Solution Overview

Problem

Existing push-button structures with display modules face issues such as short serviceable life due to cable arrangements, difficulty in assembly, fixed distances between circuit boards leading to distorted image display, and unstable signal transmission due to single-point contact, resulting in imprecise pressing and unclear images.

Innovation Solution

A key structure with a press cover, base plate, and flexible terminals that allow for flexible movement and electrical connection between the circuit structure and circuit board, enabling stable pressing force and adjustable distance for clear image display, using flexible terminals like pogo pins or springs to maintain image clarity and increase display range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cable arrangement configuration is used to connect display module to circuit board, then signal transmission is enabled, but serviceable life becomes short and assembly becomes difficult

Engineering Contradiction:
Improveserviceable lifeVSAvoidassembly difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts the cable arrangement from the connection system and replaces it with a pin-based connection structure. The display module is directly mounted on the circuit board with electrical pins providing the connection, eliminating the cable that caused assembly difficulties and reduced serviceable life.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a pressing member as an intermediary element between the display module and circuit board. This pressing member not only provides mechanical connection but also enables signal transmission and allows for adjustable distance, thereby improving reliability while simplifying assembly.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If fixed-type pins are used to connect upper and lower circuit boards, then connection stability is improved, but distance between circuit boards becomes fixed causing image distortion

Engineering Contradiction:
Improveconnection stabilityVSAvoidimage display quality
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The patent replaces fixed-type pins with a dynamic pressing member that can adjust its position. The pressing member includes a pressing portion that can move toward and away from the circuit board, allowing the distance to be adjusted to achieve optimal image display quality while maintaining connection stability through the pressing force.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If single-point method is used for connection between display module and control switch, then connection simplicity is achieved, but pressing stability becomes poor causing imprecise pressing

Engineering Contradiction:
Improveconnection simplicityVSAvoidpressing stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the pressing function into multiple contact points through the pressing member. Instead of a single-point connection, the pressing member provides distributed contact across the display module and circuit board, improving pressing stability while maintaining relative structural simplicity.

Inventive Principle:
Principle #1Segmentation
