Solution Overview

Problem

Existing compressor upper cover assemblies face challenges in achieving a good sealing effect due to the inconvenience of sealing wiring terminals and terminal posts, often resulting in gaps, especially since the terminal post fixing base is partially surrounded by the terminal post protection cover and the positions of wiring terminals are not constant.

Innovation Solution

A sealing cover with wire guide slots and guide holes allows for easy insertion of wiring terminals and injection of sealant, ensuring the terminal posts can penetrate and make contact, providing a secure electrical connection and effective sealing when assembled over the terminal post fixing base.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the terminal post protection cover is used to cover the terminal posts and wiring terminals, then the terminal posts and wiring terminals are protected, but it becomes extremely inconvenient to seal the wiring terminals, terminal posts, and terminal post protection cover, resulting in gaps and poor sealing effect

Engineering Contradiction:
Improvesealing effectVSAvoidconvenience of sealing operation
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The invention divides the sealing structure into multiple parts: a sealing cover that covers the terminal post protection cover, wire guide slots for guiding wiring terminals, and guide holes for guiding terminal posts. This segmentation allows each component to perform its specific function independently, making the sealing operation convenient and effective.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing cover acts as an intermediary component between the terminal post protection cover and the external environment. It provides a dedicated sealing structure with wire guide slots and guide holes that facilitate the sealing process without requiring direct access to the wiring terminals and terminal posts, thus solving the convenience issue.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the wiring terminals are positioned at variable locations, then flexibility in connection is improved, but gaps are formed between the wiring terminals and the terminal post protection cover, preventing good sealing

Engineering Contradiction:
Improveposition flexibility of wiring terminalsVSAvoidgaps in sealing
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The sealing cover provides different local structures for different functions: wire guide slots for wiring terminals, guide holes for terminal posts, and sealing surfaces for the terminal post protection cover. Each local area is optimized for its specific purpose, allowing variable positioning of wiring terminals while maintaining sealing integrity through the dedicated wire guide slots.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If the terminal post fixing base is half surrounded by the terminal post protection cover, then the terminal posts are protected, but the sealing operation becomes extremely inconvenient and gaps are formed

Engineering Contradiction:
Improveprotection of terminal postsVSAvoidease of sealing assembly
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The sealing cover is designed with pre-formed wire guide slots and guide holes that prepare the sealing path in advance. This preliminary action allows the wiring terminals and terminal posts to be guided into their correct positions during assembly, making the sealing operation convenient and ensuring complete sealing without gaps.

Inventive Principle:
Principle #10Preliminary action
