Solution Overview

Problem

Existing flushing panel structures for concealed water tanks face challenges in accommodating varying installation environments, requiring cutting of the protection frame to fit the wall, which is inconvenient and costly, and lacks adjustability of the cylinder's position.

Innovation Solution

An adjustable apparatus featuring a square outer cover with a built-in cylinder and a locking release device, allowing for lateral and longitudinal adjustment of the cylinder's position without cutting, using a parallelogram structure and clamping teeth for tool-free adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the protection frame body is made higher than the wall to ensure sufficient height, then the structural integrity is improved, but it cannot fit with the wall and requires cutting, increasing installation complexity and cost

Engineering Contradiction:

Improvestructural integrityVSAvoidinstallation convenience

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The protection frame body is designed with a movable structure that can adjust its height relative to the wall. The frame includes a sliding mechanism with guide rails and locking components, allowing it to move between extended and retracted positions. This dynamic adjustment capability enables the frame to adapt to different wall heights without requiring cutting, thus maintaining structural integrity while improving installation convenience.

Inventive Principle:

Principle #15Dynamics

2Shape

If the protection frame body is cut to fit the wall, then the fit with the wall is improved, but the frame is damaged and cannot be reused, increasing manufacturing cost

Engineering Contradiction:

Improvefit with wallVSAvoidreusability and cost

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the protection frame body is reserved with enough height for all installation scenarios, then the adaptability is improved, but the manufacturing cost increases

Engineering Contradiction:

Improveapplicability to different environmentsVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The protection frame body's height parameter is made variable through the sliding mechanism. Instead of manufacturing different fixed-height frames for different installation scenarios, a single frame design with adjustable height parameters achieves universal applicability, reducing manufacturing costs while maintaining adaptability.

Inventive Principle:

Principle #35Parameter changes

4Ease of manufacture

If the cylinder position is fixed in the protection frame, then the manufacturing process is simplified, but the installation position cannot be adjusted to match different flushing panel positions

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidcylinder position adjustability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The cylinder mounting structure includes a sliding mechanism with guide rails that allow the cylinder to move laterally and vertically within the protection frame. Positioning holes and locking components enable the cylinder to be secured at multiple predetermined positions, providing adjustability while maintaining a relatively simple manufacturing process.

Inventive Principle:

Principle #15Dynamics
