Solution Overview

Problem

Conventional pressure cooker lids have fixed designs, making it costly and inefficient to produce different variants, as the entire unit must be redesigned for design changes or variations, limiting design flexibility and increasing production costs.

Innovation Solution

A modular lid handle design where the functional elements are integrated into a removable technology module, allowing for easy replacement of a cover module, which only serves as a cladding element, enabling various design variants and reducing production costs by allowing customers to change the cover module's shape or color.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the entire lid handle unit is redesigned for different design variants, then design flexibility is improved, but production costs increase and production time is extended

Engineering Contradiction:
Improvedesign flexibilityVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The lid handle is divided into two independent modules: a technology module containing all functional elements (pressure regulator, safety valve, pressure gauge, locking mechanism) and a cover module serving as a cosmetic cladding. This segmentation allows the cover module to be changed independently for different design variants without affecting the functional technology module, thus improving design flexibility while maintaining production efficiency through standardized functional components.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the entire lid handle unit is redesigned for different design variants, then design variety is improved, but production costs increase

Engineering Contradiction:
Improvedesign varietyVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the handle into a standardized technology module and a customizable cover module, the patent enables production of multiple design variants using the same expensive functional components. Only the cheaper cover module needs to be varied for different designs, significantly reducing production costs while maintaining design variety.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The technology module is designed as a universal platform that can be used across multiple design variants. The same pressure regulator, safety valve, and control mechanisms serve multiple cosmetic designs, reducing per-unit production costs through economies of scale while still offering consumers variety through different cover modules.

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

3Strength

If the lid handle is made as a fixed integrated unit, then structural integrity is improved, but cleaning and servicing accessibility worsens

Engineering Contradiction:
Improvestructural integrityVSAvoidcleaning accessibility
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The detachable connection between the cover module and technology module allows the cover to be removed for thorough cleaning of the functional elements. The technology module can be completely detached from the pot lid for servicing, while the cover module provides structural support when attached, balancing accessibility with structural integrity.

Inventive Principle:
Principle #1Segmentation
