Solution Overview

Problem

Existing push button release police batons lack an efficient mechanism for collapsing extended sections into a compact form, relying on dual cam mechanisms, ball bearing locking, or manual release mechanisms that are not always reliable or user-friendly.

Innovation Solution

A multi-stage push button release baton utilizing a single axially positioned push button clutch alignment rod to align and disengage clutch locking mechanisms, allowing telescoping sections to collapse seamlessly into a handle end section, with each section locking in place using clutch locking mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dual cam mechanism or ball bearing locking mechanism is used, then the baton sections can be locked in extended position, but the collapse mechanism becomes complex and less reliable

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

Solution Approach 1:

The patent combines the locking and collapsing functions into a single integrated mechanism. The push button simultaneously controls the release of multiple clutch locking mechanisms through a shared release rod, merging what would otherwise be separate locking and collapsing systems into one unified operation that improves reliability while reducing complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The release rod serves multiple functions: it acts as both the actuating mechanism for collapsing the baton and the alignment structure for the clutch locking mechanisms. This multi-functional component eliminates the need for separate collapse mechanisms, thereby reducing overall device complexity while maintaining reliable operation.

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

2Ease of operation

If manual release mechanisms are used, then the baton can be collapsed, but the operation becomes difficult and not user-friendly

Engineering Contradiction:
Improvecollapse operation easeVSAvoidrelease mechanism reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The clutch locking mechanisms are designed to automatically align and engage with the release rod's grooves when the baton sections are in the correct position. This self-alignment feature eliminates the need for precise manual positioning by the user, making the operation intuitive and user-friendly while maintaining reliable release function.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The release rod acts as an intermediary mechanism that translates the simple push button action into the coordinated release of multiple clutch locking mechanisms. This intermediary component simplifies the user's interaction to a single push motion while ensuring reliable and synchronized release of all locking points.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If multiple clutch locking mechanisms are used, then each section can be securely locked, but the alignment and operation becomes complex

Engineering Contradiction:
Improvesection locking securityVSAvoidclutch alignment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The release rod features asymmetrically positioned grooves that correspond to the specific alignment requirements of each clutch locking mechanism. This asymmetric design ensures that each clutch engages at the correct position and orientation, providing secure locking while simplifying the alignment process through built-in mechanical guidance rather than requiring complex external alignment procedures.

Inventive Principle:
Principle #4Asymmetry
