Solution Overview

Problem

Existing grill designs, particularly charcoal grills, face difficulties in easily removing and reinstalling the lid, which complicates initial assembly and limits the use of accessories due to non-removable or complicated hinge systems.

Innovation Solution

A hinge assembly that allows the lid and associated lid bracket to be removably secured to the bowl bracket, featuring a spring-assisted mechanism with a keyhole-shaped lid lock slot and alignment pins, enabling safe and convenient removal and reinstallation, while a stop limits the lid's opening angle for safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the lid is hinged to the bowl using known hinges, then the lid remains securely attached during operation, but the lid cannot be easily removed or is only removable by complicated disassembly

Engineering Contradiction:
ImproveEase of lid removalVSAvoidHinge disassembly complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The hinge assembly is divided into separate components: a hinge body attached to the bowl, and a hinge arm attached to the lid. These segments connect through a simplified pin and slot mechanism that allows easy detachment without complicated disassembly procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge pin is extracted as a separate, removable component that can be easily removed to detach the lid from the bowl. This extraction of the connecting element enables simple separation of the hinge assembly into its component parts.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If the lid is permanently hinged to the bowl, then the hinge structure provides stable support, but accessories like rotisserie systems cannot be easily installed

Engineering Contradiction:
ImproveAccessory compatibilityVSAvoidHinge structure stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The hinge transitions from a static, permanent connection to a dynamic, adjustable connection. The lid can be detached when accessories need to be installed, and reattached when not needed, allowing the system to adapt between different operational states.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The hinge design serves multiple functions: it provides stable support during normal grilling operations, and enables accessory installation by allowing lid removal. This multi-functionality accommodates both permanent hinging needs and accessory compatibility requirements.

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

3Adaptability or versatility

If a removable hinge mechanism is implemented, then the lid can be easily detached for accessory installation, but the mechanism becomes more complex

Engineering Contradiction:
ImproveLid removabilityVSAvoidHinge mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hinge uses simple, easily replaceable components such as a basic pin and slot mechanism rather than complex, precision-engineered detachable connections. This approach prioritizes simplicity and ease of manufacture over permanent durability, allowing for easy replacement if needed.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
