Solution Overview

Problem

Current windshield repair systems face inefficiencies due to the complexity and cost of external vacuum sources, which often fail to effectively evacuate contaminants and can contaminate the filling material, affecting the refractive index and repair quality.

Innovation Solution

A windshield repairing apparatus that creates a vacuum to evacuate contaminants using a piston assembly and holding chamber, isolating the filling material from contaminants and allowing for precise application to the damaged site, thereby improving the repair process without altering the refractive index.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external vacuum sources are used to evacuate contaminants, then the vacuum can be provided, but the system complexity and cost increase

Engineering Contradiction:

Improvevacuum evacuation effectivenessVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the vacuum generation function from external sources and relocates it to an internal piston assembly integrated within the repair tool. This allows the vacuum to be created locally at the damaged site without requiring complex external vacuum systems, conduits, or seals, thereby reducing overall system complexity while maintaining evacuation effectiveness.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The repair tool becomes self-sufficient by incorporating its own vacuum generation capability through the piston assembly. The tool creates its own vacuum environment independently without relying on external vacuum sources, eliminating the need for complex connections and seals between external components.

Inventive Principle:

Principle #25Self-service

2Reliability

If vacuum is provided through the filling material, then the damaged site can be evacuated, but the filling material becomes contaminated altering its refractive index

Engineering Contradiction:

Improvecontaminant evacuationVSAvoidrefractive index precision

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent segments the vacuum evacuation process from the filling material application. The piston assembly creates vacuum in a sealed chamber to evacuate contaminants, while the filling material is introduced separately through the same piston mechanism after evacuation is complete. This sequential separation prevents contamination of the filling material while achieving effective contaminant removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs contaminant evacuation as a preliminary action before introducing the filling material. The piston assembly first creates vacuum and removes all contaminants from the damaged site, then subsequently delivers the filling material into the evacuated space. This preliminary evacuation ensures the filling material remains uncontaminated and maintains its optical properties.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If seals are used to create hermetically sealed environment, then vacuum can be maintained, but the seals are susceptible to degradation over time

Engineering Contradiction:

Improvevacuum maintenanceVSAvoidseal durability

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent employs a flexible diaphragm or membrane within the piston assembly to create the hermetic seal. This flexible element deforms elastically during piston movement to maintain sealing while accommodating mechanical stress, avoiding the degradation issues associated with rigid seals. The flexible membrane can repeatedly flex without losing sealing effectiveness.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent replaces traditional mechanical seal systems with a flexible membrane-based sealing mechanism. Instead of using rigid seals that slide or rotate and are prone to wear, the system uses an elastic diaphragm that flexes to maintain the hermetic seal, significantly improving durability and resistance to degradation over time.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
