Solution Overview

Problem

Existing casters for equipment and furniture lack the ability to be produced in large volumes cost-effectively while accommodating individual customer configurations, leading to increased production costs and decreased efficiency.

Innovation Solution

A caster design featuring a support element with a replaceable, one-piece synthetic material cover that provides a continuous design surface, allowing for customization and high-volume, cost-effective production, with interlocking devices for secure attachment without visible fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If casters are produced in high volume with standardized designs, then production cost decreases and efficiency increases, but the ability to accommodate individual customer configurations is lost

Engineering Contradiction:
Improveproduction efficiencyVSAvoidcustomization capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The caster is divided into modular components: a standardized support element (housing, wheel, bearing) and interchangeable cover elements. The support element can be produced in high volume with standardized specifications, while different cover elements provide customization. This segmentation allows the base product to be manufactured efficiently while maintaining adaptability through component variation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized support element serves multiple functions across different caster variants, providing universal functionality for movement and support. Different cover elements can be attached to the same support element to create customized casters for different applications, making the core mechanism universal while the appearance and specific features are adaptable.

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

2Adaptability or versatility

If individualized caster configurations are produced to meet customer specifications, then customization capability improves, but production cost increases and efficiency decreases

Engineering Contradiction:
Improvecustomization capabilityVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

By segmenting the caster into standardized support elements and interchangeable covers, the patent enables customization without requiring complete individual production of each caster. The support element is produced once in high volume, and different covers are added later to meet specific customer requirements, maintaining production efficiency while achieving customization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support element is pre-produced in high volume with standardized specifications before the customization stage. This preliminary mass production of the core component establishes a foundation for efficient customization, as the expensive and time-consuming parts are already manufactured, and only the covers need to be adapted or attached later.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple caster variants are produced to meet diverse customer requirements, then adaptability improves, but the number of production figures decreases and cost increases

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

Solution Approach 1:

A single standardized support element design serves as the basis for multiple caster variants. The same support element housing, wheel assembly, and bearing mechanism can accommodate different cover styles, materials, and configurations, allowing the manufacturer to offer diverse product variants without maintaining separate production lines for each variant, thus controlling production costs while maintaining product variety.

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

Solution Approach 2:

The caster system is segmented into a common platform (support element) and variable components (covers). This segmentation allows the core expensive components to be produced once and reused across multiple variants, while only the relatively inexpensive covers need to be varied to create different product versions, significantly reducing the overall cost of producing multiple variants.

Inventive Principle:
Principle #1Segmentation
