Solution Overview

Problem

Existing nut stacking mechanisms for slat structures create an unwanted opening between the first slat and the adjacent construction surface when slats are fully extended, leading to gaps in protection against solar radiation, precipitation, and aesthetic issues.

Innovation Solution

A nut stacking mechanism with a rotatable spindle, movable nuts, and displacement elements that prevent absolute rotation while allowing relative movement, and a stacking element to limit sliding, ensuring a defined boundary between the stacking and sliding zones, thus eliminating the need for additional screening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the slats are fully driven out in the sliding zone, then the slats can extend distributed over the surface providing screening, but an opening is formed between the first slat and the adjacent construction surface

Engineering Contradiction:
Improveextension distance of slatsVSAvoidopening allowing solar radiation and precipitation
Core Design Contradiction:
Length of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a dynamic adjustment mechanism where the distance between the first slat and the adjacent construction surface can be varied. By making the stacking zone length adjustable, the system can dynamically adapt to different requirements, allowing the opening to be minimized or eliminated when needed while maintaining the ability to extend slats for screening when required.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of the stacking zone length to resolve the contradiction. By adjusting the length of the stacking zone, the system can control the position of the first slat relative to the adjacent construction surface, thereby controlling the opening size. This parameter change allows the system to eliminate the opening harmful effect while preserving the slat extension function.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If a separate permanent screening is provided for the opening, then protection against solar radiation and precipitation is improved, but device complexity and cost increase

Engineering Contradiction:
Improveprotection against solar radiation and precipitationVSAvoidadditional permanent screening structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent makes the slat structure itself multi-functional by enabling it to serve both as the screening element and as the element that controls the opening. By adjusting the stacking zone length, the same slat structure can provide protection against solar radiation and precipitation by eliminating the opening, without requiring a separate permanent screening. This universal approach eliminates the need for additional structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent extracts the function of closing the opening from the proposed separate permanent screening and integrates it into the existing slat displacement mechanism. By adjusting the stacking zone parameter, the slat structure itself performs the function of closing the opening, eliminating the need to add a separate screening component.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the stacking zone length is fixed, then the mechanism structure is simpler, but the ability to adapt to different screening requirements is reduced

Engineering Contradiction:
Improveadjustment of stacking and sliding zonesVSAvoiddisplaceable boundary mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces dynamics to the stacking zone length by making its boundary displaceable. This allows the stacking zone length to be adjusted according to different screening requirements, enhancing adaptability. The dynamic adjustment capability enables the system to optimize performance for various applications without requiring a completely different structure.

Inventive Principle:
Principle #15Dynamics
