Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a U-shaped iron frame is used to support the shade, then the structural strength is improved, but the weight and volume increase significantly
Solution Approach 1:
The supporting seat is divided into multiple components: a first plate, a second plate, and a rod unit with axle and transmission rod. These segmented parts can be assembled together to form the supporting structure, replacing the monolithic U-shaped iron frame. The segmentation allows for reduced individual component sizes while maintaining overall structural integrity through modular assembly.
Solution Approach 2:
The patent employs composite construction by combining different materials with complementary properties. The first and second plates are made of lightweight plastic material, while the axle and transmission rod provide mechanical strength. This composite approach achieves both weight reduction and structural strength requirements.
2Stability of the object's composition
If a U-shaped iron frame is used to support the shade, then the structural stability is improved, but the assembly and detachment process becomes time-consuming and laborious
Solution Approach 1:
The supporting seat is segmented into detachable components (first plate, second plate, rod unit) that can be quickly assembled and disassembled. The rod unit with its axle and transmission rod forms a modular subsystem that can be independently installed, enabling rapid assembly without the time-consuming process of constructing a monolithic U-shaped frame.
Solution Approach 2:
The supporting seat transitions from a static, fixed U-shaped structure to a dynamic, reconfigurable assembly. The rod unit can be rotated and positioned at different angles, and the entire supporting seat can be detached and reattached easily. This dynamic design enables quick assembly and adaptation while maintaining structural stability during use.
3Strength
If a U-shaped iron frame is used to support the shade, then the structural integrity is improved, but the transportation convenience deteriorates
Solution Approach 1:
The supporting seat is divided into compact, detachable segments including the first plate, second plate, and rod unit. These segmented components can be easily packed and transported separately, then quickly assembled at the destination. The modular design eliminates the bulk and difficulty of transporting a large U-shaped iron frame while maintaining structural integrity when assembled.
Solution Approach 2:
The supporting seat design allows for compact storage and transport in a different dimensional state. The rod unit can be rotated and the plates can be positioned to minimize the occupied space during transport, then expanded to the full functional configuration when installed. This dimensional transformation enables easy transportation without compromising structural integrity during use.
4Area of stationary object
If the width of the U-shaped iron frame is increased to match a wider shade, then the shade coverage is improved, but the volume and weight increase proportionally
Solution Approach 1:
The supporting seat is segmented into modular components that can be configured to match different shade widths. The first plate, second plate, and rod unit can be arranged in different configurations, allowing the supporting seat to adapt to various shade dimensions without requiring a proportionally larger volume. The modular nature enables customization without increasing overall bulk.
Solution Approach 2:
The supporting seat employs a dynamic, adjustable design where the rod unit can be rotated and positioned at different angles, and the plates can be arranged to accommodate various shade widths. This dynamic configurability allows the supporting seat to adapt to different shade dimensions without requiring a fixed, proportionally larger structure, thereby reducing unnecessary volume and weight.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The new design significantly reduces the overall volume and weight of the supporting seat, enabling faster and more convenient assembly and detachment, while enhancing engagement reliability and user convenience, and preventing energy storage failures in the returning element.
Implementation Method 1
A folding shade according to the present invention comprises a supporting seat including a first plate and a second plate opposite to the first plate. The first plate has an abutting portion. A rod unit is connected between the first plate and the second plate. The rod unit includes an axle and a transmission rod rotatably disposed around the axle. An annular space is defined between the transmission rod and the axle. A returning element is mounted around the axle and is connected to the transmission rod.
Implementation Method 2
A braking mechanism is disposed in the annular space. The braking mechanism includes a limiting member. The abutting portion of the first plate releasably abuts against the limiting member to move the limiting member along the longitudinal axis.
