Solution Overview

Problem

Existing locking systems for doors and windows are not optimal as they require manual activation and may not provide simultaneous and secure locking from both inside and outside.

Innovation Solution

The Skiles Locking System incorporates a Kwikset tubular locking cylinder with multiple internal spring-loaded sliding bolts and floating locks, allowing for automatic locking when the door is closed and enabling activation from either side using a key, button, or electronic keyless device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional single lock mechanism is used, then the device complexity is low, but the reliability of locking is insufficient and cannot provide simultaneous secure locking from both inside and outside

Engineering Contradiction:
Improvelocking securityVSAvoidlocking mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking system is divided into multiple independent sliding bolts (at least two) that can be activated simultaneously. Each bolt operates independently but contributes to the overall locking security, allowing the system to achieve higher reliability through distribution of function across multiple components rather than relying on a single lock mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines multiple sliding bolts into a single integrated locking system that can be activated by one action from either inside or outside the door. The bolts work together as a unified mechanism, merging their individual functions to provide simultaneous secure locking across multiple points, thereby enhancing reliability without proportionally increasing operational complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If manual activation of a single lock is required, then the ease of operation is reduced and time is lost, but the device complexity remains low

Engineering Contradiction:
Improvelocking operation convenienceVSAvoidlocking mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The sliding bolts are pre-positioned and spring-loaded within the locking mechanism, ready for immediate engagement. When activation occurs from either inside or outside, the bolts are already in position to slide into the locked state without requiring manual manipulation of each individual bolt, thereby improving ease of operation through preliminary preparation of the locking components.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The locking system is designed with universal activation capability, allowing the same mechanism to be operated from both inside and outside the door using the same simple action. This multi-functional design eliminates the need for different operating procedures for different sides, significantly improving ease of operation while maintaining relatively simple device architecture.

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

3Adaptability or versatility

If a locking system allows activation from only one side, then the device complexity is low, but the adaptability is reduced and cannot respond to emergencies from either side

Engineering Contradiction:
Improveactivation flexibilityVSAvoidlocking mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The locking mechanism incorporates universal activation capability that responds to input from either inside or outside the door equally. The same sliding bolt mechanism and control system handle operations from both sides, providing flexible adaptability for different usage scenarios including emergency situations without requiring separate locking systems for each side.

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

Solution Approach 2:

The locking system dynamically adapts to activation from either side through its spring-loaded sliding bolt design. When force is applied from inside or outside, the bolts dynamically respond by sliding into the locked position regardless of direction, providing versatile adaptability while maintaining a relatively simple mechanical structure that automatically adjusts to the activation source.

Inventive Principle:
Principle #15Dynamics
