Solution Overview

Problem

Existing anti-collision strips are inefficient to apply and maintain on corners of various angles, often peeling due to resilience and providing inadequate protection, especially for angles other than 90 degrees.

Innovation Solution

The anti-collision strip features a design with a first and second side edge mounting portion connected by an intermediate portion, incorporating inner side grooves that reduce resilience and allow for secure adhesion to corners of various angles without peeling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If right-angle anti-collision strip is used, then it can be adhered to right-angle corners, but it cannot be applied to corners less than 90° or greater than 90° and will peel off over time due to resilience

Engineering Contradiction:

Improveadaptability to various corner anglesVSAvoidadhesion stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The anti-collision strip is divided into a mounting portion and an intermediate portion, with the mounting portion having a different cross-sectional shape (trapezoidal or triangular) than the intermediate portion (rectangular). This segmentation allows the mounting portion to adapt to various corner angles while the intermediate portion maintains structural integrity and provides adequate thickness for protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting portion is designed with asymmetric cross-sectional shapes (trapezoidal or triangular) that can accommodate different corner angles, while the intermediate portion maintains a symmetric rectangular cross-section. This asymmetric design enables the strip to adapt to corners ranging from acute to obtuse angles without peeling.

Inventive Principle:

Principle #4Asymmetry

2Ease of operation

If planar anti-collision strip with grooves is used, then it can be folded and adhered to corners expediently, but the aesthetic appearance is reduced and the thickness at grooves is thin providing inadequate protection

Engineering Contradiction:

Improveease of applicationVSAvoidaesthetic appearance and protective thickness

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

Instead of creating grooves by removing material in the same plane (which reduces thickness and aesthetics), the patent introduces a folding dimension. The mounting portion is designed to fold along a folding line, creating a three-dimensional structure that adapts to corners while maintaining uniform thickness throughout the strip.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If planar anti-collision strip with grooves is used, then it can be folded to fit corners, but the edges of corners align at the grooves reducing protective effect

Engineering Contradiction:

Improvefit to various corner anglesVSAvoidprotective effect at corner edges

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The strip is segmented into a mounting portion and an intermediate portion, where the mounting portion folds to adapt to corner angles while the intermediate portion maintains full thickness. This ensures that the thickest part of the strip (the intermediate portion) always protects the corner edge, regardless of the corner angle.

Inventive Principle:

Principle #1Segmentation

4Strength

If right-angle anti-collision strip is used, then it can protect right-angle corners, but a long time is needed to apply double-sided tape to both sides

Engineering Contradiction:

Improveprotective effectVSAvoidapplication time

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The mounting portion is pre-formed with the appropriate cross-sectional shape and folding structure during manufacturing. This preliminary action eliminates the need for users to manually apply double-sided tape to both sides and fold the strip, significantly reducing application time while maintaining protective effectiveness.

Inventive Principle:

Principle #10Preliminary action

AI summary

The present invention relates to the technical field of anti-collision strips, and discloses an anti-collision strip and a bundle roll of anti-collision strip. The anti-collision strip comprises a first side edge mounting portion (2), an intermediate portion (3), and a second side edge mounting portion (4) connected in sequence along a width direction of the anti-collision strip (1), the first side edge mounting portion (2), the intermediate portion (3) and the second side edge mounting portion (4) extending along a length direction of the anti-collision strip, wherein a first inner side groove (5) extending along the length direction of the anti-collision strip is formed at a junction of a first inner side surface (21) of the first side edge mounting portion (2) and an intermediate inner side surface (31) of the intermediate portion (3), a second inner side groove (6) extending along the length direction of the anti-collision strip is formed at a junction of a second inner side surface (41) of the second side edge mounting portion (4) and the intermediate inner side surface (31) of the intermediate portion (3). The first inner side groove and the second inner side groove provide buffer space. The anti-collision strip can be stably and reliably adhered on corners having various angles to provide protection, can avoid peeling due to rebound force, and has a good protection effect on the edges of the corners, thereby improving the convenience of use.
