Solution Overview

Problem

Existing electronic shelf labels (ESLs) installed on cantilever-type peg hooks interfere with the hanging and removal of products, making it difficult to manage prices and information on display stands effectively.

Innovation Solution

A label apparatus for peg hooks featuring a detachable holder with engaging portions and clamping mechanisms that allow secure attachment without obstructing product placement, combined with a body design that minimizes interference with the peg hook structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If an electronic shelf label (ESL) is installed on a peg hook, then price and information management is improved, but product hanging and removal operations become difficult due to interference

Engineering Contradiction:
Improveprice and information managementVSAvoidproduct hanging and removal
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The label apparatus is divided into a detachable holder portion and a body portion. The holder can be attached to or separated from the peg hook independently, allowing the label to be mounted on the hook without permanently obstructing product handling operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holder is designed with dynamic attachment capability, allowing it to be fixed to the peg hook when information display is needed and removed when product handling is required. This dynamic configuration resolves the conflict between information management and operational ease.

Inventive Principle:
Principle #15Dynamics

2Loss of information

If a label apparatus is attached to a peg hook, then information display is achieved, but the structure interferes with product placement on the hook

Engineering Contradiction:
Improveproduct identification and displayVSAvoidproduct placement flexibility
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

By separating the label apparatus into a detachable holder and a fixed body, the system maintains adaptability. The holder can be positioned to minimize interference with product placement, while the body remains securely attached for continuous information display.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable holder acts as an intermediary between the label apparatus and the peg hook. It provides a mounting mechanism that allows the label to be displayed without permanently altering the peg hook's functionality for product placement.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a secure attachment mechanism is used to fix the label apparatus to the peg hook, then reliability of attachment is improved, but the mechanism may obstruct product hanging operations

Engineering Contradiction:
Improveattachment securityVSAvoidproduct hanging and removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The attachment system is segmented into a detachable holder with engaging portions and the peg hook structure. This segmentation allows the holder to be securely attached when needed while enabling easy detachment to restore full product handling capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable holder can be discarded (removed) from the peg hook when product handling operations require unobstructed access, and recovered (reattached) when information display is needed, balancing attachment reliability with operational ease.

Inventive Principle:
Principle #34Discarding and recovering
