Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pelican hooks are cumbersome and difficult to operate, requiring two hands and causing users to often forego safety equipment when climbing structures, leading to accidents and injuries.
Innovation Solution
A pelican hook design featuring a gate mechanism with a gate actuator and lock actuator that allows single-handed operation, enabling users to engage and disengage support members without letting go of the hook.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pelican hook design is used, then safety function is provided, but operation becomes cumbersome and difficult
Solution Approach 1:
The patent combines the lock actuator and gate actuator into a single integrated gate mechanism assembly. The lock actuator includes a lock arm and the gate actuator includes a gate arm, both connected to common mounting structures and sharing the same actuation space. This merging allows both locking and gate opening functions to be controlled from a single location, enabling one-handed operation while maintaining safety reliability.
Solution Approach 2:
The gate mechanism is designed with multi-functionality, where the lock actuator serves both to engage and disengage the lock, and the gate actuator serves both to open and close the gate. Additionally, the mechanism allows operation with either hand (left or right), providing universal usability. This multi-functionality resolves the contradiction by maintaining safety functions while greatly improving ease of operation.
2Reliability
If two hands are required to operate pelican hook, then secure operation is achieved, but climbing efficiency decreases
Solution Approach 1:
The patent merges the lock actuator and gate actuator into a single integrated assembly that can be operated with one hand. The lock actuator and gate actuator share common mounting structures and control mechanisms, allowing both functions (locking and gate operation) to be performed simultaneously with one hand, thus improving climbing efficiency while maintaining secure operation through the integrated design.
Solution Approach 2:
The gate mechanism is segmented into distinct functional components (lock actuator with lock arm, gate actuator with gate arm) that are independently controllable but integrated in space. This segmentation allows each function to be optimized separately while their integration enables one-handed operation, resolving the contradiction between secure operation and climbing efficiency.
3Ease of operation
If user must let go of pelican hook to operate it, then full hand control is possible, but continuous safety support is compromised
Solution Approach 1:
The patent merges both the lock actuator and gate actuator into a single integrated mechanism that can be operated while maintaining grip on the hook body. This allows continuous safety support as the user never lets go of the hook, yet full hand control is possible through the unified actuation design that responds to single-handed input for both locking and gate functions.
4Shape
If stretch to reach pelican hook is required, then proper positioning is achieved, but physical exhaustion increases
Solution Approach 1:
The patent merges the lock actuator and gate actuator into a single integrated assembly positioned at the same location on the hook body. This unified positioning allows the user to operate both functions without stretching or repositioning, eliminating physical exhaustion while maintaining proper positioning of both actuators for ergonomic access during climbing operations.

AI summary
Pelican hooks and related systems are disclosed. In one embodiment, the pelican hook includes a hook that defines a hook gap, a gate for the hook gap, and a gate mechanism. The gate is configured to be opened so as to open the hook gap and is configured to be closed so as to close the hook gap. The gate mechanism includes a gate actuator for opening the gate and a lock actuator for unlocking the gate. To do this, the gate mechanism is configured such that actuating the lock actuator toward the gate actuator unlocks the gate and such that actuating the gate actuator toward the lock actuator opens the gate. In this manner, the user can operate the pelican hook with a single hand and without having to let go of the pelican hook.
