Solution Overview

Problem

Existing reusable water bottles lack an integrated carabiner handle that cannot be removed, and existing solutions with carabiner clips introduce additional components that can be lost.

Innovation Solution

A beverage container with a cap that integrates a carabiner, where the carabiner is fixedly secured within a through-bore of the cap, allowing it to rotate, providing a secure and integrated carrying mechanism without additional extending components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a carabiner clip is used as a connecting element between the integrated handle and the object, then the carrying function is improved, but the device complexity increases and the carabiner can be removed and lost

Engineering Contradiction:
Improvecarrying functionVSAvoidadditional component
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The carabiner is merged with the cap by inserting the carabiner body through a through-bore in the cap, making the carabiner an integral part of the cap assembly. This eliminates the need for separate connecting elements and prevents the carabiner from being lost, as it is now fixed to the cap structure.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If the handle is integrated into the cap as a closed loop, then the device complexity is reduced, but the ability to connect to objects requires additional devices

Engineering Contradiction:
Improvehandle structureVSAvoidconnection capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The carabiner's clipping function is merged with the cap structure by positioning the carabiner body through the through-bore, allowing the cap to directly attach to objects via the carabiner mechanism without requiring separate connecting devices.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the carabiner is fixedly secured within the through-bore of the cap, then the reliability is improved by preventing loss, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveattachment securityVSAvoidthrough-bore alignment
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The through-bore acts as an intermediary structure that receives and secures the carabiner body. The bore provides a defined pathway that guides the carabiner into its fixed position, reducing the precision requirements compared to direct fixation methods.

Inventive Principle:
Principle #24Intermediary (Mediator)
