Solution Overview

Problem

Prior art product display cases are prone to collapse upon accidental impact and have complex assembly processes, making them unstable and difficult to assemble.

Innovation Solution

A product display case design featuring a frame with vertical members and shelves supported by folded portions of the vertical members, where tongues on the supports slot into holes on the shelves to secure them, providing stability and simplifying assembly by eliminating the need for complex connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If shelves are supported by protuberances sliding in slots on the rear wall, then the display case can be assembled with simple components, but the shelves become unstable and collapse when struck accidentally

Engineering Contradiction:
Improveassembly simplicityVSAvoidshelf stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The support merges the functions of the vertical member, support structure, and shelf connector into a single integrated component. The folded portion of the vertical member creates an L-shaped support that is made as one with the vertical member, eliminating separate connection components and creating a more stable structure that resists accidental impacts while maintaining ease of assembly through folding.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If multiple separate components are used to connect shelves to the frame, then the display case allows for easy disassembly, but the assembly process becomes complex and time-consuming

Engineering Contradiction:
Improvedisassembly easeVSAvoidassembly complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support integrates multiple functions into a single component made as one with the vertical member, reducing the number of separate parts that need to be assembled. The folded portion creates an integrated L-shaped support that combines the vertical member extension, support surface, and shelf connector functions, simplifying the assembly process while maintaining ease of disassembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support is pre-formed by folding the vertical member into the L-shape configuration before final assembly with the shelf. This preliminary folding action prepares the support in its final configuration, eliminating the need for complex on-site assembly operations and reducing the number of steps required during the assembly process.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the rear wall is made of flexible material to allow folding, then the display case can be collapsed for storage, but the wall deforms elastically under impact causing shelves to become unstable

Engineering Contradiction:
Improvecollapsibility for storageVSAvoidshelf stability under impact
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The support merges the structural support function with the flexible material properties, creating a structure that can deform elastically under impact but maintains shelf stability. The L-shaped support made as one with the vertical member distributes impact forces more effectively than separate connection components, allowing the flexible material to provide both collapsibility and impact resistance.

Inventive Principle:
Principle #5Merging (Combining)
