Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional oyster shucking methods result in injuries, hygiene issues, and reduced productivity due to the need for manual handling, leading to blisters, contamination, and repetitive strain injuries, which increase costs and diminish product value.

Innovation Solution

An apparatus that stabilizes oysters using support and wedging members, allowing for one-handed shucking, with adjustable components to accommodate various oyster sizes and shapes, and integrates a water dispensing system to maintain hygiene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual two-handed shucking method is used, then the worker can control the knife and oyster, but the worker suffers from injuries, blisters, and repetitive strain injuries

Engineering Contradiction:

Improvemanual controlVSAvoidinjuries and contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a shucking device with a clamp and support surface as an intermediary tool. The clamp securely holds the oyster shell while the support surface stabilizes the oyster body, allowing the worker to operate the knife with one hand without direct manual contact with the oyster, thereby preventing injuries and contamination.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the manual two-handed mechanical system with a mechanical shucking device that uses a clamp mechanism and support surface. This mechanical substitution eliminates the need for direct hand contact with the oyster, reducing repetitive strain injuries and the risk of cuts while maintaining control over the shucking process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If conventional manual shucking process is used, then the worker can access the oyster organism, but the process results in contamination and hygiene issues

Engineering Contradiction:

Improveshucking speedVSAvoidcontamination and debris

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The shucking device acts as an intermediary barrier between the worker's hands and the oyster. The clamp and support surface contain the oyster securely, preventing direct contact and potential contamination from hand debris or blood, while still allowing efficient access to the oyster organism for shucking.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the harmful elements (direct hand contact, bench space contamination) from the shucking process by using a dedicated shucking device with a clamp and support surface. This separation eliminates the source of contamination while maintaining the productivity of the shucking operation.

Inventive Principle:

Principle #2Taking out (Extraction)

3Object-affected harmful factors

If one-handed shucking with stabilization apparatus is used, then the worker's safety and productivity improve, but the device complexity increases

Engineering Contradiction:

Improveinjury reductionVSAvoidshucking apparatus structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shucking device is segmented into distinct functional components: a clamp mechanism for securing the shell, a support surface for stabilizing the oyster body, and a mounting assembly. This segmentation allows each component to perform its specific function efficiently while keeping the overall device relatively simple and easy to understand.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of making the oyster move or requiring two-handed operation, the patent inverts the approach by making the device adapt to hold the oyster stationary. The clamp and support surface are designed to conform to the oyster's shape and size, simplifying the operation to one-handed knife control while reducing the perceived complexity through intuitive design.

Inventive Principle:

Principle #13The other way round (Inversion)

4Adaptability or versatility

If adjustable support members are added to accommodate different oyster sizes, then the device's versatility improves, but the device complexity increases

Engineering Contradiction:

Improveoyster size accommodationVSAvoidadjustable components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support members are designed with adjustable positions that can be dynamically configured to accommodate different oyster sizes and shapes. This dynamic adaptability allows the same device to handle a variety of oyster types without requiring multiple specialized tools, while the adjustment mechanism remains relatively simple to operate.

Inventive Principle:

Principle #15Dynamics

AI summary

An apparatus (270) for shucking oysters includes a shucking head (272) adapted to be mounted on a mounting assembly. The shucking head includes means for supporting the oyster in a position so that a lower shell of the oyster is supported on a pair of arms (282, 284) of support members (274, 276). The shucking head also includes means for wedging the oyster in a position so that an end of the oyster is wedged against a selected wedging member (278, 280). The arrangement of support members and wedging members is such that the oyster is held in a stable position to allow a person to use a knife to shuck the oyster with one hand.
