Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the glue slot opening is not a closed structure, then the structure is simple and easy to manufacture, but the glue flows uncontrollably and spills during dispensing and curing

Engineering Contradiction:
Improveglue dispensing controlVSAvoidglue slot structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The base is divided into multiple sections with the glue slot formed by grooves on the sidewalls, creating distinct dispensing and curing zones. This segmentation allows controlled glue flow paths while maintaining structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses the base sidewalls and mounting brackets to form flexible sealing surfaces that create closed dispensing ports and curing slots. These thin structural elements provide the necessary sealing function without adding complex components.

Inventive Principle:
Principle #30Flexible shells and thin films

2Manufacturing precision

If the glue slot opening is open structure, then the manufacturing process is simple, but the glue spills at the slot opening affecting dispensing effect

Engineering Contradiction:
Improveglue dispensing effectVSAvoidglue slot structure
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The mounting bracket is pre-positioned on the base to form the closed dispensing port structure before glue dispensing. This preliminary arrangement ensures precise glue placement and prevents spillage during the subsequent dispensing and curing operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mounting bracket serves as an intermediary component that creates the closed dispensing port and curing slot structures. It mediates between the simple base structure and the requirement for controlled glue flow, providing sealing surfaces without requiring complex modifications to the base itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of substance

If the glue slot opening is not closed, then the structure is simple, but the glue is wasted during the oven curing process

Engineering Contradiction:
Improveglue wasteVSAvoidglue slot structure
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The curing process area is segmented into a closed curing slot formed by the base groove and mounting bracket. This segmentation contains the glue within the slot during oven curing, preventing waste while maintaining structural simplicity through the use of existing components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting bracket creates flexible sealing surfaces that form the closed curing slot structure. These thin structural elements provide effective glue containment during curing without adding significant complexity to the overall device structure.

Inventive Principle:
Principle #30Flexible shells and thin films
