Solution Overview

Problem

Existing ladder safety devices for securing ladders to gutters are time-consuming and error-prone due to the fixed angle of attachment, requiring users to manually adjust and secure the ladder after it is positioned at a specific angle, which can lead to slipping and tipping.

Innovation Solution

A ladder head safety device with an adjustable insertion device and actuating mechanism that allows for stepless adjustment of the ladder's angle relative to the gutter, enabling secure fastening to any rung and easy positioning at a 70-degree angle, while allowing for lateral movement and locking to prevent slipping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the securing element is fixed to a rung before setting up, then the ladder angle is predetermined, but the attachment process becomes time-consuming and error-prone

Engineering Contradiction:
Improveladder angle accuracyVSAvoidattachment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The securing element is made adjustable along the stile with a locking mechanism, allowing it to be positioned dynamically after the ladder is set up at the correct angle, rather than being fixed in a predetermined position. This resolves the contradiction by enabling both accurate angle setting and quick attachment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The securing element is pre-equipped with an adjustable mechanism and locking feature, so that when the ladder is set up, the user only needs to attach and lock it in position without complex adjustments. This prepares the device in advance to reduce attachment time while maintaining angle accuracy.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the securing element is positioned at a fixed location, then the structure is simple, but the ladder angle cannot be freely selected

Engineering Contradiction:
Improveladder angle selectionVSAvoidsecuring element structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The securing element can be adjusted to different positions along the stile and locked in place, providing variable ladder angle selection. The adjustment mechanism includes a locking feature that maintains the selected position, achieving adaptability without excessive complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The securing element is divided into an adjustable portion and a locking portion, allowing independent adjustment and securing functions. This segmentation enables angle versatility while keeping each component relatively simple in structure.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the user must remember the rung position after laying the ladder, then the initial setup is simple, but the attachment process becomes error-prone

Engineering Contradiction:
Improveattachment easeVSAvoidattachment accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The adjustable securing element allows the user to directly position it at the appropriate location on the stile after setting up the ladder, eliminating the need to remember rung positions. The self-adjusting mechanism makes the process intuitive and accurate without requiring memory or complex calculations.

Inventive Principle:
Principle #25Self-service
