Solution Overview

Problem

Existing stands for electronic keyboard instruments lack versatility and stability, particularly in terms of attachment mechanisms that allow for secure and adjustable positioning.

Innovation Solution

A stand design featuring a lateral spanning member with connecting members and leg members, incorporating different engagement constructions for each leg attachment, ensuring secure and adjustable attachment of keyboard instruments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional stand with four leg members screwed to the keyboard instrument is used, then the stand can be attached to the instrument, but the attachment mechanism lacks versatility and adjustability

Engineering Contradiction:

Improveattachment versatilityVSAvoidengagement construction complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The stand divides the attachment mechanism into separate engagement constructions for different leg members. The first leg member uses a screwing engagement construction, while the second leg member uses a fitting engagement construction. This segmentation allows each leg to be attached using the most appropriate method for its specific requirements, enhancing overall versatility without requiring all legs to use a complex unified mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stand employs multiple types of engagement constructions (screwing and fitting) within the same attachment system, making the attachment mechanism universal enough to handle different attachment scenarios. The lateral spanning member with multiple engagement portions can accommodate various leg member types and attachment preferences, providing multi-functionality without excessive complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If the same engagement construction is used for all leg members, then the manufacturing process is simplified, but the attachment stability and adjustability are reduced

Engineering Contradiction:

Improveattachment stabilityVSAvoidengagement construction uniformity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

Different engagement constructions are applied to different leg members based on their specific attachment requirements. The first leg member uses a screwing construction for enhanced stability where needed, while the second leg member uses a fitting construction for simpler attachment. This local differentiation of engagement methods optimizes attachment stability at each specific location without requiring complex uniform manufacturing across all components.

AI summary

A stand includes a lateral spanning member, a connecting member configured to be fixed to the lateral spanning member and having a first engagement portion and a second engagement portion, and a front leg comprising a first engagement target portion configured to be brought into engagement with the first engagement portion and a back leg comprising a second engagement target portion configured to be brought into engagement with the second engagement portion, and a first engagement construction in which the first engagement target portion is brought into engagement with the first t engagement portion and a second engagement construction in which the second engagement target portion is brought into engagement with the second engagement portion are different from each other.
