types. The rods can be positioned at various locations and angles, transforming the rigid structure into a dynamic system that maintains strength while achieving versatility.
2Adaptability or versatility
If a flexible panel is used, then adaptability to chair shapes is improved, but light impenetrability deteriorates
Solution Approach 1:
The patent uses a flexible panel made of a flexible fabric material that can conform to various chair shapes and frame configurations. The panel is stretched taut across the frame structure, which maintains its light-blocking properties while allowing the panel itself to be flexible and adaptable to different geometries.
Solution Approach 2:
The shading assembly combines a flexible fabric panel with a rigid or semi-rigid frame structure. This composite approach allows the flexible panel to adapt to chair shapes while the frame provides the structural support needed to maintain the panel's tension and light-blocking effectiveness.
3Ease of operation
If multiple connectors are used, then ease of coupling to different chairs is improved, but device complexity deteriorates
Solution Approach 1:
The connectors are designed with multi-functional capabilities: clips can deform to grip different surfaces, tubes can pivot to accommodate various angles, and the system can use different fastening methods (clips, ties, or other fasteners). This universality allows a single connector design to handle multiple coupling scenarios, reducing the need for multiple specialized components.
Solution Approach 2:
The connectors utilize parameter changes in their operation - the clips deform elastically to grip different chair structures, the tubes pivot through different angles, and the fastening mechanism transitions between different states (open/closed, engaged/disengaged). These parameter changes enable the connectors to adapt to various chair types without requiring complex mechanical adjustments.
4Reliability
If the panel is securely attached, then shading effectiveness is improved, but ease of installation deteriorates
Solution Approach 1:
The frame structure is pre-assembled with connectors attached to the rods before the panel is installed. This preliminary action allows the frame to be prepared and adjusted to the desired configuration independently, and then the panel can be simply stretched and secured to the pre-positioned frame, making installation easier while ensuring secure attachment.
Solution Approach 2:
The panel attachment system utilizes self-gripping connectors such as deformable clips that automatically secure the panel to the frame rods when the panel is stretched taut. The tension from stretching the panel causes the clips to deform and grip the rods, providing self-service securing without requiring additional fastening actions or complex installation procedures.
