Solution Overview

Problem

Public transportation stations and outdoor public spaces often lack adequate sunshades, exposing users to harmful sunlight, especially in areas with physical or technical challenges that prevent shelter installation.

Innovation Solution

A sunshade system with a rotatable pane mounted on a vertical axis, equipped with a rotation control apparatus that allows for adjustable shading, includes features like braking systems, user-controlled immobilization devices, and indexing mechanisms to ensure safe and controlled orientation, and can be integrated with signage, lighting, and photovoltaic panels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the pane is made rotatable to provide adjustable shading, then the adaptability and shading effectiveness are improved, but the risk of uncontrolled rotation and safety hazards increases

Engineering Contradiction:
Improveshading adjustment capabilityVSAvoidrotation control safety
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces manual mechanical rotation control with an electric motor system. The motor (24) is connected to the pane (6) through a transmission mechanism, allowing automated and controlled rotation to adjustable positions. This substitution provides precise control over pane orientation while eliminating the safety hazards associated with uncontrolled manual rotation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent incorporates a control system with feedback mechanisms including position sensors and emergency stop functionality. The control unit (23) receives feedback about the pane's position and automatically stops rotation at predetermined shaded positions. The emergency stop button enables immediate cessation of rotation, providing feedback-based safety control to prevent uncontrolled movement.

Inventive Principle:
Principle #23Feedback

2Reliability

If a rotation control apparatus is added to control pane rotation, then the safety and control precision are improved, but the device complexity increases

Engineering Contradiction:
Improverotation control safetyVSAvoidcontrol system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple control functions into an integrated control unit (23) that combines the motor controller, position sensing, and emergency stop functionality. The control unit is integrated with the mounting structure, and the motor is coupled directly to the pane rotation mechanism, reducing the number of separate components and simplifying the overall system architecture.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control unit (23) serves multiple functions: it controls the motor-driven rotation, determines predetermined shaded positions, responds to emergency stop commands, and manages the overall operation of the sunshade system. This multi-functionality reduces the need for separate control components, thereby managing device complexity while maintaining comprehensive safety and control capabilities.

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

3Ease of operation

If the sunshade is installed in public spaces with physical or technical challenges, then the accessibility and user protection are improved, but the installation feasibility and structural stability may be compromised

Engineering Contradiction:
Improveuser accessibility to shadeVSAvoidinstallation feasibility
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent divides the sunshade system into modular components: a mounting structure that can be attached to various surfaces (walls, ceilings, poles), a separate pane assembly with integrated motor and control, and independent support elements. This segmentation allows the system to be installed in diverse public spaces including areas with limited ground space or difficult access, as each module can be adapted to different installation environments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs a dynamic mounting system with adjustable and adaptable support structures. The mounting structure can be configured for different installation scenarios (wall-mounted, ceiling-mounted, or pole-mounted), and the motorized rotation mechanism allows the shade to dynamically adjust to optimal positions based on sun movement and user needs, enhancing both installation flexibility and operational effectiveness in challenging public spaces.

Inventive Principle:
Principle #15Dynamics
