Solution Overview

Problem

Conventional game joystick switches face issues with low operation accuracy due to insufficient resilience in reset springs, large product size due to bulged electronic components, and complex structures with many accessories and inconvenient installation.

Innovation Solution

A novel game joystick switch design featuring a base with positioning holes and columns for accurate assembly, a metal fixing bracket for riveting, and integrated electronic components within the base, allowing for miniaturization, simplified structure, and easy installation by eliminating buckles and buckle points, with the reset spring positioned for optimal resilience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If electronic members are fixed on the housing outside the frame bracket, then the housing provides mounting surface, but the electronic members bulge out resulting in large product size

Engineering Contradiction:
Improveproduct sizeVSAvoidmounting convenience
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The electronic members are nested inside the frame bracket's containing space rather than being mounted on the external housing surface. The housing defines a containing space that accommodates the electronic members, achieving miniaturization by placing components internally rather than externally.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If the base is fixed on the housing by snap-fit of buckle point and buckle hole, then the connection is easy to assemble, but the combination is not tightened resulting in loose assembly

Engineering Contradiction:
Improveconnection strengthVSAvoidstructure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The buckle points are integrated into the housing structure itself rather than being separate components. The housing includes four buckle points at its corners that directly engage with corresponding buckle holes in the base, merging the connection feature into the main structure and eliminating the need for separate fastening accessories.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If the reset spring touches the rocker lever, then the reset spring can push the rocker lever, but the resilience is insufficient resulting in low operation accuracy

Engineering Contradiction:
Improveoperation accuracyVSAvoidreset spring resilience
Core Design Contradiction:
Manufacturing precisionVSForce

Solution Approach 1:

A first coupled member is introduced as an intermediary between the reset spring and the rocker lever. The reset spring pushes the first coupled member, which then transmits force to the rocker lever through a contact portion. This intermediary mechanism amplifies and optimizes the force transmission, improving operation accuracy while allowing the reset spring to maintain its resilient function.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Strength

If a metal fixing bracket is used to accommodate the housing and base, then the assembly is tightened and firm, but additional accessories are added increasing complexity

Engineering Contradiction:
Improveassembly tightnessVSAvoidnumber of accessories
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The metal fixing bracket is integrated with the housing structure, forming a unified component rather than a separate accessory. The housing includes the metal fixing bracket as part of its structure, with pins provided at corners for riveting to the base. This merging eliminates the need for separate fixing accessories while maintaining strong, tight assembly.

Inventive Principle:
Principle #5Merging (Combining)
