Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is used to connect the housing and support, then the connection strength is improved, but adhesive overflow occurs affecting appearance and cleanliness
Solution Approach 1:
The patent extracts the adhesive from the general bonding area and confines it to a specific adhesive receiving portion. The through hole in the support structure channels the adhesive into this dedicated space, preventing it from overflowing onto the appearance surface while maintaining the bonding function.
Solution Approach 2:
The adhesive receiving portion acts as an intermediary structure between the bonding function and the appearance requirement. It receives and contains the adhesive, serving as a mediator that allows strong adhesion without compromising the clean appearance of the housing.
2Stability of the object's composition
If adhesive is used to connect housing and support, then the connection is stable, but maintenance and cleaning become difficult
Solution Approach 1:
By extracting the adhesive into a separate, accessible receiving portion through the through hole, the patent makes the adhesive accessible for maintenance purposes while maintaining its bonding function. This separation allows for easier inspection and potential replacement compared to embedded adhesive.
3Ease of manufacture
If traditional adhesive connection is used, then assembly is simple, but adhesive overflow affects waterproof performance
Solution Approach 1:
The adhesive receiving portion serves as an intermediary that contains the adhesive in a controlled manner. This prevents adhesive from creating pathways for water penetration while maintaining the simple assembly process of applying adhesive through the through hole.
Solution Approach 2:
The patent applies local quality by creating a specific adhesive receiving portion with particular geometric features at the adhesive application location. This localized structure ensures proper adhesive containment exactly where needed without affecting other areas of the housing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents adhesive overflow, maintaining the transducer assembly's appearance and functionality while enhancing waterproof performance and ease of assembly.
Implementation Method 1
A magnetic field generated by the coil when energized is coupled with a magnetic field of the magnetic member to drive the magnetic member to move
Implementation Method 2
The elastic sheet is connected to each of the support and the magnetic member. The magnetic member is capable of driving the elastic sheet to vibrate with a change of an energization direction of the coil
Implementation Method 3
An adhesive receiving portion is provided in the mounting cavity. The through hole corresponds to the adhesive receiving portion
