Solution Overview

Problem

Existing controllers worn on one hand are unstable, making it difficult for users to perform operations effectively.

Innovation Solution

A wearing member with a support member, belt, sliding member, and locking mechanism that securely fastens around the hand, providing a stable grip and operation interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a controller is worn on one hand, then it allows for one-handed operation, but it becomes difficult to perform operations if the controller is not worn stably

Engineering Contradiction:
Improveone-handed operation capabilityVSAvoidwearing stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The belt is designed to be movable relative to the support member through a sliding member, allowing the belt length to be dynamically adjusted. This enables the wearing member to adapt to different hand sizes and shapes, ensuring stable wearing while maintaining one-handed operation capability. The dynamic adjustment mechanism resolves the contradiction by allowing the structure to change during use rather than being fixed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The wearing member is divided into distinct functional components: a support member for holding the controller, a belt for fastening, and a sliding member for adjustment. This segmentation allows each component to be optimized independently - the support member provides structural stability, the belt provides adjustable fastening, and together they achieve both stable wearing and one-handed operation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a belt and locking mechanism are added to improve wearing stability, then the controller can be worn stably on one hand, but the device complexity increases

Engineering Contradiction:
Improvewearing stabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sliding member enables the belt length to be adjusted by the user themselves without requiring additional tools or complex mechanisms. The user can simply slide the belt through the sliding member to achieve the desired length and secure it with the locking section. This self-service adjustment mechanism provides stable wearing while keeping the device complexity low.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The adjustment and locking functions are extracted as separate, simple components (sliding member and locking section) rather than being integrated into a complex single mechanism. This allows the belt system to provide stable wearing through modular, easy-to-understand components that can be manufactured and assembled simply.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A wearing member (2) includes a support member (31) extending in a first direction, a belt (34) extending from a site in the first direction of the support member (31), a sliding member (33) which is connected to one end of the belt (34) and which slides in the first direction along the support member (31), and a locking section which is provided in a direction opposite to the first direction in relation to the support member (31) and which locks a site on the other end side of the belt (34). In a state in which the belt (34) is locked by the locking section, a space (SP) surrounded by the support member (31) and the belt (34) is formed, and a part of the sliding member (33) is disposed inside the space (SP).
