Hand tools

Open-End Ratcheting Wrench

A versatile hand-tool invention for professional and DIY markets, designed to combine familiar ratcheting-wrench use with access to in-line nut fasteners.

Evolution and development of the Open-End Ratcheting Wrench
OERW

Conventional ratcheting. Plus in-line access.

The OERW handles common ratcheting-wrench tasks while also addressing in-line nut fasteners that closed-ring designs cannot access.

Compact headStrong architectureDirect cogwheel accessManufacturability in mind
✓
Access: designed for tight spaces and in-line fittings.
✓
Handling: direct cogwheel manipulation supports tactile use when the tool is out of sight.
✓
Production: minimum components and generic tooling principles support cost-effective manufacture.
Commercial position: patented invention with working prototypes; seeking an established hand-tool manufacturer or brand for licensing and commercialisation.

Sanitaryware

Self-Ventilating Toilet

A patented toilet technology that draws bowl air directly from the commode and vents it to the toilet’s standard sewerage connection through a dedicated internal air pathway designed to meet applicable building-code requirements.

SVT

Remove toilet odour at the source.

The SVT extracts air from the commode before odour spreads into the bathroom and routes it directly to the toilet’s standard sewerage connection. Its compact air-handling path is protected by the SVT water-seal arrangement and is designed around applicable building-code requirements.

Standard sewer connectionNo room-side civil workCommode or smart-seat integrationStandard power supply
✓
Compact integration: the SVT architecture can be engineered into the commode itself or integrated into a smart toilet seat/bidet.
✓
Plug-and-play installation: the intended bathroom installation uses the toilet’s normal sewer connection plus a standard power supply, without additional ducting or civil work in the toilet-room space.
✓
Manufacturer fit: the technology is intended to add a differentiated odour-control feature within existing sanitaryware and smart-toilet product families.

Market potential & viability

Growing market. Published market estimates differ in absolute size, but both point to continued growth. Custom Market Insights estimates the global smart-toilet market at US$10.70 billion in 2025 and US$31.50 billion by 2034; Fortune Business Insights also projects growth through 2034, although at a lower absolute market-size estimate.12

Strategic advantage. Real-building ventilation systems can suffer from duct leakage, inadequate make-up air, maintenance and balancing issues. SVT’s product-level approach offers sanitaryware manufacturers a way to address odour at source without adding a separate bathroom exhaust route or major room-side modifications.3

About HMinventions

Built for manufacturers, not just inventors.

Our role is to turn practical problems into licensable product solutions that established manufacturers can adapt to their own product architecture, brand and channels.

Engineering + manufacturing perspective

With decades of engineering and manufacturing experience, we develop practical solutions with product integration, tooling, production cost and end-user experience in mind.

Commercial objective

We are actively seeking manufacturers with established marketing channels to evaluate, license and commercialise inventions that can add differentiation to their product portfolios.

01

Review the invention

Start with the non-confidential overview, prototype demonstration and product fit.

02

Technical discussion

Discuss manufacturability, engineering questions, market positioning and integration.

03

Define the route

If there is mutual interest, agree the next evaluation steps and a suitable licensing/commercial structure.
