Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Sliding door frames are vulnerable to damage during construction due to heavy traffic and equipment movement, as existing protective covers lack a robust and adaptable solution for comprehensive protection.

Innovation Solution

A two-piece protector unit comprising an inverted U-shaped sill riser cover and a flat flexible sill plate cover, connected via scoring marks and channel members for stability, providing a rigid and adjustable protection for the sliding door frame, including its vertical jamb component.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single-piece protective cover is used for the sliding door frame, then the protection is simple to install, but it cannot provide comprehensive coverage for both the sill plate and sill riser areas

Engineering Contradiction:

Improvecoverage areaVSAvoidprotector structure

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The protective cover is divided into two separate pieces: a sill plate cover and a sill riser cover. Each piece is optimized to cover specific areas of the sliding door frame, allowing comprehensive protection while maintaining simplicity in each individual component's installation

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If a rigid protective cover is used, then the protection is stable and secure, but it cannot be easily removed or repositioned during construction

Engineering Contradiction:

Improveprotector stabilityVSAvoidremovability

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The protective cover incorporates a flexible material that can be bent and shaped to fit around the sliding door frame components. This flexibility allows the cover to be easily installed, repositioned, and removed during construction while maintaining stability through friction and conformal fit against the frame surfaces

Inventive Principle:

Principle #15Dynamics

3Reliability

If a custom-fit protective cover is used for each specific door frame, then the protection is precise and effective, but the manufacturing cost and complexity increase

Engineering Contradiction:

Improveprotection effectivenessVSAvoidmanufacturing simplicity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The protective cover is designed with a universal configuration that can accommodate various sliding door frame sizes and configurations. The two-piece design with flexible material allows a single standard product to be adapted to multiple applications, providing precise protection without requiring custom manufacturing for each specific door frame

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A protector for a sliding door frame includes an inverted U-shaped sill riser cover and a sill plate cover and means for snapping the two covers together to form a rigid unitary unit for protecting the sliding door frame during construction.
