Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple roller tubes are mounted end-to-end with fixed brackets, then the structural stability is improved, but the alignment precision deteriorates due to misalignment of end and middle brackets
Solution Approach 1:
The bracket system transitions from fixed to adjustable, allowing dynamic repositioning of middle brackets along the roller tube to achieve precise alignment. The adjustable mechanism enables installers to move brackets to optimal positions and secure them, resolving the alignment precision issue while maintaining structural stability through secure fastening.
Solution Approach 2:
The invention changes the positional parameter of the middle brackets by introducing adjustment mechanisms that allow horizontal and vertical repositioning. This enables the brackets to be positioned at different locations along the roller tube and at different heights, achieving precise alignment of multiple roller tubes while maintaining structural integrity.
2Manufacturing precision
If middle brackets are repositioned to correct misalignment, then the alignment precision is improved, but the installation time increases due to removal and repositioning operations
Solution Approach 1:
The adjustable bracket system allows installers to perform preliminary positioning of middle brackets before final securing. The brackets can be temporarily positioned, adjusted to achieve precise alignment, and then firmly fastened, eliminating the need for repeated removal and repositioning operations.
Solution Approach 2:
The dynamic adjustment capability of the brackets enables precise alignment to be achieved during the initial installation phase rather than requiring subsequent adjustments. The adjustable mechanisms allow for fine-tuning of bracket positions while they are being installed, reducing the need for rework and saving installation time.
3Shape
If the blind fabric winding is adjusted to correct bottom bar misalignment, then the visual appearance is improved, but the device complexity increases due to additional adjustment operations
Solution Approach 1:
The invention introduces adjustable brackets with horizontal and vertical adjustment capabilities that allow the bottom bars of multiple roller tubes to be aligned at the same level. This structural adjustment eliminates the need for complex fabric unwinding and rewinding operations, simplifying the adjustment process while improving visual appearance.
Solution Approach 2:
The adjustable brackets serve as intermediaries that provide alignment adjustment at the structural level rather than requiring adjustment at the fabric level. By positioning the brackets correctly, the bottom bars are automatically aligned, eliminating the need for complex fabric manipulation operations.
4Manufacturing precision
If adjustable coupling members are added to the bracket system, then the alignment precision is improved, but the device complexity increases due to additional components
Solution Approach 1:
The adjustable coupling members are integrated into the bracket design to provide multiple functions: structural support, position adjustment, and alignment correction. This multi-functionality reduces the need for separate adjustment devices, minimizing the increase in device complexity while achieving improved alignment precision.
Solution Approach 2:
The coupling members enable independent adjustment of horizontal and vertical parameters of the middle brackets. This parameter adjustment capability is built into the bracket structure itself, allowing precise alignment to be achieved through simple mechanical adjustments rather than adding complex external adjustment mechanisms.

AI summary
An alignment bracket for a roller blind, comprising a base and a roller tube support securable to the base. First and second coupling members on the base and roller tube support permit an adjustment of the alignment of the roller tube support, and the end of a roller tube mounted thereon, relative to the base. Also provided is a blind fabric alignment device for a roller tube of a multi-tube roller blind. The alignment device comprises a drive coupling body securable to an end of a roller tube of the blind, a driven member mounted to the drive coupling body, a torque transfer mechanism secured to the driven member, and an adjuster. The torque transfer mechanism transfers rotational torque from the driven member to the drive coupling body through the adjuster. The adjuster permits an alteration of the rotational position of the driven member relative to the drive coupling body.
