Evaluation of perceived quality of automotive wiring harnesses and improvement measures

Vehicle perceived quality (sensory evaluation) means that customers feel the quality and characteristics of automotive products through "seeing, hearing, touching and smelling", which are suitable for the needs and expectations of customers in specific market segments. Perceived quality is characterized by subjectivity, abstraction, relativity, and incompleteness. 1. Specific judgment content of wire harness perception quality 1. Visually: application of low-gloss/high-gloss external covering material; improvement of material wear resistance, scratch resistance and pollution resistance; uniform spacing between coated adhesive tapes, natural transition between skeleton and branches, no adhesive opening; no single wire loose or tight at connector position; 1. There is no obvious change in the harness from the trunk to the two nodes of the branch, and the wire diameter shall not be changed due to too many connecting wires; the engine compartment shall be laid horizontally and vertically as far as possible, and the plastic support shall be designed as far as possible; 2. Tactile: it has a certain degree of flexibility, which is convenient for the assembly of the harness; 3. Auditory: the harness is firm, and the static and dynamic interference is reasonable, so it is necessary to reserve the installation length of the harness for noise reduction; 4. Smell: Car odor: Consumer demand often appears in two aspects: ① The harmful substances in the car do not exceed the standard; ② There is no odor in the car. GB/T27630-2011 Guidelines for the Assessment of Air Quality in Passenger Cars stipulates the implementation standard requirements for the concentration of organic matter in the car: ① Benzene ≤ 0.11mg/m ³ ② Toluene ≤ 1.10 mg/m ³ ③ Xylene ≤ 1.50mg/m ³ ④ Ethylbenzene ≤ 1.50 mg/m ³ ⑤ Styrene ≤ 0.26 mg/m ³ ⑥ Formaldehyde ≤ 0.10 mg/m ³ ⑦ Acetaldehyde ≤ 0.05mg/m ³ ⑧ Acrolein ≤ 0.05mg/m ³ 2. Improve customer perception of quality factors 1. Reliability: Reliability means that service commitments can be fulfilled correctly and reliably. 1. Service commitment to customers shall be kept, and all promised things shall be done as much as possible, and those that cannot be done shall not be promised easily, which will affect the customer's feeling of service quality; 2. Sensitivity: Sensitivity is the willingness to help customers and provide them with fast service, and the customer's requirements, inquiries and complaints shall be responded and handled quickly, and handled from the customer's standpoint; 3. Credibility: Integrity means that the enterprise should have professional knowledge, courtesy and ability to enhance customers' trust in the company; 4. Tangibility: "Tangibility" refers to physical facilities, equipment, personnel, written documents, etc., to enhance customers' perception and feeling of service quality.
