Solution Overview

Problem

Current end-effectors in manufacturing environments require frequent and tedious adjustments for different tasks, leading to inefficiencies and space inefficiencies due to the need for multiple locking devices, which are not easily integrated for simultaneous actuation.

Innovation Solution

An integrated locking device combining both linear and rotary locking mechanisms, mounted on different sides of a housing to reduce device height and enable simultaneous actuation, allowing for quick reconfiguration and secure locking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple separate locking devices are used for linear and rotary operations, then each locking function can be performed independently, but the device height increases and reconfiguration time increases

Engineering Contradiction:
Improvereconfiguration speedVSAvoiddevice height
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The patent combines a linear locking mechanism and a rotary locking mechanism into a single integrated locking device. The linear locking mechanism includes a linear actuator and locking fingers, while the rotary locking mechanism includes a rotary actuator and locking lugs, both housed within a common housing. This merging allows both linear and rotary locking functions to be performed simultaneously or independently through a single integrated unit, reducing the overall device height and enabling faster reconfiguration compared to using separate locking devices.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple separate locking devices are used, then each locking function can be independently controlled, but the device mass and space requirements increase

Engineering Contradiction:
Improvetooling reconfigurabilityVSAvoiddevice mass
Core Design Contradiction:
Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The integrated locking device provides multi-functionality by incorporating both linear locking and rotary locking capabilities within a single device. The linear locking mechanism can secure tooling components in linear positions, while the rotary locking mechanism can secure rotational positions. This universal design allows a single device to replace multiple separate locking devices, reducing overall device mass and space requirements while maintaining full adaptability for various tooling reconfiguration needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If traditional separate locking mechanisms are used, then each mechanism can be optimized for its specific function, but the overall system complexity and setup time increase

Engineering Contradiction:
Improvelocking securityVSAvoidnumber of locking devices
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple locking mechanisms into a single integrated device while maintaining the functional optimization of each mechanism. The linear locking mechanism retains its optimized design with linear actuators and locking fingers for secure linear positioning, while the rotary locking mechanism maintains its optimized design with rotary actuators and locking lugs for secure rotational positioning. By integrating these mechanisms into one device with a common housing and coordinated actuation system, the patent reduces system complexity and setup time while preserving the reliability and locking security of each individual mechanism.

Inventive Principle:
Principle #5Merging (Combining)
