Solution Overview

Problem

Existing coin cash registers are time-consuming to empty due to the need for manual handling and difficulty in simultaneously opening the door and removing coins, leading to incomplete emptying.

Innovation Solution

A coin cash register with a sliding door and an inclined support base that allows coins to slide out through a front-side removal opening, facilitated by a multi-angled bend design and a lock for secure access, making it easier to empty and service-friendly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pivoting door or flap is used to close the removal opening, then the coin cash register can be securely closed, but the door may pop open due to internal coin pressure and manual handling becomes difficult

Engineering Contradiction:
Improvesecure closingVSAvoidmanual handling
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Instead of using a conventional pivoting door that opens outward against coin pressure, the patent uses a sliding door that moves horizontally along guide rails. This inversion of the door mechanism eliminates the popping problem by providing a linear sliding motion guided by rails, allowing the door to be securely closed while enabling easy manual operation without being forced open by internal pressure.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If coins are emptied manually by hand, then complete emptying can be achieved, but the process is time-consuming and reduces service efficiency

Engineering Contradiction:
Improvecomplete emptyingVSAvoidservice efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements a coin discharge mechanism where coins automatically slide out of the coin cash register through a discharge opening when the sliding door is opened. The inclined support base and coin discharge opening work together to enable coins to exit automatically using gravity, eliminating the need for manual handling and significantly improving service efficiency while ensuring complete emptying.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the removal opening is positioned in the front of the housing, then easy access for servicing is achieved, but the sliding door requires complex guiding mechanisms to prevent bending

Engineering Contradiction:
Improveservice accessVSAvoidguiding mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces guide rails as an intermediary element between the sliding door and the housing. These guide rails provide a simple yet effective guiding mechanism that prevents the sliding door from bending or misaligning during horizontal movement. The guide rails maintain the door's positional stability while allowing smooth sliding operation, achieving easy service access without excessive complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
